Road crashes in Antipolo
I open June with a post on road safety. Last week, I passed by many road crash scenes along my route between my home in Antipolo and my office in Quezon City. Many were the now common crashes involving motorcycles. And there were those involving vehicles that got too close to each other in heavy traffic (e.g., tailgating vehicles eventually bumping the vehicle ahead of them). I was able to get photos of the site of the more serious crashes.
Head on collision of a car and owner-type jeepney along Marcos Highway near the junction with Amb. Neri Road. These crashes are largely preventable if drivers kept to their lanes and refrained from violating the rule of the double yellow line separating opposing flows of traffic. I’ve written about counter flowing before but focused on it leading to traffic congestion. A more serious repercussion would be crashes like this.
Overturned passenger jeepney along Marcos Highway in Mambugan, Antipolo. Speeding and unnecessary manoeuvres along this highway often has led to drivers losing control of their vehicles and, in this case, the vehicle turning over and likely hurting (hopefully not killing) passengers. This is again a very preventable crash considering it can be addressed by proper (read: safe) driving as well as enforcement.
Final ‘resting place’ of a truck that apparently lost control along the Tikling bound side of Ortigas Ave. Extension in Barangay Dolores, Taytay. I’ve noticed many breakdowns and crashes involving trucks along this highway as well as Sumulong Highway and Marcos Highway. Many, it seems, involve poor maintenance of these vehicles as well as overloading. Poorly maintained vehicles may lose control with or without their loads and lead to such crashes that in many cases are fatal to innocent bystanders.
With the onset of the rainy season, many roads will be slippery and this will tend to make them more dangerous. In the cases I mentioned above, most crashes are not the fault of the roads or the infrastructure but of the drivers and/or operators of the vehicles. Most crashes are preventable and are caused by driver error, negligence or aggressive behaviour. It is often the nut behind the wheel who is responsible for such crashes rather than the vehicle or the road.

Will a flyover at Katipunan-C.P. Garcia solve the traffic problem in the area?
I read a news article about the proposal by the Department of Public Works and Highways (DPWH) to construct a left-turn flyover at the intersection of Katipunan Avenue (C5) and C.P. Garcia Avenue in Quezon City. The flyover is supposed to be for vehicles turning left from the northbound side of Katipunan to C.P. Garcia Ave., which goes through the University of the Philippines Diliman
Will the flyover solve the traffic congestion problem in the area, particularly at the intersection and Katipunan in general? I would say no, it would not solve the congestion problem both for the intersection and for Katipunan. This assessment is due to the following reasons:
- The overpass does not address the root cause of congestion in the area, which is trip generation related. There are many major trip generators along Katipunan alone including three major schools (UP, Ateneo and Miriam) and a mall (UP Town Center). Add to this the traffic generated by the high density residential developments along Katipunan (notice the high rise condominiums lining up across Ateneo and Miriam?) and the through traffic coming from various areas that use C5’s Katipunan section.
- Congestion is caused by saturated intersections corresponding to Ateneo Gate 3 and main gate of Miriam College. Traffic going in and out of these schools are favored over through traffic along C5 resulting in congestion in the area. Perhaps it would be more appropriate to build overpasses to bypass these intersections.
- Congestion is caused by vehicles bound for and coming from the UP Town Center. The congestion due to traffic generated by the commercial development is actually alarming considering it is not yet completed and trips attracted and produced is not yet at full potential.
- The heaviest flows at the Katipunan-C.P. Garcia intersection are along Katipunan (northbound and southbound through traffic). Logic and traffic engineering principles point to grade separation to be more appropriate for such traffic and NOT for the left turn movement. A flyover should also be able to bypass UP Town Center as vehicles bound for the mall already blocks traffic along both sides of Katipunan and directly affects the intersection.
I think the DPWH should do well to re-assess their proposal along the lines of the reasons I have listed here rather than continue with the folly of building a left turn overpass alone. UP Diliman should also resist this overpass as, based on the news article, it would mean UP giving up some 8,000 square meters of its property for the project. UP already has given a lot for widening C.P. Garcia but that goes without saying that a through flyover might also require UP to give up property and particularly from its National Science Complex for such a project.

