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. Serina Mechanical Engineering Professorial Chair) presented on “Reduction of Light Rail Transport Energy Demand via Powertrain Modeling and Optimization of Operating Parameters”; 2) Dr. Juvy A. Balbarona (Renato M. Tanseco Professorial Chair) presented on “Timetable Optimization for Light Rail Transit (LRT 1)”; 3) Asst. Prof. Roderaid T. Ibanez (Team Energy Professorial Chair) presented on “Energy Demand Quantification and Conservation Strategies of Bus Transport Terminal Facilities along EDSA”; and 4) Dr. Edwin N. Quiros (Federico E. Puno Professorial Chair) presented on “Fuel Economy Results from Diesel engine Tuning for Steady Speed and Drive Cycle Operation”.
There is one transport related topic in the Department of Computer Science colloquium. On October 25, Dr. John Justine S. Villar (Dean Reynaldo Vea Professorial Chair) will be presenting on the “Efficiency Measurement of Domestic Ports in the Philippines Using Data Envelopment Analysis.”
The Institute of Civil Engineering will be holding its colloquium on October 28 – 29, 2021 with the following transport-related topics: 1) Asst. Prof. Rosabelle Louise A. Caram (DCCD Engineering Corporation Professorial Chair), “Utilization of Plastic Laminates in Asphalt Cement Mastic”; 2) Dr. Hilario Sean O. Palmiano (David M. Consunji Professorial Chair in Engineering), “Validation of a Customized Local Traffic Simulator (LocalSim)”; 3) Dr. Jose Regin F. Regidor (Ambrosio Magsaysay Professorial Chair in Engineering), “Pedestrian Safety Assessment Within Public Elementary School Zones in Quezon City using Star Rating for Schools”; 4) Dr. Ricardo DG. Sigua (Dr. Olegario G. Villoria, Jr. Professorial Chair in Transportation/Logistics), “Study of Motorcycle Rider Casualties at Signalized and Unsignalized Intersections”; 5) Dr. Karl B.N. Vergel (Quintin and Norma Calderon Professorial Chair), “Estimation of Transportation Energy Demand of the Philippines”.
Other departments have not posted yet about their schedules or topics yet. The Electrical and Electronics Engineering Institute (EEEI), for example, will have their colloquium this coming October 25 but have not posted a detailed schedule yet. They usually have several transport-related topics including those on traffic signals, vehicle detection, and bike share innovations.

Here’s a list of papers from the Philippines presented at the recent 14th International Conference of the Eastern Asia Society for Transportation Studies (EASTS). The local society, the Transportation Science Society of the Philippines (TSSP), is affiliated with EASTS being one of the founding societies for what is now the mother organization with members across Asia.
I thought the list would be helpful to those who come to this site to look for research topics. I guess it’s that time of the year for many university/college students who are looking for topics for their thesis or dissertation. There’s a nice mix of topics in the list and shows what are the current topics students and faculty from the different schools are engaged in. Many appear to be from research projects, which are a natural source for technical papers being submitted, presented and published in conferences or journals.
The TSSP is holding its own virtual conference in November 2021. I will also share about that and the papers to be presented in that conference in a future post. Currently, they have not finalized the program and papers submitted are still being reviewed.
I would have been in Hiroshima, Japan today if it weren’t for the pandemic. I would have been attending this conference from this weekend (September 12 to 14) where my colleagues and I will be presenting our papers at the respective sessions according to the topics of our work. This year, the conference is virtual and we submitted recorded presentations though presence during the sessions is still required to answer questions about the papers presented. A pre conference even was already held yesterday that attracted early career research in transportation. Here is the link to the conference hosted by Hiroshima University.
I have been to Hiroshima once but unfortunately it was a busy trip to the university and I could not go around. I had wanted to go the memorial to the atomic bomb attack on the city. The plan we had before the pandemic was to have a post conference trip to Kyoto and then proceed to Tokyo on what could have been another sentimental journey for me and close friends who have also studied in Japan. Perhaps there will be another opportunity soon and that we can already travel even with the restrictions or health protocols pertaining to Covid-19.
I noticed again that there seem to be a lot of ‘hits’ for articles I wrote years ago about research topics. Many appear to be looking for topics for their university/college/school research projects including those who might be looking for thesis or dissertation topics. Here are some of my past postings on research topics:
August 11, 2017: https://d0ctrine.com/2017/08/11/topics-for-transportation-research/
It is from the July 4, 2015 article where I wrote something that is still very much applicable today or perhaps anytime someone asks about what topics should be pursued by undergraduate, graduate and even faculty research:
“Schools need to develop their own research agendas. That is so that students would be able to choose topics that their faculty can realistically and effectively guide their students instead of sending them out to become the burdens of others. These would include topics concerning local issues. Are there road safety issues at locations such as intersections near the school? Are the streets in the nearby CBD experiencing congestion? Is there an oversupply or lack of public transport services in the city or a nearby town? It seems awkward for a university in Pampanga, for example, to have students taking on a topic concerning EDSA-MRT or students of a university in Metro Manila taking on a topic on Mindanao railways, if their faculty have no relevant experiences or capabilities to properly guide the students.
