Countdown

Among the things you get to observe at signalized intersections are the behavior of drivers given the setting of the traffic lights. While the cyclic transition from red to green to amber and then to red again seems routine and possibly trivial to many, it is an opportunity for traffic engineers to examine how drivers react to the lights. Among the most notable behavior are common violations like beating the red light and occupying the area within the yellow box despite full awareness that the exit is already full.

Then there are the not so obvious but risky habit of some drivers to beat the green light. That’s when a driver anticipates the green light and proceeds to move prior to the signal and before the intersection is clear of any vehicles or pedestrians that may have been caught in the change in signals. It is a practice that increases the probability of a road crash occurring as the clearance interval for vehicles whose paths may be in conflict is drastically reduced. This is a habit of many drivers who are familiar with the sequence of signals at an intersection and who know when its their turn for the green light.

In most cases, drivers and pedestrians are unaware of the length of time available for them to cross the street or intersection. There are no indications for when the lights will change and only familiarity would allow for drivers or pedestrians to estimate when it would be their turn to proceed. In Japan, many intersections play music during that tends to speed up when the signal will be changing. This audible indicator allows for both the blind and the busy to know whether it is safe to cross the street and if there is enough time to do so. It is also something that is probably taught to children for them to more easily know when it is safe for them to cross the street.

There is another innovation to traffic signals that is surely welcome to pedestrians and motorists alike but which may also have its disadvantages. I am referring to the countdown timer, which provides road users the information about the lengths of green and red signals (Note: Amber or yellow is usually fixed at 3 seconds.).  From the perspective of energy efficiency, such information may allow motorists to turn off their engines, usually done when one practices eco-driving, resulting in fuel savings. Meanwhile, drivers of vehicles approaching an intersection may be able to tell if there is enough time for them to do so, and if there isn’t enough time they may be able to slow down their vehicles to stop at the next red light. Countdown timers may also be a helpful tool for enforcement as the timers establish that a driver should be aware of the time. Thus, a driver can no longer reason with the apprehending officer that he/she was not aware of the remaining time for movement.

Pedestrians may also benefit from the knowledge of available time to make a safe crossing. This information should ultimately reduce the need for running in order to completely cross the street. The photo below shows the new countdown timer installed for the southbound through movement at the Katipunan Avenue (C5) – C.P. Garcia Avenue intersection.

One possible disadvantage would be that aggressive drivers may still try to beat the red light by speeding up upon knowing what amount of time is available for them. Another disadvantage relates to beating the green light as even those unfamiliar with the signal sequence will have the information of how much time remains before they can proceed. Thus, many driver and riders start revving up their engines and push on their gears to anticipate the green signal. You can even imagine the countdown timer being used as if it were ticking towards to start of a race.

Despite the disadvantages mentioned, countdown timers should prove to be more beneficial than detrimental in most situations. In fact, countdown timers like the ones already installed at intersections in Bonifacio Global City should enhance traffic safety provided that these devices are fully complemented by enforcers who would flag down motorists and pedestrians who would attempt risky actions in relation to the timing device. Of course, from the research perspective there needs to be a scientific assessment of the actual impacts of countdown timers much like the studies already conducted elsewhere to determine and even measure the effects of these devices on both motorists and pedestrians. Only then can we truly say if they do enhance safety and promote more efficient operations at a signalized intersection.

Enforceable?

Whenever laws and regulations are crafted, one basic question that needs to be considered pertains to whether there is capacity to enforce such laws or regulations. This is quite logical and appeals to common sense since laws and regulations are practically prints on paper that will not have any impacts if not enforced properly and fairly. I mention “fairly” here because laws and regulation may also be the subject of abusive enforcement. That is, there have been cases where motorists are flagged down and charged with violations that are taken out of the context given the traffic conditions, and where the number of apprehensions are related to quotas set by authorities.

Take the case of the unwarranted or illegal use of sirens (wangwang) in the past. There were laws and regulations for its use  but for a long time these laws and regulations were not enforced properly, leading to the wangwang’s abuse by many unscrupulous people. Almost everyone have practically given up on this abuse of the siren when a newly elected President expressed his dismay and ordered the eradication of illegal sirens. Almost overnight, “wangwangs” were confiscated by authorities inspired by the Commander-in-Chief’s orders or removed by owners themselves for fear of the law bearing down on them. This was enforcement at its best. Unfortunately, it was not replicated for other traffic laws and regulations, wasting valuable momentum and the opportunity to make things right along our streets and highways.

