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.

Discipline along a killer highway

Commonwealth Avenue in Quezon City was given a tag as a killer highway due to the frequent occurrence of road crashes along the road, many of them resulting in fatalities. Only last December, a retired judge was about to cross the highway on his vehicle, his wife (a retired teacher from a prestigious science high school) with him as they were heading to church. It was very early in the morning since they were going to the Simbang Gabi or night mass – a tradition in the Philippines during the Advent Season leading up to Christmas Day. Despite probably signalling and their being cautious enough, their vehicle was hit by a speeding bus. The driver of the bus was to claim later that he used his lights and horns to warn the judge against crossing. There was no mention if the bus driver attempted to slow down, the safest thing to do when driving at night and knowing that there are many crossings along the road he is traversing. In fact, this should be the first thing on the mind of anyone aware and conscious about safe driving.

There are many incidents like the one above and not just along Commonwealth or other Metro Manila road. Road crashes occur along many of our national and local roads everyday and the casualties just pile up, and many are often just treated as statistics especially when nothing is done to address the issue. Such road crashes occur due to many factors that are usually categorized into human, vehicle or environment-related. Most often, as findings in the Philippines indicate, it is the human factor that results in a road crash.

Driver error, poor maintenance of vehicles, and ill-designed roads can all be traced to human shortcomings. Environmental factors are also ultimately rooted on the human element. Speeding is one thing and aggressive driving is probably another but altogether general driver behavior along Philippine roads are clearly a manifestation of a lack of discipline and not necessarily the lack of skill, although the latter is also a significant factor if one is to focus on public transport and trucks.

There are few exceptions and it seems “few” is a relative term often leading to the example of Subic. At Subic, we always wonder how and why drivers seem to be disciplined. Some say it is because of the fines or penalties for traffic violations. Others say it is psychological and a legacy of the base being previously under the US military. I would say it is more of the traffic rules and regulations being enforced firmly and fairly in the free port area. I would add that motorists and pedestrians have embedded this in their consciousness such that there is something like an invisible switch turning on when they drive in Subic and turning off once they are out of the free port.

For a corridor like Commonwealth, perhaps the best example to emulate would be the North Luzon Expressway (NLEX). Along that highway, its operators the Tollways Management Corporation (TMC) have established a strict regimen of enforcement and have applied state of the art tools for both monitoring and apprehension. These tools include high speed cameras equipped with speed radars that detect speeds and capture on photo cases of overspeeding. Photos are used as evidence upon the apprehension of the guilty party at the exit of the expressway.

The current campaign along Commonwealth is premised on the strict enforcement of a 60 kph speed limit along the arterial and the designation of PUV lanes (e.g., yellow lanes) along the length of the corridor. The initiative would be manpower intensive and features novel tools such as the use of placards,  loudspeakers and public relations in order to encourage motorists and pedestrians to follow traffic rules and regulations. The results as of today look promising and there has been a significant reduction in speeds and general compliance for PUVs serving the corridor. The numbers might be misleading if we attempt to conclude about the success of the program now. Perhaps the more reliable statistics would come out after the campaign has been implemented and the effort sustained over a month’s time. Nevertheless, it gives us a nice feeling to see less speeding and less weaving among vehicles that were once observed as though they were driven along a race track. It would be nice to once and for all kill the “killer highway” tag and make Commonwealth an example of how traffic management should be implemented. We are always searching for examples of good if not best practices that can be replicated elsewhere. If we succeed in the “Battle of Commonwealth” then perhaps we could eventually win the “War Against Irresponsible Driving and Jaywalking.”

Traffic discipline and technology

In a recent post entitled Replicating success, I stated that the challenge for the government is to replicate the success of the campaign against wangwang or the illegal use of sirens. I indicate a short list of four items that I wished would be part of a Top Ten list of road traffic rules violated by motorists and pedestrians. Perhaps the list should include swerving and aggressive lane changing. Maybe even add to that tailgating and beating both green and red lights at the intersections.