I would encourage schools to identify topics concerning local issues first. As they say, charity begins at home, and working on solutions for local problems should be top of the agenda of any school. That includes us at UP and there are many topics that focus on issues in and around UP Diliman. If we can’t solve our own problems then how can we be believable in addressing those outside our direct influence area?”
I do encourage prospective student researchers to take on topics addressing local transportation issues. Some recommendations are as follows:
- Active transport – topics on bike use, bike lanes planning and design, pedestrian or cycling facilities, safety, funding and investments, integration with public transport, end of trip facilities, IEC or C4D materials development and deployment, etc.;
- Road/highways – topics on road safety, road capacity (e.g., assessing the necessity and/or effectiveness of road widening projects);
- Public transportation – topics on rationalization, modernization, services in the time of Covid-19, business models including service contracting, motorcycles as public transport (i.e., motorcycle taxis);
- Anything relating transport and the pandemic – topics about transport in the so-called new normal, impacts of Covid-19 on transport, traffic, commuting, etc. These topics can be framed a number of ways and can be very local (i.e., based on local experiences) and/or comparative.
There are obviously more including the “classic” ones on traffic engineering and management (e.g., traffic congestion, intersection analysis, development of micro-simulation models, etc.), transport planning (e.g., travel demand forecasting, transport model development, etc.), as well as those on the various modes of transport (air, maritime and rail come to mind). The objective is to be able to contextualize and address issues closer to your home rather than far from it. I think that’s how best you can contribute to addressing transport problems rather than be over-ambitious or messianic in your research topic(s).
I was in a meeting that started off well enough but was accentuated and concluded on sour notes. It was where 2 governmentt officials basically berated and ridiculed us representing academe. Dinaan lang kunyari sa mapalamuting pananalita nila. Well, no matter how you twist your words, we could still decode their meaning. I guess that goes with years of experience listening to all kinds of talk from government officials, politicians, people in private sector, consultants, faculty members, researchers and yes, students. You know bullshit even if its hiding behind a bunch of flowers.
I think the idea of certain government officials about the role of academe in development is to essentially be rubber stamps of the administration. Those who offer criticisms or disagree with plans, policies or parts of these are often branded as “bad apples”. Bawal kumontra. I guess that comes from people who are basically insecure with their work or outputs? Or perhaps they are just worried about their standing and image considering the very political environment they are working in. I could not use the word ‘validate’ to describe the expectation from academe from the government officials in that meeting since the process of validation may end up either positive or negative (thereby invalidating something such as a plan or a policy).
There will always be newer tools and newer models. I remember the times when JICA STRADA was supposed to be the state-of-the-art travel demand forecasting software. It was easily overtaken by the like of CUBE and Vissum. Even its simulator was not at par with VISSIM, Dynasim and a host of other micro-simulation software packages that were more user friendly. Better tools allow for better models, but also only if you do your part in collecting the data required for calibration and validation and formulate sound assumptions. As they say, garbage in, garbage out. No matter how sophisticated your computer models seem to be, they are nothing if your assumptions and data are rubbish. As Howard Stark states in his recorded message to Tony, “I am limited by the technology of my time. But one day, you’ll figure this out.” And not only will there be newer tools and models, there will also be newer methods including those that allow for more sophisticated data collection.
Plan formulation and acceptance are not as simple as 1+1 as one official used as an example. It’s actually more complicated than that. Plans don’t and should not be described in absolutes but should be dynamic or evolving since the future is also uncertain and there are so many factors in play that cannot be all represented or modeled. And no, we’re not going to toe the line nor will we tell other academics to do so. In fact we will continue to be outspoken because that is part of how it is to be objective, and to be encouraging of critical thinking. It is the latter that needs to be instilled in many government agencies where people tend to forget about it likely for convenience as well as to conform with the political atmosphere.
The presence of respected Japanese professors in the meeting and their likely role in convincing JICA to convene an experts’ panel meeting. The meeting was with certain academics representing schools that were not initially engaged by government. JICA’s nod is recognition enough of the accomplishments and reputation of those of us who were invited to the meeting. Unfortunately, their expertise are not appreciated by their own government but that seems to be the consistent policy for the current administration that rewards those who toe the line while shunning those who are more objective and critical.