Quezon City’s Green Building Ordinance is quite good and well-meaning. It is very timely and relevant, and even includes provisions for upgrading transport in that city. Among others, it requires that tricycles be transformed into cleaner vehicles by stipulating the replacement of 2-stroke and even 4-stroke motorcycles with LPG or electric models. To date, nothing significant has been achieved to address issues pertaining to the tens of thousands of tricycles in Quezon City. The construction of green buildings in Quezon City cannot be mainly attributed to the ordinance but rather to owners and designers who are now much more aware of climate change and its impacts, and are progressive enough to design buildings that are environment-friendly. Of course, there are those who take to the “green” bandwagon but do nothing towards this end. Are these subject to evaluations and inspections that are the equivalent of enforcement?

Now comes a bicycle ordinance from Pasig City that is formally the “Bicycle Transportation Promotion Ordinance of 2011.” It is also good and well-meaning but the jury will definitely be out there if this initiative will be a successful and sustainable one. I am quite hopeful that it would be and not just end up as an example of coming up with laws because anything about the environment is in these days. The provision in the ordinance designating bicycle lanes and requiring establishments to provide bicycle racks for parking are all good but we have seen this before in an even bigger scale in the City of Marikina. There they constructed bikeways practically connecting all parts of the city and they were quite aggressive even after foreign support had ended. Politics and shortcomings (I wouldn’t say failure.) in encouraging people to cycle have made much of the on-street bicycle lanes practically taken over by motorized transport. Bicycle racks there are also being used by motorcycles and scooters. Pasig should learn from these experiences and it is hoped that the city succeed and become another example of EST to be replicated in other Philippine cities.

School traffic generation – Part 1

One thing I will miss about summers is the relatively light traffic along Katipunan Avenue, which is where I pass through almost everyday between my home and workplace. There is still some congestion during the mid-day and the afternoons but these are typically due to truck traffic as Circumferential Road 5 (C5) is a truck route. During the rest of the year, however, with the exception of most weekends and holidays, severe congestion is experienced along Katipunan during the peak periods, particularly in the mornings between 6:30 AM and 7:30 AM. This is due primarily to the traffic generated by schools along Katipunan Avenue, most notably the Ateneo De Manila University and Miriam College. The following photos show typical traffic conditions along C5 during the peak periods.

Congestion along the Katipunan southbound service road leading to the U-turn slot underneath the Aurora Blvd. overpass

Traffic along the southbound service road leads to a U-turn slot under the overpass where many vehicles turn, heading in the general direction of Ateneo. Most turn here in order to enter the university via its Gate 1, which is the main access to the Grade School. On most times, congestion is caused by these vehicles turning right at Gate 1 as they effectively occupy the two lanes of the northbound service road and block all other traffic. This is shown in the following photo where it is clear that vehicles bound for Ateneo and turning at Gate 1 are the main cause of congestion. Beyond Gate 1, the traffic lanes are practically free of congestion.

Vehicles turning right to Ateneo’s Gate 1 blocking traffic along the Katipunan northbound service road

The afternoon peak is exacerbated by traffic generated by these schools that lead to longer periods of congestion as the number of private vehicle traffic dramatically increases when there are classes between June and April. Meanwhile, there is a noticeable decrease in traffic during the weekends and holidays. Such phenomenon is mostly attributable to the trip generation characteristics of schools, and especially those that tend towards the generation of much private vehicles. Ateneo and Miriam along Katipunan are just two examples. The traffic they generate and the consequential congestion is replicated in other places as well, giving headaches to motorists and commuters passing along major roads affected by these schools. Ortigas Avenue, for example, is usually congested during the weekdays because of traffic generated by LaSalle Greenhills, and ADB Avenue at the Ortigas Center is usually congested due to traffic attributed to Poveda.

Traffic Congestion in Metro Manila: Is the UVVRP Still Effective? -Conclusion

The MMDA always reports what it claims as improvements of travel speeds along EDSA that past years. They have pointed to this as evidence that traffic congestion is being addressed and that programs like the UVVRP are effective in curbing congestion. However, many traffic experts have cautioned against making sweeping generalizations pertaining to the effectiveness of schemes especially if the evidence put forward is limited and where data seems to have been collected under undesirable (read: unscientific) circumstances.