Some interesting (and required) readings on traffic engineering
Christmas breaks allow me to catch up on a lot of reading. The previous months comprising our university’s semester were spent preparing for lectures though I had to do some readings related to researches I am involved in. Browsing the net and social media, I came across 2 articles shared by an acquaintance. He is a very progressive planner who has extensively studied and written about the most relevant issues in urban planning, focusing on transport. A third article I found while reading one of the two. These were very interesting for me in part because they are thought provoking in as far as traffic engineering is concerned.
- What traffic engineers can learn from doctors
- As traffic deaths rise, blame engineering dogma
- The new science of traffic engineering
The author seems to call out traffic engineers in general but these articles should also be contextualized properly. The situations mentioned in the articles are to be found in cities in the United States and may not be applicable in other cities in other countries. Traffic engineers in Europe, for example, have been working on exactly the solutions being mentioned in the articles that would make streets inclusive and safe especially for pedestrians and cyclists. The same with Asian cities like Singapore and Tokyo.
In the Philippines, however, there is so much that we can learn from the articles. The mere mention of the design guidelines being used in the US betrays the flaws of highway and traffic engineering in the Philippines. The Philippines’ highway planning manual and other guidelines used by the Department of Public Works and Highways (DPWH) are heavily drawn from US references. Most highway and traffic engineers in the country are educated using curricula that use US textbooks and references. There are even civil engineering programs that use licensure exam review materials as their references! These exam materials are also known to be based on DPWH guidelines and manuals aside from problems “outsourced” or patterned after the Professional Engineer (PE) exams in the US. Few schools have progressive curricula that look to best practices that take into account the complexities of roads especially in the urban setting. Such ‘copying’ of American standards and practices in many cases do not consider Philippine (local) conditions and blind applications to our roads instead of proper adaptation often have lead to unsafe and inequitable roads.

Differences: pro-walking vs. anti-car
I came across this article posted at the Planetizen site entitled Pro-Walking, or Anti-Car. It is a good article that heads-on addresses the the differences of being pro-walking to that of being anti-car in terms of transport policies in cities. I think these concepts including the “nuts to crack” list provided by the author is relevant not only to cities that want to promote walking and cycling over car use, but to individuals and groups as well who seem to be following a hard line when in comes to their advocacy to recover road space in favor of pedestrians and cyclists.
Unprepared and incomplete – realizations from the APEC transport experience
Before I forget about what transpired during the holding of APEC in Manila a week ago, here’s a couple of photos I found over the internet and shared via social media.
Commuters along Roxas Boulevard walk past a column of the unfinished NAIA Expressway, one of the transport infrastructure projects that has not been finished. [Photo from The Manila Bulletin]
APEC lanes and severe traffic congestion along EDSA – there’s an opportunity here for a prrof of concept test for BRT. [Photo from Facebook]
I saw many memes and read some articles mentioning BRT specifically as one solution to Metro Manila’s transport problems. The second photo above was modified to replace the car travelling along the APEC lanes with a bus.
It is easy to imagine what could have been if the government decided to use the event and the lanes they allocated for APEC vehicles to do a ‘proof of concept’ run of BRT services or at least express bus services (what some DOTC people call high quality bus services). Perhaps what could have been done for part of the 10 billion PHP expended for APEC was to buy a fleet of brand new buses and provided these for free public transport for people who would need to commute during APEC. Services along two corridors would have sufficed – these two would have been EDSA and Roxas Boulevard. [The other option would have been to talk to bus operators and cooperate with them to organize express bus services along EDSA and Roxas Blvd.] Aggressively promoting these free services ahead of APEC would also have meant commuters, including those who usually used their own vehicles, could have opted for these transport services and not affected by the ‘carmageddon’ that ensued over that period. There should have been services to the airport terminals, too, but I will write about this in another article.
The dry run could have yielded essential data for assessing the feasibility of such bus services as an alternate to rail systems that would take much time to build. Incidentally, if the LRT Line 1 Extension to Cavite was built right after the current administration took over, that line could have already served tens of thousands of passengers from the south who regularly commuted to Metro Manila for work and school. The first photo above does not lie about just how many people could have benefited from that rail project. Meanwhile, MRT Line 3 remains dysfunctional and with its reduced capacity could not handle the demand for transport that it should have been able to carry if services had not deteriorated over the years.

