I’m sharing this article on phantom traffic jams:

Have you wondered why the road or path is congested only to find out there seems to be nothing causing it? This is the phantom or ghost traffic jams caused by simple behaviours of travellers whether on motor vehicles, cycles or people like slowing down their movement or changing lanes. These disruptions cause a “ripple effect” on the traffic stream much as like waves are generated by a stimulus on calm waters.
Here are two interesting (to me at least) articles about the negative aspects of ride hailing or ride sharing. The first is quite a curious one for me as I teach at UP Diliman, which has a sprawling campus in Quezon City. Students can have one class at a building on one end of the campus and have the next class at another end of the campus. I now wonder if there’s a significant number of Grab or Angkas trips within campus.

The second article relates on the a more general context of what’s bad about ride hailing/ride sharing. The author presents not just a list but evidence of each item mentioned.

As I’ve mentioned in previous articles here, there are still a lot we need to learn about ridehailing in this country and especially in our cities. I guess Angkas’ case can be different because motorcycle taxis were already operating in many areas even before the app-based service. But of course, we also need to understand about his enhanced ‘habal-habal’.
I chanced upon the changing of the shifts for a national high school. This was the time of day when the morning shift students were dismissed (i.e., coming out of school) and the afternoon shift students were coming in.
Students come out of the school to mainly either walk or take public transport (mostly tricycles) to their homes.
Most vehicles give way to people, especially students, crossing the busy street. There are usually traffic aides in the area who help manage traffic and to ensure pedestrians may safely cross or move about.
There are no severe traffic congestion here unlike those generated by many exclusive or private schools. There is actually a private school just beside this public high school that also generates significant private vehicle traffic but somehow manages not to congest this major road that’s part of the L. Sumulong Memorial Circle the way another private school congests Sumulong Highway in the mornings.
Is this simply because of the school being a public school as compared with private schools? Perhaps it is, given the perceived disparity in income classes concerning those going to typical public schools and those going to typical exclusive schools. But income disparity aside, wouldn’t it be possible for most students to just walk or take public transport to school? I actually envy the public school students in the photos above as they can walk to school. And that is because they likely live near the school, which is something that is a desirable situation if public schools are at least at par in quality with the more established private schools (especially the sectarian ones where many parents likely prefer their children to go to). This disparity in quality leads to people residing in relatively long distances away for the preferred schools to travel (often with their private vehicles) to and from the exclusive schools. The point here is that it really is more complicated than what it seems in terms of trip generation.
Much has been written about the traffic along EDSA, which is perhaps Metro Manila’s most famous (some would say infamous) thoroughfare. These include the unpredictability of congestion along this road. While it is hard to believe that traffic congestion is unpredictable for EDSA because very often it is congested, there are times when you just marvel that its free-flowing during the day or shocked that its packed with cars close to midnight. Last week, we experienced both predictability and unpredictability in the sense that we did expect EDSA to be congested near Ortigas (due to the dismissals of schools in the vicinity) but didn’t expect it to be packed during what we thought was “alanganin na oras” that was around 3PM.

Interestingly, there was no congestion after Ortigas Avenue and we quickly made up for the time lost in the congestion we experienced from Gil Puyat Avenue. Is this another case of the phantom congestion where the simple disturbances in the traffic stream can create a ripple effect resulting in congestion? Or is this somewhat like an everyday thing? EDSA is not part of my daily commute so I am not so sure about the regularity of this situation but at least the weather didn’t factor in the equation. Heavy rains usually lead to flash floods along this thoroughfare, and these floods will definitely lead intense congestion.
There’s a recent decision by the Metro Manila Council (MMC) comprised of the mayors of the cities and municipality of Metro Manila and chaired by the Metro Manila Development Authority (MMDA) Chair that vehicles bearing only one passenger (the driver) will be banned from travelling along EDSA. The problem with this is that by banning cars with one passenger from EDSA, you only succeed in making other roads like C5 more congested. It’s a simple case of transferring traffic and worsening it elsewhere since you’re not doing anything to alleviate congestion along those roads. Did MMDA run this and other scenarios using analytical or simulation tools at their disposal? If so, can these be shown and used to explain the soundness of this policy approved by the MMC? I suspect they didn’t and likely depended more on gut feel based on the data they have including what is often reported as 70% of vehicles traveling along EDSA having only one passenger. Meanwhile, the state of mass transit along EDSA still sucks.