The MMDA also has been using and to some extent overextending its use of a micro-simulation software that is employs to demonstrate the potential effectiveness of its proposed traffic schemes. The software has an excellent animation feature that can make the untrained eye believe in what is being shown as The problem here is when one realizes that computer software will only show what the programmer/operator wants, and is perhaps an example where the term “garbage in, garbage out” is very much applicable. And this is especially true should the computer model be uncalibrated and unvalidated according to guidelines that are well established, and extensively discussed and deliberated in a wealth of academic references. The fallacy of employing advanced tools to demonstrate how one’s proposal is better than another was highlighted when the DPWH acquired the same tool and came up with an entirely different result for an analysis being made for the same project by that agency and the MMDA. Surely this resulted in confusion as the outcomes of the simulation efforts of both agencies practically negated each other.

It should be pointed out that such micro-simulation software is unsuitable for the task of determining whether metro-wide schemes such as the UVVRP is still effective given the actions of those affected by the scheme. What is required is a macroscopic model that would take into account the travel characteristics of populations in Metro Manila and its surrounding areas (cities and towns in the provinces of Rizal, Bulacan, Cavite, Laguna). There are quite a few of these models available but most if not all were derived from the one developed under the Metro Manila Urban Transport Integration Study (MMUTIS) that was completed in 1999. The main beneficiary from the outcomes of MMUTIS happens to be the MMDA but for some reason, that agency failed to build capacity for maintaining and updating/upgrading the model. As such, the agency missed a great opportunity to invest in something that they could have used to develop and evaluate traffic schemes to address congestion and other traffic issues in Metro Manila, as well as to assess the impacts of new developments.

Metro Manila has come to a point where its options for alleviating congestion are becoming more and more limited. The combination of a still increasing rate of motorization and private vehicle use have definitely contributed to congestion while there are also perceptions of a decline in public transport use in the metropolis. The share of public transport users in most Philippine cities and municipalities range from 80 – 90 %, while in many highly urbanized cities the tendency seems to be a decline for this share as more people are choosing to purchase motorcycles to enhance their mobility and as a substitute to cars. This trend towards motorcycle use cannot be denied based on the steep increase in ownership and the sheer number of motorcycles we observe in traffic everyday.

Metro Manila needs to retain the substantial public transport share while accepting that motorcycle ownership will continue to chip off commuters. The latter phenomenon can be slowed down should authorities strictly enforce traffic rules and regulations on motorcyclists, effectively erasing the notion that the latter group is “exempted” from such. The bigger and more urgent issue is how to put up long overdue mass transport infrastructure that is direly needed in order to create another opportunity for rationalization transport services. We seem to like that word “rationalization” without really understanding and acting on what is required to once and for all address transport problems in the metropolis. We are not lacking for examples of good practices that are both effective and sustainable including those in the capital cities of our ASEAN neighbors. However, we seem to be unable to deliver on the infrastructure part that we have tended to over-rely on a TDM scheme that has long lost much of its effectiveness. The evidence is quite strong for this conclusion and perhaps we should stop being in denial in as far as the UVVRP’s effectiveness is concerned. Efforts should be turned towards building the necessary infrastructure and making public transport attractive so that private car and motorcycle users will be left with no excuse to shift to public transport use. It is inevitable that at some time they will understand the cost of congestion and that they will have to pay for their part in congestion like what is being done along tollways or, in the more sophisticated and mature example, Singapore. But this cannot be realized if we continue to fail in putting up the infrastructure Metro Manila so direly requires.

Traffic congestion in Metro Manila: Is the UVVRP still effective? – Part 2

In the past decade, there has been a sharp rise in the motorcycle ownership around the country and especially in Metro Manila. From about 1 million motorcycles registered in 2000, the number has increased to 3.2 million in 2009, a 320% increase over a period of 10 years. Motorcycles have become associated with mobility, in this case the motorized kind, and have become the mode of choice for many who choose to have their own vehicles but cannot afford a four-wheeler. These people also choose not to take public transport for a variety of reasons but mainly as they perceive their mobility to be limited should they use public transport services that are available to them. This rise of the motorcycle is also a response to the restrictions brought about by UVVRP with the scheme not covering motorcycles. In fact, should motorcycles be included in the UVVRP, it would be a nightmare for traffic enforcers to apprehend riders considering how they maneuver in traffic. Add to this the perception and attitude of riders that motorcycles are practically exempt from traffic rules and regulations (and traffic schemes!). One only needs to observe their behavior to validate the argument.