The point is that there are just so many rules and regulations that are ignored by motorists and pedestrians who are used to lax traffic enforcement with the exception of perhaps only a few places in this country. These few places include Subic and for a time, Bonifacio Global City. In 2007, UP Diliman and its partners from the private sector led by the Automobile Association Philippines (AAP) and Toyota established a model traffic safety zone in the campus, focusing on the Academic Oval. The initiative included the introduction of traffic schemes such as a one-way counter-clockwise circulation for the oval, and the installation of standard traffic signs and road markings. Training was also provided to the university police force as well as to the traffic enforcers deployed around the oval.

Even without traffic tickets to issue to violators, the university was successful to some degree in enforcing traffic rules and regulations, particularly apprehending and firmly reminding motorists about traffic rules inside the campus. Constituents were also made aware of the issues pertaining to road safety and many stakeholders like students and staff contributed with some even stopping counterflowing vehicles and turning them back despite resistance and even arrogance and profanity in some cases. In most cases, motorists guilty of violating traffic rules and regulations were not even constituents of the university though some claimed to be alumni or relatives of students. These included drivers of vehicles with red plates (indicating they were government vehicles) and young motorists who seem to fit what some people would like to define as stereotypes of people likely to ignore rules. However, it took UP Diliman 3 years to achieve this level of discipline in its roads and there are still many complaints, primarily directed at jeepney drivers who seem to be quite hardheaded when it came to changing their driving behaviors (and habits). Subic was not an overnight success either and yet motorists seem to change when they enter the former military base’s gates and drive along its streets.

The question now is whether wangwang is just a fluke, a lucky punch in boxing parlance. Our enforcement agencies are often accused of being ningas cogon, a common practice where enthusiasm and activity is present only at the start but rapidly wanes as time passes by, much like how grass burns strongly at first but fizzles out later. Surely, this is not a case of sustainable traffic management.

The challenge, therefore, is still on sustainability but also and always building capacity to be firm and consistent with enforcing traffic rules and regulations. Such includes the use of emerging technologies that enable non-contact apprehension (and the MMDA is right on in this aspect) but should also lead to more aggressive campaigns to ensure public awareness and comprehension that they are being monitored. But more than this, it should be emphasized that those monitoring should be competent and fair in their observations such that non-contact apprehension will succeed and will not be subject to ridicule by a knowledgeable public who are already wary of abuses by government. It is very important that at this stage when IT is being introduced to enhance traffic management including public transport and logistics, that technology is not misconstrued as invasive and a tool for corruption. That way, we can move forward and perhaps, in the near future, enable intelligent transport systems to enhance traffic and safety in our roads.

Replicating success

In his inaugural speech, P-Noy stated his disdain for “wang-wang,” referring to the abusive of the sirens by certain people. “Wang-wang” then symbolized how these people practically claimed privilege over other people haplessly caught in traffic jams. The mere reference to “wang-wang” and the marching orders for the PNP-HPG and the LTO to crack down on the abuse led to an aggressive, fast and effective campaign that resulted in the confiscation of illegal sirens. In effect, the campaign brought back the sirens to its original purpose. And that is to get the attention of motorists for them to give way to emergency vehicles such as ambulances and fire trucks.

I’ve always wondered after that successful campaign why our agencies can’t replicate this for other traffic violations as well. Surely, a similar campaign will go along way in establishing firm enforcement of traffic rules and regulations – something that has been cited time and again as what needs to be done to bring order to the traffic mess we experience everyday.

Perhaps we can start off by listing something like a Top Ten rules that are violated and apply the “wang-wang” campaign to these. I nominate the following to be included in the Top Ten:
1. Counterflowing
2. Use of illegal license plates
3. Speeding
4. Jaywalking

These combined with another aggressive campaign but this time on the environment side (i.e., no-nonsense emission testing and anti-smoke belching) should help ease traffic in many major thoroughfares. These could all be under the banner of a Traffic Discipline Zone (TDZ) or corridor and if implemented properly may help bring respect back to our traffic enforcers. I am optimistic that enforcement will go beyond just being a motherhood statement and that its contributions would be very significant.