On the Ortigas Avenue counter-flow scheme again
Here are some more recent photos of the morning traffic congestion and counter-flow scheme along Ortigas Avenue. The counterflow scheme starts at the approach to the Manggahan Channel Bridge and ends at the approach to C-5 right after the Rosario Bridge. This counter-flow scheme has been used by Pasig, as far as I can remember, since the early 1980s. Ortigas Avenue is one of those roads where the directional distribution of traffic very pronounced for the peak direction.
Vehicles crowding towards the counter-flow lane on the eastbound side of Ortigas Avenue. Traffic along this lane is moving, unlike the standstill you will likely experience along the westbound side. This is particularly true at the bridge where buses and jeepneys occupy two lanes and stop for long periods to get passengers. Congestion is exacerbated by vehicles coming out of the residential development in the area. Pasig and MMDA traffic enforcers fail miserably at their duties here. Perhaps this is a job for the PNP-HPG?
The effort of positioning towards the counter-flow lane is worth it as traffic moves faster here. The argument for counter-flow lanes (or zipper lanes as they are also called) is based on the availability of capacity along traffic lanes of the opposing direction that can be used to optimize utility of these unused lanes (i.e., off-peak direction) by peak traffic. This is a classic transport systems management scheme directed towards efficient and optimum use of existing facilities.

Proposals for EDSA and some alternate roads
The hellish traffic congestion along EDSA and other roads in Metro Manila spawned a bunch of ideas for alleviating congestion. Among those that were offered as solutions are the following:
- Odd-Even Scheme – suggested by the Philippines President himself in a speech delivered in Mandaluyong City
- Car-pooling (and HOV lanes) – suggested by the DPWH Secretary in another forum
- Bus Rapid Transit (BRT) and/or express bus – proposed and being studied by the DOTC
What seems to have been forgotten was a proposal to have two lanes of EDSA, one on either direction, devoted to bicycles. This proposal now seems to be the most viable compared to the above three and could have the potential for major behaviour change towards a departure from motor vehicle use. Cycling along with walking does not require fuel and these modes also promote healthy lifestyles. Also, this could become the ultimate example for road diets, which can also be applied along other roads as well. What sounds or reads like an outrageous idea (i.e., bicycle lanes along EDSA) might just be revolutionary and result in what could be a tipping point for sustainable transport in the midst of traffic mayhem.
EDSA has become the proverbial battleground representing the war with traffic congestion. However, EDSA is just one part of our arterial network comprised of circumferential and radial roads. There is also C-5 (also known for its sections – Katipunan, E. Rodriguez, C.P. Garcia), which is also a very congested road but along which there are few fixed route public transport services. It is a primary alternative route (to EDSA)for people traveling between the northern and southern halves of Metro Manila. It also serves as a collector and distributor, being connected with major radial roads like Aurora Boulevard, Ortigas Avenue and Shaw Boulevard as well as to the South Luzon Expressway. C-5 is a major truck route, however, and so carries a lot of heavy vehicles during the permitted times under the truck ban scheme being implemented in Metro Manila. C-5 is already ripe for a mass transit system and should have one along it. The quickest to put up would be a bus system on exclusive lanes. Strategically though, a rail transit line (likely elevated) should already be planned and implemented and with as seamless as possible connections to current and future lines along major corridors.
There are other routes that can be considered which I think have been overlooked (too much focus on EDSA?). C-6, for example, badly needs to be improved and this has started but is being implemented at a slow pace. This could have significant positive impacts on traffic coming from the east (towns of Rizal province) that are bound primarily for Makati and BGC. But then there also has to be a good road bypassing the narrow and already congested streets of Taguig and Pateros that are currently the only roads connecting C-5 and C-6. The roads on the Rizal side (attention: Cainta and Taytay) also need to be improved including Highway 2000 and the Barkadahan Bridge. Perhaps the Rizal Provincial Government should also get involved in this as such routes are in the best interest of Rizalenos. And then there is also the highly urbanized city of Antipolo that is a major destination and already is the 7th most populous city in the country, whose residents also use this route, which is often a faster option to Ortigas and C-5 despite the poor conditions of roads.