To understand UVVRP, it must also be assessed in the context of its original implementation when Metro Manila had to contend with congestion due to infrastructure projects being constructed everywhere during the 1990’s. EDSA MRT was being constructed, interchanges were also being put up, and a number of bridges were being widened to accommodate the increasing travel demand. Road widening projects generally benefit private vehicle users more than public transport users. In the case of Metro Manila, many areas are already built-up and acquisition of right of way for widening is quite difficult for existing roads. As such, it is very difficult to increase road capacities to accommodate the steady increase in the number of vehicles.

In transportation engineering, when traffic/transport systems management (TEM) techniques are no longer effective or yield marginal improvements we turn to travel demand management (TDM) schemes to alleviate congestion. In the former, we try to address congestion by tweaking the system (i.e., infrastructure) through road widening, adjustment of traffic signal settings, etc. while in the latter, we go to the root of the problem and try to manage the trips emanating from the trip generation characteristics of various land uses interacting with each other. By addressing the trip generation characteristics through restrictions, we influence travel demand and hopefully lessen traffic during the peak periods while distributing these to others.

This is the essence of UVVRP where the coding scheme targets particular groups of private cars (according to the end number on the license plate) each weekday. Meanwhile, the scheme is not implemented during weekends due to the perception that, perhaps, travel demand is less or more spread out during Saturdays and Sundays. However, there is a problem with this approach as the traffic taken away from the peak hours are transferred to other times of the day, thereby causing in some cases the extension of what was originally a peak hour unto a longer period. What was before a morning peak of say 7:30 – 8:30 AM becomes spread out into a peak period of 7:00 – 9:00 AM. The problem here is when you have major traffic generators like central business districts (e.g., Makati and Ortigas) where congestion is experience for more than 2 hours (e.g., 7:00 – 10:00 AM or 4:00 – 7:00 PM).

The UVVRP is not implemented in all of Metro Manila. Several LGUs, particularly those in the outer areas like Marikina City and Pateros. This is simply due to the information and observations of these cities that their roads are not affected by the build-up of traffic since most traffic is bound for the CBDs located in Makati, Pasig, Mandaluyong, Quezon City and Manila. This is the case also for LGUs in the periphery of Metro Manila like the towns in the province of Rizal, which is to the east of the metropolis, where the typical behavior of traffic is outbound in the morning and inbound in the afternoon. The great disparity between inbound and outbound traffic is evident in the traffic along Ortigas Avenue where authorities have even implemented a counterflow scheme to increase westbound road capacity.

There have also been observations of traffic easing up during the mid-day. As such, the MMDA introduced a window from 10:00 AM to 3:00 PM to allow all vehicles to travel during that period while retaining the restrictions of the number coding scheme from 7:00 – 10:00 AM and 3:00 – 7:00 PM. However, while many LGUs applied the window, some and particularly those found in central part of the Metropolis like Makati, retained the 7:00 AM – 7:00 PM ban. This stems from their perspective that traffic does not ease up at all (e.g., try driving along Gil Puyat Ave. during lunchtime) along their streets during the window period.

Nowadays, there seems to be the general perception that one can no longer distinguish between traffic during the coding period and the window. Traffic congestion is everywhere and there are few opportunities for road widening. Traffic signal control adjustments are limited to those intersections where signals have been retained (mostly in Makati) since the MMDA replaced signalized intersections with U-turn slots during a past administration where the U-turn was hailed as the solution to the traffic mess.

Traffic congestion in Metro Manila: Is the UVVRP still effective? – Part 1

I was interviewed last week about the traffic congestion generally experienced along major roads in Metro Manila. I was asked whether I thought the Unified Vehicular Volume Reduction Program (UVVRP) more popularly known as the number coding scheme was still effective, and I replied that based on what we are experiencing it is obviously not effective anymore. The reasoning here can be traced from the fact that when the scheme was first formulated and implemented, the main assumption was that if the number of license plates on registered vehicles were equally distributed among the 10 digits (1 to 0), then by restricting 2 digits indicated as the end/last number on a plate we could automatically have a 20% reduction in the number vehicles. This rather simplistic assumption was sound at the time but apparently did not take into consideration that eventually, people owning vehicles will be able to adjust to the scheme one way or another.