Culturally though, I am not surprised of the proceedings because we don’t have the same reverence for academe as they have in Japan or other countries where academics are regularly called upon to provide insights to address problems such as those pertaining to transportation. That is why they have strong advisory councils in those countries. And in the case of the US, for example, their National Academies have contributed much to transport development. I have experienced something similar from a top government official before regarding traffic management and policies in Metro Manila. Whether that set-up in the US and Japan can be realized here remains to be seen.
It’s that time of year again when I usually write about research topics. I am tempted to share the updated research agenda our group prepared for our students at UP but perhaps a quick list would do for now. I guess the most relevant topics are those related to the Covid-19 pandemic including those about transport during the lockdown and post-ECQ. Here are some initial ideas about such relevant topics to take on:
- Public transport supply and demand, operations – there are many topics that can be developed under this including those relating supply and demand. For example, it would be interesting to have a research assessing the supply of public transport modes with respect to the demand from the lockdown (ECQ to MECQ) to its easing (GCQ to MGCQ). Included here would be topics tackling the attempts at rationalizing transport routes (e.g., the introduction of bus services where there was none before, the continuing restriction for conventional/traditional jeepneys, etc.). For those into transport economics and finance and even policy, perhaps the service contracting scheme can be studied further and its different aspects meticulously and objectively examined. What are its limitations? What are the critical assumptions that need to be realized for it to be most effective and not abused or mismanaged?
- Traffic engineering and management – there were suddenly many issues pertaining to this during the lockdowns. Among these were traffic management in the vicinity of checkpoints where queuing theory among other principles could have been applied in order to reduce congestion.
- Active transportation – the DPWH already came out with guidelines for bike lanes along national roads. These will surely be used as reference by local government units (LGU) as they are obliged by a DILG memo to develop facilities for active transportation. Active transport here refers mainly to walking and cycling but in other cases have come to include the use of personal mobility devices (PMD). Much research is to be done for designs, users’ preferences, behavior in traffic, safety and other topics such as those relating active transport with public transport (e.g., as a last mile/kilometer mode for most people).
- Level of service (LOS) – I had a nice, brief exchange about LOS and the notion that it is outdated. I believe it is not and many who parrot the notion lacks a deeper understanding not just of LOS but the principles, assumptions and data that goes into transportation and traffic analysis. Perhaps a multi-modal LOS criteria can be developed for the Philippines? If so, what parameters or measures can be used to describe our own LOS? What modes and facilities will be evaluated according to this? And how can solutions be developed with respect to such.
Of course, there are just so many of the traditional topics to take on. There will always be a backlog regarding these topics. In the sequel to this article, I will try to identify other topics for transportation research that can be considered as well as recall “old” topics that are still necessary regardless of the pandemic.
Here’s a nice link to a National Academies of Science, Engineering and Medicine pointing to the wealth of researches supporting improvements for active transportation:
The references listed should aid researchers, practitioners, advocates and policymakers in their work towards realizing a people-oriented vs car-centric transportation.
There is a perception that cyclists tend to slow down other vehicles, mainly motorized, along roads. Again, such can be the experience of some that have been generalized and accepted as fact in most cases. However, if we look closely at the evidence, the perception may not be true for most cases after all. This article comes out of Portland State University:
Schaefer, J., Figliozzi, M. and Unnikrishnan, A. (2020) “Do bicycles slow down cars on low speed, low traffic roads? Latest research says ‘no’,” EurekAlert!, https://eurekalert.org/pub_releases/2020-07/psu-dbs072320.php [Last accessed: 8/1/2020]
Check out the wealth of information through the links found throughout the article that includes references to published material in reputable journals. EurekAlert! is from the American Association for the Advancement of Science (AAAS).
Here is a nice article from the National Academies of Science, Engineering and Medicine about how transportation research makes roads safer for students as they go back to school:
There is a wealth of information there, and one should browse and perhaps download resources shared that can be useful references not just for those in North America but elsewhere towards making journeys between homes and schools.

We, too, have several initiatives towards making the journeys of children safer between their homes and schools. It is something that all of us find essential and worthwhile. Children, after all, represent our future and making their journeys safer gives them better chances to succeed in life. It also shows them examples that they can replicate for their own future children. I will write more about these as we obtain the data and perform our assessment.
There are many references that are free for downloading. These include the latest publications from the National Academies Press that includes outputs from the National Academies of Sciences, Engineering and Medicine. I am sharing here and posting also as a reference for me to return to a new publication from the National Cooperative Highway Research Program:
NCHRP Research Report 941: Bicyclist Facility Preferences and Effects on Increasing Bicycle Trips by Watkins, Clark, Mokhtarian, Circella, Handy and Kendall.
The research was supported by the American Association of State Highway and Transportation Officials (AASHTO) in cooperation with the Federal Highway Administration (FHWA).
