More parks and trees = longer lives

Here is an article about a topic that seems unrelated to transportation but is actually strongly related to it. We already know about the benefits of tree-lined boulevards and parks as lungs of a town or city. The following article discusses the benefits and advantages of having more parks and trees.

Yanez, E. (November 19, 2020) “More Parks, Longer Lives,” Parks and Recreation,

I suddenly recall what were tree-lined national highways across the country. Many of these trees were cut down to give way to road-widening projects of the national government through the Department of Public Works and Highways (DPWH)., Nevermind that the widening was not really required in many if not most cases, and that the trees were never replaced or was there ever an effort to do so. The results have been disastrous in terms of the environments along these roads. Transport systems can also be developed with parks and trees in mind; especially if active transport were the focus of the development. Surely parks and trees will enhance the environment and encourage more people to walk or cycle. This should translate into better overall health and wellness for people.

On pollution due to ride shares

We close February with another article I share about ride sharing and its environmental impacts:

Hawking, A.J. (2020) Uber and Lyft generate 70 percent more pollution than trips they displace: study, The Verge, [Last accessed 2/29/2020]

I guess, this sort of validates our suspicion of ridesharing becoming unsustainable. Again, we note its origins when it had the potential to reduce car ownership and car use. The original ride shares were closer to carpooling as well as took advantage of under-utilized vehicles while giving extra income to people who could share their vehicles on-demand. Eventually, the ride shares morphed into taxis with people purchasing cars to get into the business. Soon, a lot of them were roaming the streets as they awaited bookings and this type of operations generated a lot of emissions. They might not have required more parking spaces like the conventional car users but this benefit was eventually overcome by the pollution they produced.

Is there really a transport or traffic crisis in Metro Manila?

I was interviewed recently for a research project by students enrolled in a journalism class. I was asked by one in the group if we indeed have a transport crisis in Metro Manila. The other quickly added “hindi transport, traffic” (not transport but traffic). And so I replied that both terms are valid but refer to different aspects of the daily travel we call “commuting”. “Traffic” generally refers to the flow of vehicles (and people if we are to be inclusive) while “transport” refers to the modes of travel available to us.

“Commuting” is actually not limited to those taking public transportation. The term refers to all regular travel between two locations. The most common pairs are home – office and home – school. The person traveling may use one or a combination of transport modes for the commute. Walking counts including when it is the only mode used. So if your residence is a building just across from your office then your commute probably would be that short walk crossing the street. In the Philippines, however, like “coke” and “Xerox”, which are brands by the way, we have come to associate “commute” with those taking public transportation.

And so we go back to the question or questions- Do we have a transport and traffic crises? My response was we do have a crisis on both aspects of travel. All indicators state so and it is a wonder many including top government transport officials deny this. Consider the following realities for most commuters at present:

  1. Longer travel times – what used to be 30-60 minutes one-way commutes have become 60 – 120 (even 180) minute one-way commutes. Many if not most people now have double, even triple, their previous travel times.
  2. It is more difficult to get a public transport ride – people wait longer to get their rides whether they are in lines at terminals or along the roadside. The latter is worse as you need to compete with others like you wanting to get a ride ahead of others.
  3. People have to wake up and get out of their homes earlier – it used to be that you can wake up at 6:00AM and be able to get a ride or drive to the workplace or school at 7:00/7:30 AM and get there by 8:00 or 9:00AM. Nowadays, you see a lot of people on the road at 5:30AM (even 4:30AM based on what I’ve seen). That means they are waking up earlier than 6:00 AM and its probably worse for school children who either will be fetched by a service vehicle (e.g., school van or bus) or taken by their parents to their schools before going to the workplaces themselves.
  4. People get home later at night – just when you think the mornings are bad, afternoons, evening and nighttimes might even be worse. Again, it’s hard to get a ride and when you drive, traffic congestion might be at its worst especially since most people leave at about the same time after 5:00PM. Coding people and others not wanting to spend time on the road (instead working overtime – with or without additional pay) leave for their homes later and arrive even later.
  5. Less trips for public transport vehicles – traffic congestion leads to this. What used to be 6 roundtrips may now be 4. That affect the bottomline of income for road public transport providers. Given the increased demand and reduced rolling stocks of existing rail lines that includes rail transport.

Smoggy Metro Manila and a look forward to improving transport and air quality in 2019

I took the photo as we were driving up to Antipolo one morning this month when the opportunity presented itself for a quick photo of Metro Manila:

This serves as a reminder for those working to improving air quality in Metro Manila and elsewhere. It has already been established that much of the air pollution in Metro Manila and its adjacent areas can be attributed to mobile sources (i.e., motorised transport). A reduction of motor vehicle use, particularly cars, combined with more efficient engines and cleaner fuels should be lead to significant air quality improvements and, ultimately, an improvement in the quality of life. Of course, there should be parallel efforts to improve facilities for walking and cycling, and implementing the mass transit projects that will carry most people between the origins and destinations regardless of the distances.

Here’s to the approaching 2019 and the optimism that comes with the New Year!

On the need to increase NMT and public transport use

A recent report reinforces what many of us already probably know or are aware of – that we need to shift away from dependence on car use to more sustainable modes of transport in the form of non-motorised transport (NMT) and public transportation. Here is the article from the AASHTO Journal:

Global Climate Report Calls For Expansion Of ‘Non-Motorized’ Transport And Public Transit (2018)

There is a link to the report in the journal article. The report is conveniently available in PDF form and is very readable (i.e., not overly technical).