Odd-Even Now? (Conclusion)

From the previous posts, it is clear that vehicle restraint measures can very effective in reducing congestion. However, there are also obvious limitations to the effectiveness of these schemes. In the case of the UVVRP, this limitation has been reached considering that the Philippines and Metro Manila in particular continues to experience a high rate of motorization. This is partly explained by a general increase in car ownerships that have resulted in increased traffic volumes in our roads. It is not surprising that people who can afford more than one vehicle often choose vehicles with license plates ending in numbers that will ensure they can take at least one car everyday. In many other cases, motorists have adjusted their schedules so that they can take their cars during days when the vehicles are prohibited during “coding” hours. Given such circumstances, the Odd-Even scheme will ultimately reach its limit and will be most effective for the short -term, especially since it is expected to take a lot of flak if not examined and implemented properly.

In conclusion, I reproduce below excerpts of my letter to one Metro Manila mayor prior to his attendance of the Metro Manila Council meeting where Metro Manila mayors took up the proposal by the MMDA to implement the Odd-Even scheme along EDSA.


“The papers tackle various traffic schemes implemented in Metro Manila and focuses on the impacts and effectiveness of the UVVRP (Unified Vehicular Volume Reduction Program or number coding) in particular. Unfortunately, at the time the studies did not include evaluation of the Odd-Even scheme although such is mentioned in the first paper as the precursor of the UVVRP. Please note that these schemes are classified among vehicle restraint options that include the truck ban. Color-coding, number coding and the odd-even schemes were originally implemented as short term measures intended to be modified or lifted once the infrastructure projects that were then being implemented (overpasses and underpasses, coordinated and adaptive traffic signals, etc.) were completed. The UVVRP was indeed modified to include a window from 10:00AM – 3:00PM. Meanwhile, some LGUs in the periphery of Metro Manila no longer implement the UVVRP since they do not have much congestion unlike those LGUs where traffic converge along major thoroughfares such as EDSA, C5, C3, Gil Puyat, Espans and Quezon Ave. and Commonwealth. Incidentally, many of these roads are found in Quezon City.

The perceptions on the potential negative impacts of an Odd-Even scheme for EDSA are well founded since vehicles displaced will naturally be diverted to other roads. We have to be careful though not to call such roads simply as side streets or alternate routes since C5 (Katipunan (in QC)-E. Rodriquez (Pasig)-CP Garcia (Makati-Taguig), C3 (Araneta Ave.), Shaw Boulevard, Quezon Avenue and others are major arterials and form part of the circumferential and radial road system of Metro Manila. We are to expect more congestion along these roads that will, in effect, marginalize potential gains along EDSA.

The recommendation therefore, is for the MMDA not to experiment on EDSA from November 2010 to January 2011 but instead undertake in-depth analysis of the implementation of an Odd-Even scheme. Direct experimentation while effective in some cases will without doubt place much of the burden on the people using EDSA and other major roads. It is known that MMDA has acquired the capacity to simulate traffic based on their recent presentations. Perhaps this should be done for the entire stretch of EDSA and include all major roads affected considering that they will bear traffic diverted from EDSA. Such traffic simulation should, however, be properly calibrated and validated to reflect real world conditions. This is because it is also easy to come up with simulations whose results are partial or biased on what the simulator wants to show.”


Should the MMDA choose to go the way of vehicle restraint and examine the benefits and costs of implementing the Odd-Even scheme as well as revisit the UVVRP and truck ban, it is recommended that they also study other vehicle restraint measures in combination with schemes favoring public over private transport. In fact, government should take the lead in encouraging a shift to public transport use in parallel with efforts to improve the quality of service of public transportation in Metro Manila. Perhaps it is time to revive discussions on congestion pricing and take the cue from the example provided by Singapore. It is worthwhile to learn from their experiences that we so often dismiss as exceptions yet are actually textbook applications that met with success due to a mix of political will and a citizenry who cooperated because they understood they had no choice if they were to improve transport and traffic conditions in their city-state. Perhaps we should realize the same while lobbying our government and public transport service providers for the transport system that we deserve in order for us to move forward in progress.

