How my students see transport and traffic

With social media and the ascendance or popularity of influencers and the like, we have often encountered assessments or opinions about transportation and traffic. While there are those that make sense, there are more that are of the rant variety. The latter include the self-righteous who seem to relish bashing professionals and government officials while not being able to present much in terms of their own accomplishments. I am aware of my students (including research advisees) being aware of these people and I often see them posting their comments on topics, articles and opinions being shared on social media. For most, their comments and posts on social media show they’re being more informed than most, especially about the state of transportation in the country.

Here are some observations and comments from my students:

  1. One of my students asked me about my take on the public transport situation. I replied that it is unfortunate that public transportation has deteriorated the way it has for the past decades. The current state is not due to recent policies or regulations but a product of various policies, regulations and even trends over so many years. My student countered that perhaps the current officials must not make an excuse of the past in failing to act in the present.
  2. I always read about posts that anchor their arguments on the supposed low car ownership in Metro Manila. These are usually followed by calls for taking lanes away from car use for public transport and cycling. While I agree with the latter, I don’t with the former arguments. A student was curious about my statement in one lecture that we need to validate the numbers because what we see on the streets appears to be inconsistent with the notion of low car ownership. There are other ways, she said, to determine vehicle ownership other than the conventional HIS data. We could probably use the Family Income and Expenditure Survey (FIES) that is regularly conducted by the Philippines Statistics Authority (PSA). This will show if people own motor vehicles as well as how much they spend for transportation.
  3. I asked my students to critique the plans and implementation of airports in the Greater Capital Region (GCR) also known as Mega Manila, and which is larger than the NCR Plus used to refer to Metro Manila plus Bulacan, Rizal, Laguna and Cavite. I was not surprised about their assessments as all of them did their homework in the sense that they researched on information and data they could use for their critiques. Most were in favor of developing a new capital airport in Bulacan rather than in Cavite. And many favored the continued operation of NAIA but with reduced air traffic and a different role.

More on these opinions, observations and comments as I try to recall the more remarkable or notable ones.

Have a nice Sunday!

On university-community collaborations

I’m not a stranger to university-community collaborations. In fact, I even helped draft a proposal for the World Bank to support such collaborations, which I believe would be sustainable and therefore worthwhile to be pursued by potential partner universities and local government units. There are actually many such collaborations but most of these are probably informal with certain faculty members of universities (usually state universities or colleges) being involved in committees or moonlighting in projects implemented or funded by LGUs. I say informal because technically, the school is not involved in the project and it is only incidental that the person or persons involved are affiliated with the university or college.

Here is an article showing an example of university-community collaborations:

National Institute for Transportation and Communities (2022) “Transportation recovery after disasters: A collaborative university/community model,”, [Last accessed: 8/15/2022]

The authors wrote about actions that could be done “to build future economic resilience.” To quote from the article:

  • Increasing pre-disaster investment in resilient transportation infrastructure to reduce the cost of eventual recovery;

  • Improving business resilience practices for high-impact industrial sectors, through education and outreach;

  • Identifying structural barriers to adoption of resilient business practices, and promoting mitigation through recovery.

  • Mainstreaming disaster resilience into economic development by breaking the siloed approach to emergency management and economic development.

While these actions were framed for the community engaged by the University of Utah, they are general enough to be applicable to other communities as well.

I mentioned earlier about the need for formality. The Commission on Higher Education (CHED) encourages and supports what are termed as Extension Works or Extension Projects by higher education institutions. These may be in various forms including committee work, advisory, capacity building/training, or even professional work/services provided to the province, city or municipality (even barangay). But there should be accountability here as well as the proper assignment or allocation of resources.

Just compensation is one of the more sensitive or tricky elements or items here as often, LGUs would like to get something for free or assume that certain services are free. They are not and time and effort should be compensated; just not the international rates you might expect for consulting work from the likes of World Bank or Asian Development Bank.

Here is where contracts (e.g., in the form of Memorandum of Understanding (MOU) or Memorandum of Agreement (MOA)) can be useful to establish the terms of engagement that includes budgets for Personnel Services (PS), Equipment Outlay (EO) and Maintenance and Other Operating Expenses (MOOE). The latter categories should be familiar with LGUs because these are standard items under which details are provided for their programs and projects. State universities and colleges are also familiar with these as standard government terminologies for budgets. Of course, that goes without saying that in certain engagements, there may be third parties such as donor or funding institutions that will should all, most, or part of the costs for collaborative work.

Opinions on the current transportation situation?