One way to adjust when the number coding scheme was implemented was to change traveling times. Everyone knew that the scheme was enforced from 7:00 AM to 7:00 PM (i.e., there was no 10:00 AM to 3:00 PM window at the time) and so people only had to travel from the origins to their destinations before 7:00 AM. Similarly, they would travel back after 7:00 PM, which partly explains why after 7:00 PM there is usually traffic congestion due to “coding” vehicles coming out to travel. In effect, the “coding” vehicle is not absent from the streets that day.  Instead, it is only used during the time outside of the “coding” or restricted period.

Another way that was actually a desired impact of the coding scheme was for people to shift to public transport, at least for the day when their vehicle was “coding.” That way, the vehicle is left at home and there is one less vehicle for every person who opted to take public transport. This, however, was not to be and people did not shift to public transport. Perhaps the quality of services available or provided to them were just not acceptable to most people and so they didn’t take public transport and a significant number instead opted for a third way.

That third way to adjust was one that was the least desirable of the consequences of number coding – people who could afford it bought another vehicle. This was actually a result that could have been expected or foreseen given the trends and direct relationship between increases in income associated with economic growth where people would eventually be able to afford to buy a vehicle. Actually, there is no problem with owning a car. The concern is when one uses it and when he opts to travel. Of course, this does not necessarily mean that people started buying new cars outright, making this something like an overnight phenomenon. It happened over several years and involved a cycle that starts when the wealthier people decide to purchase a new vehicle and discards their old ones. These used vehicles become available on the “second hand” market and are purchased by those with smaller budgets. Some of these may have even older vehicles that they will in turn discard, and eventually be owned by other people with even less budget. Note that in this cycle, very few vehicles are actually retired, if at all considering this country has no retirement policy for old vehicles. The end result? More cars on the roads and consequently, more severe and more frequent congestion.

Below is an excerpt from the news report on News TV Channel 11:

Microcosm of society

As me and my colleagues crossed the street at the corner of the College of Engineering towards the Main Library grounds, we heard the distant sound of whistles of security guards posted along the Academic Oval. At first, we didn’t pay much attention even stating among ourselves that the guards may be trying to catch the attention of certain people. There are still many litterbugs on campus and there are street children often going around and trying to collect material they could sell at some junk shop. In some cases, they take whatever they find even those that are not supposed to be taken by them like scrap materials from buildings that are being constructed or renovated. These, after all, are not fair game in as far as the contractors and the university are concerned.

After we had crossed, however, the guards continued to whistle and the frequency and manner seemed to indicate urgency and not just as if they were not just trying to accost someone but were also in pursuit of someone or something. Another guard posted near the library stood up from where he was taking his lunch on a bench under the trees near the road and also started whistling. We soon saw the cause for the alarm – a black BMW 5 series was speeding counterflow along the bicycle lane.

We stopped near the Main Library kiosks to see where the BMW was heading and made our bets that it would be turning left towards the Asian Center and probably towards the exit along Magsaysay Avenue. We were not surprised when the car indeed took a left (and without signals) but towards the driveway in front of Malcolm Hall – the College of Law. I say we were not surprised because there have been many instances before this one when similar vehicles and even those with SUV escorts who have blatantly violated traffic rules and regulations inside the campus. Often, the excuse mentioned is that they were in a hurry. But then aren’t we all?

We did not see who alighted from the car (it was too far to see) but it was parked in front of Malcolm Hall so I assumed it must be a faculty member, a lecturer or a guest of that College who drove or owned the vehicle. It would also be likely that the occupant was a lawyer. This begs the question of what kinds of lawyers are teaching at the College of Law. I know this is quite a generalization and perhaps unfair to many whom I know from that college. But this simple act of violating the one-way scheme along the oval and using a lane dedicated to pedestrians and cyclists despite all the signs and the guards shouting at you, which some people (like lawyers for example) would dismiss as petty are manifestations of more serious things. And I will restrain myself from alleging what those serious things are.