Truck Ban

Another form of vehicle restraint focuses on freight and logistics vehicles, particularly trucks. These are commonly referred to as large vehicles having at least 6 tires (double-tired rear axle). The prevailing perception is that many if not most of these vehicles are overloaded and impede the flow of traffic due to their slow speeds as well as damage pavements not designed for heavy vehicles.

“The truck ban is a scheme first applied in the late 1970’s to address the perception that freight vehicles are the main culprits in congesting Metro Manila roads. Trucks were prohibited from traveling along major arterials including the primary circumferential and radial road network for most of the day. Exemptions from the daytime ban were applied to roads in the vicinity of the port area where truck traffic was practically inevitable.”

The coverage area of the truck ban included all of Metro Manila’s major circumferential and radial roads – C1 to C5 refer to Metro Manila’s circumferential roads while R1 to R10 refer to the radial roads. These comprise the main arterials of the Metro Manila road network. For reference, C3 refers to Araneta Avenue and related roads, C4 is EDSA, Letre and Samson Roads, and C5 refers to Katipunan, E. Rodriguez and C.P. Garcia Avenues. R1 refers to Roxas Boulevard, R5 is Shaw Boulevard, R6 is Aurora Boulevard, and R7 is España and Quezon Avenues.

“There are the different versions of the truck ban being implemented in Metro Manila. Truck Ban 1 is enforced along EDSA, Metro Manila’s busiest arterial and often its most congested road. Designated as Circumferential Road 4 (C4) it has a 10- to 12-lane carriageway with a mass rapid transit line running along its median. Truck Ban 2 practically covers all other roads except sections of arterial roads that have been designated as truck routes.”

Truck Ban 1 is enforced from 6:00 AM to 9:00 PM everyday except Sundays and Holidays. Meanwhile, Truck Ban 2 is implemented from 6:00 AM to 9:00 AM and 5:00 PM to 9:00 PM everyday except Sundays and Holidays. The second version attempts to minimize trucks during the morning and afternoon/evening peak periods.

“The chronology of the truck ban scheme started in 1978. In recognition of the critical situation of traffic congestion in Metro Manila, the then Metropolitan Manila Authority (MMA) issued Ordinance No. 78-04, which prohibited cargo trucks, with gross vehicular weight (GVW) of more than 4,000 kilogram, from plying along eleven major thoroughfares in Metro Manila during peak traffic hours – from 6:00 A.M. to 9:00 A.M. and from 4:00 P.M. to 8:00 P.M., daily except on Saturdays, Sundays and holidays.

In 1990, the Department of Transportation and Communication (DOTC) issued Memorandum Circulars No. 90-367 and 90-375, changing truck ban hours to: between 7:00 A.M. and 10:00 A.M. on weekdays; 4:00 P.M. to 8:00 P.M. for Monday to Thursday; and from 4:00 P.M. to 9:00 P.M. on Fridays. In response to the appeal of the members and officers of the various truckers’ associations for an alternate route and a 2-hour reduction of truck ban, the MMA issued Ordinance No.  19, Series of 1991, amending MMC Ordinance No. 78-04.  This issuance provided alternate routes to the truck ban routes and effected a 2-hour reduction of the truck ban period, thereby prohibiting trucks on the road from 7:00 A.M. to 9:00 A.M. and from 5:00 P.M. to 8:00 P.M.

In 1994 the MMA issued Ordinance No. 5, Series of 1994, further amending Ordinance No. 78-04 as amended by Ordinance No. 19 Series 1991.  The Ordinance restricts trucks from traveling or passing along 10 major routes from 6:00 A.M. to 9:00 A.M. and from 5:00 P.M. to 9:00 P.M. daily, except on Saturdays, Sundays and holidays.  The Ordinance also provided for an “all-day” truck ban along Metro Manila’s major arterial road, the Epifanio Delos Santos Avenue (EDSA), from 6:00 A.M. to 9:00 P.M. daily, except Saturdays, Sundays and holidays.