Of course, the pronouncement from the MMDA launched quite a lot of memes on social media. Some people shared the typical quotes on planning (you know, like the ones about planning for people vs. planning for cars). Some offered their own ideas about how to “solve” traffic along EDSA. And so on…that only succeeded in showing how everyone had an opinion about transport and traffic. Everyone is an expert, so it seems.
Some thoughts and not in any order:
- The government can initially dedicate a lane each for express buses (a la Bus Rapid Transit or BRT). This idea has been circulating for quite some time now and has a good chance of succeeding. The DOTr is already deploying buses that they say are supplementing the MRT 3 trains (i.e., there aren’t enough trains running so passengers have the option of taking a bus instead). Running along the inner lanes of EDSA would mean, however, that they would have to find a way for passengers to cross the road and one idea would be for the stations to be retrofitted for this purpose.
- Those cars along EDSA are not necessarily for short trips so walking and cycling while needing space may have less impact in the immediate term for such a corridor. In the meantime, serious consideration should be made for bike lanes whether on the ground or elevated and improvements to walking spaces.
- But these efforts to improve passenger (and freight) flows should be a network-wide thing and not just along EDSA.
- It’s time to have serious discussions and perhaps simulations (even a dry run) of congestion pricing in Metro Manila. Congestion pricing for all major roads and not just one or two. Funds collected goes to mass transit, walkways and bikeways development. DOTr was supposed to have already discussed an Electronic Road Pricing (ERP) system like Singapore’s with the company and people behind the same in the city-state. That doesn’t seem to be moving along.
- Working and studying from home might work in terms of reducing vehicular traffic but then we generally have lousy internet services so that’s a barrier that needs to be broken down.
- How about legalizing, once and for all, motorcycle taxis? Many are opposed to this citing safety concerns but then we are running out of options outside the usual motherhood statements pertaining to building transport infrastructure. Think about it. Give it a chance. These motorcycles might just surprise us in a nice way; that is, helping alleviate congestion.
- Carpooling and lanes dedicated to High Occupancy Vehicles (HOV) would be good but the LTFRB made a pronouncement about these being illegal as they would be considered ‘colorum’. Such statements do not make the situation any easier and sends mixed signals as to the government’s being serious in considering all possible angles to improve transport and traffic particularly for commuting.
Do you have other ideas to share?
It’s school time once again in most parts of the Philippines. Public and private schools including most colleges and universities have resumed classes this month of June while others start this July and August. But with the resumption of classes, there is also the re-emergence of issues pertaining to the safety of these children. Students are exposed to the hazards of commuting. These include the likelihood of being injured or killed by vehicles running along the roads the students use to get to school.
The photo above is a typical scene in front and around many public schools in the country. Schools are located along national roads and often lack spaces for students and their guardians. Many end up occupying the roads and causing congestion. Of course, that congestion is secondary to the safety of these children. Nevertheless, such issues need to be addressed in a more holistic manner rather than attempt to solve one as if they could be isolated.
Most students of grade schools and high schools around the country either walk or take public transportation in their commutes. They are exposed almost daily to motor vehicle traffic along the roads and risk being sideswiped or run over by vehicles. In certain cases, small children walk significant distances thereby increasing the likelihood and risk of being harmed by traffic.
Traffic is particularly bad along most roads leading to schools mainly during the morning, mid-day and afternoon periods when students arrive or leave their schools. In Metro Manila, for example, the worst congestion are experienced along major roads like Katipunan Avenue (due to traffic generated by Ateneo, Miriam and UP) and Ortigas Avenue (due to La Salle Greenhills). That means a lot of time and fuel are wasted and more emissions are released into the air that we breathe. However, one can argue that in terms of road safety, this is better since gridlocks mean slow moving vehicles that make it safer for walking or cycling. This is not the same in the provinces or rural areas where there is less congestion and vehicles travel at faster speeds.

While there are initiatives pertaining to revisions in speed limits, such are limited (pun not intended) by how much action can be done in order to enforce these regulations. Add to this the requirement of having the instruments to measure and record speeds in aid of enforcement. This was what MMDA did along Commonwealth Ave. and Macapagal Blvd. with the acquisition of two speed guns. I don’t see them using these anymore and wonder if the instruments are still working. Meanwhile, expressway authorities are using these as they continue their enforcement of speed limits along tollways. [I am aware of NLEX and SCTEX enforcement units employing speed guns along those tollways.]
The DPWH is also doing its part by doing road safety audits and identifying measures to reduce the likelihood of crashes involving these students. Among these are rumbles strips and, in some cases, the construction of sidewalks but these are not enough. There were recommendations from an iRAP project many years ago but the agency was resistant to what they thought were new and innovative ideas that were actually already being implemented in other countries. Perhaps these recommendations and that iRAP study could be revisited and solutions drawn from there?
I recently read an article about the opposition to road diets in California, USA:
Tinoco, M. (2018) “How to Kill a Bike Lane”, http://www.citylab.com, https://www.citylab.com/transportation/2018/05/how-to-kill-a-bike-lane/559934/?utm_source=SFTwitter [Last accessed: 5/20/2018]
So far, we know that at least three cities are progressive enough to implement road diets including Marikina City, Pasig City and Quezon City. Iloilo doesn’t count yet since their bike lane was constructed along the very wide Diversion Road. Our recommendations for Tacloban, if implemented by the city, will probably result in the second most comprehensive application of road diets/complete streets in the Philippines after Marikina, which implemented their bikeways network almost 2 decades ago. There are sure to be many who would be opposed to such schemes as many still have the view that streets are for motor vehicles. This car-oriented thinking is something that will be a challenge to advocates of people-oriented transportation systems. Hopefully, many can learn from experiences here and abroad on how to reclaim space for people leading to safer and more inclusive transport for all.