If he or she was a student, then the obvious question is what kind of students do the college have these days? What kinds of lawyers are being bred by the college? And may I dare ask what kind of lawyers have been produced in the past as there are evidences (from the UP Police, the MMDA and other traffic enforcers) that the same professionals are the one most likely to argue with enforcers even when they are guilty of violating traffic rules and regulations.

It is the arrogance of such motorists that is among the common causes of road crashes and the major cause for anarchy and chaos in our roads. The example in UP only shows how far we are from the objective of instilling discipline among our motorists. That same arrogance shows, too, how we regard everyone else including the joggers, walkers, and cyclists who had to give way to a motor vehicle that intruded into their right of way and practically bulldozed its way towards its destination. For these people, it is no matter that they put the lives of people in danger by their actions. After all, they were in a hurry. I believe the pedestrians and cyclists were in no hurry. they were in no hurry to get injured or, God forbid, to die because a motorist in a luxury car had to run against the one-way flow and use road space that is dedicated for pedestrians and cyclists – most of whom happen to be students who have yet to fulfill their potentials, and hopefully for the good of this country.

Tools for traffic enforcement

The MMDA recently acquired speed guns to enable them to measure vehicle speeds and catch violators of speeding regulations. A case in point is the ongoing efforts to reduce road crashes along Commonwealth Avenue in Quezon City. Part of the effort is the enforcement of the 60 kilometer per hour speed limit that is applied to all vehicles. This, of course, is a simplification considering that ideally there are different speed limits for different types of vehicles if Philippine laws are to be reviewed. One problem with Commonwealth is that it is a very wide road with 8 to 10 lanes per direction depending on the section from Fairview to the Elliptical Road. All types of vehicles seem to be guilty of “over-speeding” but of particular concern were and are the buses that also have tended to change lanes quite frequently despite the maneuver being unnecessary.

Most private vehicles are also probably guilty of speeding at many points along the avenue. The wide road is indeed very tempting for cruising at high speeds much like what a driver may routinely do along expressways. The problem, of course, is that the avenue is not an expressway where access is restricted and there are practically no chance or instances of conflicts with pedestrians, vendors or typical public transport operations. And then there are also the ubiquitous median openings that have replaced at-grade intersections. These facilities have encouraged weaving and, arguably, aggressive driving in order to be able to maneuver to the nearest practical U-turn slot.

But going back to the speed guns; these are very handy tools for traffic enforcement. Based on what I saw on TV, the speed guns allow the operator to take a photograph of the guilty party’s vehicle and save this for downloading later at the office. The downloaded photos are then processed into a form (summons) that is sent to the owner of the vehicle who is assumed to be the driver of the vehicle caught by the speed gun’s camera. The person is given 7 days to pay the penalty/fine (PhP 7,500 accroding to the news reports) at the MMDA or at an accredited bank. If the person is unable to pay the fine, the MMDA will forward the violation to the LTO for flagging or tagging of the vehicle used. This tag will serve as an alarm for traffic law enforcers in case the vehicle is involved in another incident.

The speed gun is not an inexpensive tool and yet it is a very useful one if only to instill discipline to drivers in the form of speed management. Speeding is one manifestation of irresponsible or reckless driving, especially when combined with other maneuvers like frequent lane changing. It is also one of the most difficult to enforce since measurements are required and evidence must be strongly tied to a particular vehicle so that the match is “beyond reasonable doubt,” as lawyers may say.

Speed guns like the ones acquired by the MMDA will surely contribute to curbing speeding violations and reducing the incidence of crashes. However, this is currently limited to Commonwealth and there is definitely a need to acquire more instruments to enable the agency to enforce speed limits along other roads including perhaps EDSA and C5. At the very least, speed limits should be enforced along all the radial and circumferential roads. This is particularly important during the night time and probably the early mornings when many road crashes are associated with speeding violations that are obvious for the characteristic loss of control by the driver. The acquisition and proper use of additional units will go a long way into putting order to traffic along our roads and this order can be equated to ensuring that our travel ways will be safe for all users.