In 1996, the MMDA, in its desire to further reduce traffic congestion even on Saturdays, issued Regulation No. 96-008 amending MMA Ordinance No. 94-05, imposing truck ban from Monday to Saturday, except Sunday and holidays. An MMDA Regulation No. 99-002, amended Ordinance No. 5, Series of 1994, wherein the “gross capacity weight” was amended from 4,000 to 4,500 kilograms.”

In the last few years, the MMDA has implemented adjustments to the truck ban scheme in coordination with Metro Manila local government units. Certain truck routes were identified to address the issues raised by the private sector, particularly industries and commercial establishments, regarding the transport and delivery of goods. Other cities in the Philippines have adopted the truck ban in one form or another, often directing trucks to use alternate roads in order to decongest the roads in the central business districts as well as to prevent their early deterioration as a result of truck overloading practices.

From Odd-Even to UVVRP… and back

Picking up from where I left off in the last post, I reproduce another part of the paper I co-authored with a good friend who now happens to be the Director of the Center for Policy and Executive Development (CPED) of the National College of Public Administration and Governance (NCPAG) of UP Diliman.

“The UVVRP or the “number coding” scheme, as it is commonly called, is a travel demand management measure that has evolved since its first implementation in 1995. The original intent was to use this measure to address congestion brought about in part by the many road and rail infrastructure projects being implemented throughout Metro Manila in the 1990’s. However, due to its perceived success in decreasing traffic along Metro Manila arterials, the scheme’s implementation was extended and even expanded to include public transport vehicles like buses, jeepneys and taxis.

The original programs involved only the main arterials of Metro Manila including its five circumferential and ten radial roads. These included the three expressways that connected the region to surrounding provinces in the north and south. All these are classified as national roads. The current program includes essentially all roads, with traffic enforcement units of cities and municipalities implementing the scheme for city and municipal roads. The MMDA enforces the scheme along most major roads.

The chronology of the development of UVVRP starts in 1995 when the MMDA Regulation No. 95-001 otherwise known as the “Odd-Even Scheme” was issued. The scheme bans private vehicles with less than three (3) occupants from plying restricted thoroughfares during AM and PM peak periods on particular days. Specifically, low occupancy private vehicles with license plates ending in odd numbers are banned on Tuesdays, Thursdays and Saturdays, while those with license plates ending in even numbers are banned on Mondays, Wednesdays and Fridays. Peak period is defined to be between 7:00 AM to 9:00 AM and 5:00 PM to 7:00 PM. The penalty was set at P 300 per offense. Exempted from this regulation are public transport vehicles, emergency vehicles, police and military vehicles, school buses, diplomatic vehicles and official media vehicles.

In 1996, the MMDA issued Regulation 96-004 otherwise known as the “Modified Odd-Even Scheme” in addition to the existing Odd-Even Scheme. The Modified Odd-Even scheme applied to public utility vehicles such as taxis, buses, public utility jeepneys, etc., which are banned from all streets of Metro Manila on particular days of the week from 9:00 AM to 5:00 PM based on the plate number ending of each vehicle, as follows: 1 and 2 on Mondays, 3 and 4 on Tuesdays, 5 and 6 on Wednesdays, 7 and 8 on Thursdays, 9 and 0 on Fridays. This regulation took effect February 19, 1996 and covered all roads in Metropolitan Manila.

Also, in 1996 the Metro Manila Council, MMDA, adopted and promulgated MMDA Regulation 96-005 entitled the “Unified Vehicular Volume Reduction Program” regulating the operation of certain motor vehicles on all national, city and municipal roads in Metropolitan Manila and repealed MMDA Regulation Nos. 95-001 and 96-004. The UVVRP, commonly referred to as “color-coding”, was adopted from the previous “Odd-Even” scheme which was first implemented in December 1, 1995 by the MMDA together with the Philippine National Police.  Under this scheme both public and private vehicles are banned for longer hours (i.e., between 7:00 AM and 7:00 PM).  This regulation was first implemented last June 1, 1996 and is still in effect.