Some people were asking me about what I thought about certain issues and reports on transportation. To be honest, while I am involved in some projects including one on road safety, I have been busy (or swamped is probably a more suitable term) with administrative duties at the university. While I take a peek from time to time, as is my habit, to see what’s happening, I have much less time to really engage or get involved in discussions. Whereas before, I easily get myself into typing comments and engaging in some discussions about transport issues particularly in social media, I now quite easily turn away and let it be. There are, after all, a lot of people experts, pundits, advocates, even trolls who are “slugging it out” with their opinions on just about anything on transport.

While I am amused at many discussions or posts, I now find myself not at all wanting to get involved unlike before. I think perhaps I have done my part and continue to do so in ways and avenues where I am more effective and where my time and effort is not wasted and more appreciated. I have never been the loud person in a room and have always tried to have my work speak for myself.

The indifference is the product of many factors and circumstances including becoming tired of doing interviews with conventional media. Nowadays especially, when media seems engrossed on having content by the minute; never mind the substance. Basta may ma-report or ma-post (As long as their is something to report or post).

Well, here’s a few thoughts about what seem to be trending these days:

  1. There is still a lack of public transportation supply considering the increasing demand (more people are back to their workplaces and schools are already reopening!). Government agencies still seem to be clueless or perhaps just want to push the original rationalization and modernization programs despite the pandemic changing the game for commuting demand. Due to the lack of public transport, more people are taking to private vehicles but certain observers apparently see only cars (which they automatically equate to ‘private vehicles’). Motorcycles are also increasing in numbers and allowing motorcycle taxis will mean people will turn to these for commuting/transport needs.
  2. Cable cars won’t solve Metro Manila transport or traffic woes. Even if one will consider where they will fit or may be suitable, this is still a band aid solution considering all the solutions including the ones that are obvious or staring us in our faces (yes, allow the conventional jeepneys and buses back for now) that are available but government stubbornly rejects. As for the senator who broached the idea, I think he did so mainly for media mileage (and the mainstream media quickly snapped it up!) – para mapag-usapan. As they say – it’s so showbiz!
  3. I still believe that the experiences from the pandemic strongly provide us with the evidence to support a continuation and sustaining work-from-home or remote work set-ups. This actually ‘solved’ traffic during the heights of the pandemic and yet we choose to revert to the old normal set-up. People are languishing, suffering as they spend long travel times in their commutes. These are unproductive time that people could have spent more efficiently and productively (not to mention more meaningful) at home.
  4. I support children going back to school but not for 100% of their times. We definitely know that a 100% study-at-home set-up is not for everyone and the last two years have affected our children including their need for face-to-face interaction with other children (classmates) and adults (teachers). Still, we can have a blended set-up where perhaps we can have children come to school 2 to 3 days in a week rather than the old normal of 5 to 6 (even 7 in some schools) days. Other tasks and learning activities can be done effectively at home. This also could help ease traffic and travel demand especially in urbanized areas.

On phasing out cars in cities

I’m sharing another article on reducing car dependence. The article was referred to by the previous series that I shared recently.

Nicholas, K. (April 14, 2022) “12 best ways to get cars out of cities – ranked by new research,” The Conversation, [Last accessed: 5/20/2022]

Here are a few excerpts from the article:

“Question: what do the following statistics have in common?

The second-largest (and growing) source of climate pollution in Europe.
The leading killer of children in both the US and Europe.
A principal cause of stress-inducing noise pollution and life-shortening air pollution in European cities.
A leading driver of the widening gap between rich and poor urban residents.

Answer: the vehicles on our streets, primarily the not-so-humble passenger car.”

also this:

“The research is clear: to improve health outcomes, meet climate targets and create more liveable cities, reducing car use should be an urgent priority.”

and this:

“To meet the planet’s health and climate goals, city governments need to make the necessary transitions for sustainable mobility by, first, avoiding the need for mobility (see Paris’s 15-minute city); second, shifting remaining mobility needs from cars to active and public transport wherever possible; and finally, improving the cars that remain to be zero-emission.”

Articles on examining the role of the planning profession in both perpetuating and solving traffic congestion

Planetizen recently published a three-part series of articles examining the role of the planning profession in both perpetuating and solving traffic congestion:

Part 1: Brasuell, J. (April 13, 2022) “Planning and the Complicated Causes and Effects of Congestion,” Planetizen, [Last accessed: 5/17/2022]

Part 2: Brasuell, J. (April 20, 2022) “How Planning Fails to Solve Congestion,” Planetizen, accessed: 5/17/2022]

Part 3: Brasuell, J. (May 12, 2022) “Planning for Congestion Relief,” Planetizen, [Last accessed: 5/17/2022]

I think these articles are a must read especially for students (and not just practitioners or professionals) and is sort of a crash course on transportation engineering and planning. It covers many concepts and learnings from so many decades and touches on certain programs that are most effective in reducing car trips. To quote from the article, the top 12 programs based on case studies in Europe are:

  1. Congestion Pricing (12-33% reduction in city-center cars)
  2. Parking and Traffic Controls (11-19% reduction in city-center cars)
  3. Limited Traffic Zones (10-20% reduction in city-center cars)
  4. Workplace Mobility Services (37% drop in car commuters)
  5. Workplace Parking Charges (8-25% reduction in car commuters)
  6. Workplace Travel Planning (3-18% drop in car use by commuters)
  7. University Travel Planning (7-27% reduction in car use by university commuters)
  8. University Mobility Services (24% drop in students commuting by car)
  9. Car Sharing (12-15 private cars replaced by each shared car)
  10. School Travel Planning (5-11% reduction in car use for school trips)
  11. Personalized Travel Planning (6-12% drop in car use share among residents)
  12. App-Based Incentives (73% – proportion of app users declaring reduced car use)

Are we ready to confront congestion and at the least start discussing these car trip reduction programs? Or are we content with the current discourse, which remains car-centric?

Some old drawing tools for clothoids

I took some photos of old (vintage if you prefer) drawing tools that I have at our laboratory at the university. We found this in the storage many years ago and people seem to have forgotten about them. Instead of heading for storage or being forgotten or worse, thrown away, we decided to keep them at our laboratory mainly to show our students how certain highway or street curves were drawn in the ‘old days’. I am currently the custodian of this and another set that I have kept at my other office at the civil engineering building.

The wooden box is at my office at UP Diliman

The sign basically translates to clothoid drawing tools made by a company based in Setagaya in Tokyo. There are 14 instruments in the box for clothoid parameter values of A = 20m to 350m.

Opening the box shows slots holding instruments for drawing clothoids or spiral curves

Some of the instruments from the case – the large one on top is for A = 300m and 350m (scale 1:1000)

Comparison of size of instruments for (top) A = 60m and 65m, and (bottom) A = 30m and 35m (scale 1:1000)

Instrument for A = 30m and 35m (Scale 1:1000)

A protractor came along with the set but I assume other instruments such as a compass were used in drawing/drafting the curves.

I shall take photos of the other set when I get to visit the other office. These will be for records purposes as well as for posterity. These are practically museum pieces that are now perhaps rarely if even used.

Paper: Estimation of Transportation Energy Demand of the Philippines Using A Bottom-up Approach

Our paper from a conference last year is finally published in an open access journal. The paper is on the “Estimation of Transportation Energy Demand of the Philippines Using A Bottom-up Approach.” Here is the abstract of the paper:

“In the years 2000–2016, the sector with the largest share of total final energy consumption in the Philippines is transportation with an average share of 34.2%. The study aims to estimate the baseline transportation energy demand of road, maritime, air and rail transportation modes in 2016 using a bottom-up approach. Through a bottom-up approach and utilizing available transportation activity and fuel economy/energy efficiency data from secondary sources coupled with primary road transportation activity and fuel economy and railway operations survey data, the baseline transportation energy demand of the Philippines is estimated to be 12,956.1 ktoe in 2016. A comprehensive estimation of transportation energy demand of the country using bottom-up methodologies with more detailed transportation activity and vehicle fleet of the different transportation modes is implemented. Finally, the collection and keeping of certain data that are critical in the estimation of the transportation energy demand are recommended.”

Here is the link to the paper, which is published in the Asian Transport Studies, Vol. 8, 2022:

Cities and Automobile Dependence: What Have We Learned?

We end the year with an article from Todd Litman via Planetizen. The topic is something that we really need to ponder on as we or if we are to move towards more sustainable transportation for our cities and municipalities. The experiences during this Covid-19 pandemic should have provided us glimpses of how it could be if we put active and public transport above automobile dependence or car-centricity.

TSSP 2021 [27th Annual Conference]

The Transportation Science Society of the Philippines (TSSP) held its 27th Annual Conference last November 19, 2021. Here are the poster and program for the conference:

Poster promoting the conference
The morning part of the conference mainly featured a roundtable discussion.
The afternoon part of the program included 4 technical sessions arranged into 2 parallel sessions.

I initially intended to write about the conference before it was held but things got pretty busy last week so this is a post conference write-up. The organizers also announced the final program late (i.e., just a few days before the conference proper) so it seemed sort of anti climactic to post about it. Nevertheless, the conference proceeded as planned and the TSSP has announced it will be posting the proceedings on their official website. It is not yet there but here’s a link to the TSSP official website:

Transportation topics at the College of Engineering’s Professorial Chair Colloquiums

The College of Engineering of the University of the Philippines Diliman started holding its annual colloquiums (plural because each Institute and Department under the College are holding their colloquium mostly during this last quarter of the year).

The Department of Mechanical Engineering already held theirs last September. There were four topics on transportation: 1) Dr. Gerald Ko C. Denoga (Fernando N.