Ortigas traffic

Ortigas Avenue traffic is very familiar to me.  For one, I have used the road since childhood because it was the most direct route to and from school. We lived in Cainta and I went to school for 11 years in Mandaluyong. Before that, I even have memories of the section of Ortigas Avenue where Valle Verde phases are now located being carved quite literally from the adobe mountain that it was back in the mid 1970’s.  Ortigas was the only access for those living in the east, particularly the Antipolo-Cainta-Taytay-Binangonan-Angono towsn of Rizal Province, for quite some time. Marcos Highway was still a dirt road and Marikina and Cogeo were somewhat out of the way. Meanwhile, Ortigas was already an important corridor as it led to Antipolo, an important religious and popular recreational site.

As the populations of the Rizal towns I mentioned increased, mostly due to their proximity to Metro Manila and being popular for residential developments then as now, Ortigas became congested. The avenue itself was widened but as any traffic engineering textbook will tell us, the bottlenecks were really the bridges. And I also remember the Rosario Bridge across the Pasig River being widened twice, both before the Manggahan Floodway was constructed. I experienced the impacts of both widening endeavors and did not enjoy having to wake up earlier than when I usually did because of the horrific traffic. It was worse,  I guess, when the Manggahan Floodway was being constructed and there were too few options as to alternative routes. In fact, there were too few bridges across the floodway and Pasig River.

Nowadays, traffic congestion along Ortigas Avenue seem much worse than before. This I get from my siblings who still use the corridor as part of their routes to their workplaces. I trust in their assessment considering that my brother went to the same Mandaluyong school I attended and my sister attended another exclusive school in Pasig. My sister’s husband attests to the worsening traffic as he’s also lived at a residential area along Ortigas. From firsthand observation, I can also validate that Ortigas is worse these days than say 10 and 20 years ago.

The counterflow scheme along Ortigas is not new. In fact, my father and our school service drivers  knew about this and would often time their trips to coincide with the scheme so that they can drive almost continuously to their destinations in the morning. Back then, I remember that the counterflow scheme was in effect for 10 to 15 minutes at the 0630, 0700, 0730 and 0800 times. It was also actually a regulated one-way scheme and was called thus since it benefited vehicles traveling along the outbound (from Rizal) direction. Inbound traffic were stopped at strategic points along the avenue including Rosario Bridge.

Such schemes are possible only when there is a dominant direction during the peak hours. In the case of Ortigas the directional distribution before was practically 90% outbound in the morning peak. A one-way, counterflow scheme was possible and practical for an undivided road. There were no medians or island to prevent vehicles from moving over to the opposing lane and back. That was then and at a time when I suppose that there were less friction along the avenue. Road friction, particularly those caused by public utility vehicles stopping for passengers, is more serious these days as the number of PUVs have also dramatically increased to address the demand for travel. Only now, there seem to be more informal terminals and longer dwell times at strategic points along Ortigas. These cause the bottlenecks that are also complicated by Ortigas now having median barriers along its length.

I believe congestion can be significantly alleviated by developing and implementing a simple dispatching system for PUVs along strategic points like the designated loading and unloading zones at either ends of the Manggahan and Rosario bridges. The dispatching system should be implemented along with a strict enforcement regime to ensure quick boarding and alighting times and prohibiting PUVs from spilling over and occupying other lanes, that often results in blockage of general traffic. Perhaps, a counter-flow scheme may be re-evaluated and become unnecessary. This recommendation comes in the heels of a survey we conducted along Ortigas only yesterday, February 10 in Manila, where I personally experienced PUVs making a terminal out of the outbound lanes before the Manggahan bridge and effectively blocking outbound traffic along the avenue. I can imagine the frustration of those caught in traffic along Ortigas and its implications along the extension and the Imelda and Bonifacio Avenues from Cainta Junction. The result of that blockage and the implementation of a counterflow around 0715 is shown in the following two photos I took.


Figure A: Image downstream along Ortigas Avenue (to Rosario Bridge and C5)

 

Figure B: Image upstream along Ortigas Avenue (from Cainta Junction)

 

It is clear from the photos that private vehicles were the ones who benefited from the counterflow. However, it is interesting to see that the outbound lanes were practically empty especially along the Manggahan Bridge. This clearly shows that there is actually enough road capacity but that it is not utilized (and counterflows were required) because of the blockage caused by PUVs upstream of our position. This is another strong case for going back to the basics in as far as traffic engineering and management is concerned. It does not take a PhD degree to see what’s wrong in the photos and certainly an advanced degree is not required for a solution to the problem.