In early 2003, the MMDA temporarily suspended the UVVRP. The resulting mayhem, probably due to the abrupt reaction of car-users, forced the MMDA to restore the scheme. A variant of the scheme was later introduced with a window from 10:00 AM to 3:00 PM (i.e., the off-peak period within the day) when banned vehicles may travel. Not all cities and municipalities in Metro Manila, however, adopted the scheme due to its perceived detrimental effects on traffic in their respective areas. The prime central business districts of Makati and Mandaluyong prompted these cities to implement the UVVRP from 7:00 A.M. to 7:00 P.M. This created problems as many roads run through different cities and municipalities, especially the circumferential and radial roads. Thus, it is possible for a motorist to use his vehicle in a city adopting the off-peak period window and get apprehended in another city that enforced the UVVRP during the daytime.”

I am aware of certain stories circulating among those in the transportation and traffic circle(s) claiming an even earlier concept of the Odd-Even scheme. All stories seem to eventually lead to Oscar Orbos who had a brief stint as Secretary of the Department of Transportation and Communications (DOTC) in the Cabinet of Cory Aquino in 1990. He is, of course, credited with the conceptualization and implementation of the “yellow lane” scheme, as lanes alloted for exclusive use of public utility vehicles have come to be known. An earlier version of the Odd-Even scheme has been attributed to him and, perhaps subject to verification, was claimed as among the reasons he was eventually relieved and transferred to another post. I say subject to verification because I do remember but faintly that there was a lot of talk about how to drastically lessen the number of vehicles along Metro Manila roads at the time. I was quite naive to such being a college junior at the time and was quite indifferent to policies that years later I would be evaluating and writing about. Moreover, it has been established that certain stories if allowed to circulate long enough gains the appearance of being true.

At this point, I am already tempted to provide a brief conclusion on the lessons and experience of vehicle restraint policies as implemented in Metro Manila. However, I would have to defer until after another post where the topic will be another vehicle restraint scheme, this time one that is even older than the UVVRP and its various incarnations. It is a scheme that has been subject to probably even more discussions and scrutiny given that it is a scheme other cities have implemented in various forms and had its share of successes and failures. I am talking about the “truck ban.”

Wang wang!

In the inaugural speech of Philippine President Noynoy Aquino, I and my colleagues were pleasantly surprised hearing him start with an item considered to be a pet peeve among multitudes of Filipinos – the use of sirens and blinkers. In fact, the reference to sirens as “wang-wang” puts it in the proper context where use is actually abuse. The “wang-wang” has been a symbol of how many of our government officials as well as those who perceive themselves as entitled have abused our traffic systems to get their way at the expense of others that they seem to believe have much lesser values of time compared to theirs.

Many who have been forced to surrender their sirens and blinkers state various reasons for doing so, including being professionals who needed to be in certain places at certain times. Among these are medical doctors and lawyers who have always claimed to be in a hurry, in the process of addressing emergencies of both the real and the imagined kind. While there are other opposing views on this, I firmly believe that the same people totally missed the point regarding the new president’s stand against “wang-wang” and his current personal crusade against beating the red light, counter-flowing, and the use of sirens by his own presidential convoy.

The statement should be pretty clear that only emergency vehicles may use sirens especially because they are responding to matters of life and death. These include ambulances, fire trucks and official police vehicles that should have distinct sounds according to international standards. The distinction is important for people to be able to recognize what type of vehicle is attempting to come through. But more importantly, the statement is also to show everyone, whatever his place in society may be, that the days of abuse are past and that this administration will do its part to bring back decency in our roads starting with the drive against “wang-wangs.” It is also actually an excellent case for leading by example, and one that hopefully can be sustained by P-Noy and adopted by his officials. For our part, we should make our own contributions and practice more discipline when we drive, commute or even walk along the street. It is not an exercise in futility but rather an exercise in humility and productivity – a demonstration of our commitment to change and help this country become great again.