Local papers presented at the EASTS 2015 conference – De La Salle University
De La Salle University (DLSU) has a strong program in transportation engineering and planning. This program is under its Department of Civil Engineering and led by Dr Alexis Fillone. Following is a list of papers from DLSU:
- Mode Shift Behavior of Bus Passengers to Rail System under Improved Rail Conditions [Alexis Fillone & Germaine Ann Dilay]
- Evaluating Proposed Transportation infrastructure Projects in Metro Manila using the Transport Co-Benefit Analysis [Alexis Fillone]
- Inter-Island Travel Mode Choice Analysis: Western Visayas Region, Philippines [Nicanor Roxas Jr & Alexis Fillone]
- Revisiting Volume-Delay-Functions Used in Transport Studies in Metro Manila [Jiaan Regis Gesalem & Alexis Fillone]
- Characterizing Bus Passenger Demand along Epifanio de los Santos Avenue (EDSA), Metro Manila [Sean Johnlee Ting, Kervin Joshua Lucas & Alexis Fillone]
- Optimized Bus Schedules in Epifanio Delos Santos Avenue (EDSA), Metro Manila Using Fuzzy Rule-Based System [Alexis Fillone, Elmer Dadios & Ramon Intal]
- Opinion Survey about Pedestrianization of Heritage Sites in the City of Iloilo, Philippines [Alexis Fillone & Frederick Sosuan]
- Factors Influencing Footbridge Usage Along Epifanio Delos Santos Avenue (EDSA), Metro Manila [Aaron King, Rigel Cadag, Jireh Despabiladeras, Rei Tumambing & Alexis Fillone]
- A Compact Scheduling and Revenue Estimation Spreadsheet for Bus Operators [Raymund Abad & Alexis Fillone]
- Adaptive Driving Route of Busses along Epifanio de los Santos Avenue (EDSA), Metro Manila, using Fuzzy Logic [Alexis Fillone, Bernard Yasay & Elmer Dadios]
I thought DLSU could have published more papers in this conference. I was actually surprised that all the papers are practically attributed to Dr Fillone considering his co-authors are mostly his students. But then there are only 2 to 3 faculty members who are doing transport research in DLSU and Dr Fillone is the most involved and prolific among them in terms of published research outputs.

Presentations at Usad EDSA consultation, Sept. 24, 2015
Following are presentation materials from the Usad EDSA consultation held at the GT Toyota Asian Center Auditorium of UP Diliman yesterday. I assume these are all for public consumption and for sharing among all stakeholders (all of us traveling in Metro Manila whether we use EDSA or not).
Situationer and actions: 09242015 SRDA EDC_rev
DOTC Express Bus Project: DOTC – Final Expanding Express Bus Services–EDSA Decongestion 24 Sept 2015
DPWH Road Engineering Projects: DPWH
MMDA presentation of situation and data: MMDA-Katupunan Mtg
I will refrain from making comments in this post as I need to understand the contents of the materials first. The important thins is to note that the government is doing what seems to be a best effort given the constraint of resources and time (The Presidential elections are coming up in May 2016.). Everyone of us must pitch in and do our part in making our commutes more pleasant than what they are now.

Consultation on EDSA decongestion – September 24, 2015
There will be a public consultation tomorrow entitled “EDSA Decongestion Consultation” at the GT Toyota Auditorium at the Asian Center of the University of the Philippines Diliman from 1:30 – 3:30PM. The consultation will tackle transport and traffic in Metro Manila but particularly along EDSA. The consultation will be facilitated by the TWG headed by Sec. Almendras who is the cabinet secretary put in-charge of addressing (solving?) the traffic mess in Metro Manila. The TWG includes DPWH, DOTC, DTI, MMDA, LTO, LTFRB, and the PNP-HPG.
This would be a good venue for stakeholders to articulate their concerns as well as offer their ideas towards alleviating transport and traffic problems. Invitations are supposed to have been extended to academic institutions, transport groups and other interested parties. Hopefully, this event will be a productive and constructive one. Pointing fingers and playing the blame game will not get us anywhere.

Caught (up) in traffic