After focusing on one negative trait, I didn’t expect to be writing immediately about another. Again, I do this in the context of transport and traffic, and to drive home the point that we really need to go back to the basics in as far as solving transport and traffic problems in this country is concerned. Ningas cogon refers to how a type of grass burns when set on fire. There is initially an intense burning of the grass but after a short time it dies out. This behavior of the burning is often alluded to when describing efforts that are not sustained and especially those that showed enthusiasm (and therefore promise) only at the start. It is also associated with an initial show of interest that eventually and shortly wanes for one reason or another.

Only two weeks back I was writing about Commonwealth Avenue and how it was called a killer highway. At the time, I was hopeful that the renewed effort to impose discipline among motorists and especially public utility vehicle drivers and pedestrians would result in a significant improvement of safety along the highway. The initial results seemed to be encouraging, with a dramatic decrease in the number of road crashes and deaths in the first few days. I even had several opportunities to observe the efforts of enforcers, the combination of MMDA, PNP and QC personnel, to keep PUVs along their designated lanes and remind motorists and pedestrians to follow rules and regulations. I was pleasantly surprised, for example, to see vehicles “slow down” to 60 kph instead of the expressway speeds they usually attain along Commonwealth. At the Philcoa area near Commonwealth’s junction with the Elliptical Road, PUVs were being guided through the loading and unloading area and violators were quickly apprehended by MMDA and PNP personnel closely watching the traffic.

Meanwhile, I read a few newspaper columns giving mixed reviews about the program. One column in particular from a major daily mentioned that the effort lasted only a few days and that traffic reverted back to pre-discipline zone times. My reaction was one of disappointment, not for the government but for the columnist whom I thought came up with a premature conclusion, given that changing motorist and pedestrian behavior and attitudes along a major thoroughfare would take time. I did mention though in my previous post that enforcement should be firm and sustained in order for it to be successful and enduring. Also, I was already wary of the tendency for such programs to go the way of others before it – ningas cogon.

Last Sunday, I drove along Commonwealth on my way to visit my in-laws in Novaliches. I decided to do an experiment using a simple method that I learned when I was a student at University and which I also teach my students in undergrad civil engineering. In what is called a floating car technique, I attempted to travel according to the speed limit of 60 kph. I also tried my best to keep my lane, only changing when it was necessary. I also tried to count how many vehicles would pass me, indicating how many traveling my way were faster than me and therefore over-speeding.

The first thing I noticed when I entered Commonwealth from University Avenue was that buses and cars were again zipping by me and so I didn’t bother anymore to count those passing me. I did maintain my speed so I could have a reference as to how fast the other vehicles were relative to mine. Approaching the Fairview Market area, I also observed that people were crossing almost anywhere and that some barriers have been moved to allow jaywalkers to cross the median. Meanwhile, the pedestrian overpasses were all crowded and I could see the entire length also occupied by vendors. Not an enforcer was around to bring order in what was a chaotic marketplace scene – along a major highway.

I repeated the experiment in the afternoon when I drove from my in-laws home to my parents’ home. Taking the opposite direction, Commonwealth was even more congested when I approached the Fairview Market area. Buses, jeepneys and tricycles practically took up 3 lanes, stalls, hawkers and pedestrians took up 2 lanes and there was only 1 left for all other vehicles to pass through. No one among those who clogged the highway seemed to care and I again saw no enforcers to mahage traffic. If there were, I’m sure they were somewhere else and definitely not doing their jobs.

It is both disappointing and frustrating that the traffic discipline program along Commonwealth went the way of ningas cogon. In fact, the MMDA seemed to have celebrated what they thought was success prematurely, even stating that they were to apply similar strategies to other major roads in the Metro. By the looks of the outcomes along Commonwealth, such efforts along other roads will eventually go the way of ningas cogon. Such results send the wrong message to motorists and pedestrians and reinforce the perception that the authorities don’t really mean business and that such programs are just for show. So far, it seems that this perception will continue to pervade along Metro roads unless the MMDA, the PNP and the respective local government units get their acts together. Again, it shows that going back to the basics remain the main challenge and overcoming the ningas cogon tendency the main obstacle for our authorities.