Incidentally, I was involved some time ago in a project led by the group Clean Air Asia (CAA), which involved several experts from across ASEAN as well as Japan that attempted to determine the necessary transport programs and projects in the region to stave off the projected increase in global temperatures. In all the scenarios evaluated, non-motorised transport (NMT) and a rationalised public transportation system By the term ‘rationalised’ I am referring to the use of higher capacity vehicles as against the taxis and tricycles that typically carry few if not one passenger. Here is a link to the final symposium for that study that has links to the materials presented:

The Final Symposium on the “Study on Long Term Transport Action Plan for ASEAN”

Here’s a slightly updated slide on the future image for a large city in the Philippines:

Incomplete rationalisation of public transport?

The current initiative to rationalise road public transport services is not as comprehensive as necessary or as some people want us to believe. The drive appears to be mainly on (some say against) jeepneys while little has been done on buses and UV Express vehicles. Most notable among the modes not covered by rationalisation are the tricycles.

What really should be the role and place of tricycles in the scheme of themes in public transportation? Are they supposed to provide “last mile” services along with walking and pedicabs (non-motorised 3-wheelers)? Or are they supposed to be another mode competing with jeepneys, buses and vans over distances longer than what they are supposed to be covering? It seems that the convenient excuse for not dealing with them is that tricycles are supposed to be under local governments. That should not be the case and I believe national agencies such as the DOTr and LTFRB should assert their authority but (of course) in close cooperation with LGUs to include tricycles in the rationalisation activities. Only then can we have a more complete rationalisation of transport services for the benefit of everyone.

TSSP 2017 Conference

The Transportation Science Society of the Philippines (TSSP) holds its 24th Annual Conference tomorrow, July 21, 2017. It will be held at the National Center for Transportation Studies at the University of the Philippines Diliman, Quezon City. More than a hundred participants are expected to attend this 1-day affair.

The final program for the conference may be found in the following link:

The theme for this year’s conference is “Improving Quality of Life in Urban and Rural Areas Through Inclusive Transportation.” This is also the theme for the panel discussion in the morning. The afternoon will feature four parallel technical sessions where 18 papers will be presented.

The keynote lecture will be delivered at the start of the conference by Prof. Tetsuo Yai of the Tokyo Institute of Technology, who is also the current President of the Eastern Asia Society for Transportation Studies (EASTS) under whose umbrella the TSSP is part of. TSSP is a founding member of EASTS and actually preceded EASTS by a year.

First call for papers for the TSSP 2017 conference

The first call for papers for the 24th Annual Conference of the Transportation Science Society of the Philippines came out last Wednesday, Feb. 15:


10 principles for sustainable urban transport

We start October with a graphic on sustainable transport. I first saw this shared on social media (FB) by the Clean Air Asia. The organizations behind it are on the graphic itself so I don’t have to list them down for the reader. This is a good material to share and learn from especially for those who don’t have a clear idea of what sustainable transport is and is all about. As they say, pictures paint a thousand words. And illustrations such as this convey so much about sustainable transport in the urban setting in layman’s terms.


Research topics for transportation engineering and planning for 2016-2017?

I observed from my site’s statistics that there have been a lot of interest on research topics in transportation engineering and planning. I regularly post on the undergraduate research topics our students have engaged in. At this point in the first semester of the current 2016-2017 academic year, topics have not yet been assigned and we have only learned how many students have been assigned to our research group. As such, we are still in the process of determining who takes on which topic. Following are topics we have identified in addition to those that had no takers the previous semesters:

Traffic engineering

  1. Anatomy of congestion along EDSA
  2. Anatomy of congestion along C-5
  3. Segregated lane for motorcycles
  4. Impacts of the MMDA’s truck lane policy along C-5
  5. Congestion study in the vicinity of UP Town Center
  6. Assessment of through traffic for the UP Diliman campus

Public transportation

  1. Connectivity study for UP AGT and MRT 7
  2. Feasibility of bus services beyond Masinag junction
  3. Characterization of Internal Public Transportation Operation in UP Diliman and Viability of Introduction of Electric Vehicles
  4. Modelling the Public Transport System of UP Diliman Campus Using CUBE Travel Demand Software
  5. Estimation of Passenger Demand for New Transit System for UP Diliman Using Discrete Choice Model
  6. Characteristics of motorcycle taxis in the Philippines [Habal-habal, skylab, etc.]

Road safety

  1. Severity of injuries of motorcycle riders (helmet and non-helmet users)

Pedestrian & non-motorised transport

  1. A study on walkability along Ortigas Avenue
  2. A study on the characteristics of bike share users in the UP Diliman campus

Transport & Environment

  1. Assessment of Roadside Air Quality along C.P. Garcia Avenue in the Vicinity of UP-ICE Compound

Other topics

  1. Study on the mobility of PWDs in Metro Manila
  2. Assessment of ridesharing in the context of sustainable transport

I’m sure there are other topics but I’m not aware of the specifics at present. Also, we welcome the ideas of our students should they already have topics in mind as long as these preferably fall under the research agenda of our Institute. The topics listed above may appear to be specific but these are still basically very general and can be refined after the students establish their scope and limitations. They can only do that once they have undertaken a decent enough literature review for them also to have a more firm appreciation of their chosen topics. I will post again on this later this year when students would have already put in substantial work on their research proposals (i.e., the objective for this semester).
