On walkability and walkability scores

I’m sharing a couple of articles on walkability and walkability scores. The first one actually points to the second but provides brief insights about the concept of walkability while the second is a more detailed article on the findings of a study on walkability.

Ionesco, D. (May 4, 2022) “Walkability Scores Don’t Tell the Whole Story,” Planetizen, https://www.planetizen.com/news/2022/05/117075-walkability-scores-dont-tell-whole-story?utm_source=newswire&utm_medium=email&utm_campaign=news-05052022&mc_cid=c04e3e4dc0&mc_eid=9ccfe464b1 [Last accessed: 5/7/2022]

To quote from the article:

“if cities truly want to be pedestrian-friendly, they need to think beyond the sidewalk…”

The second article is from late April:

Gwam, P., Noble, E. and Freemark, Y. (April 28, 2022) “Redefining Walkability,” urban.org, https://www.urban.org/features/redefining-walkability [Last accessed: 5/7/2022]

To quote from the article:

“To create a more comfortable walking experience, our research points to a few steps DC planners and policymakers can take to increase racially equitable walkability across the city:

  • expand tree cover in the densest parts of the city,

  • increase nonautomotive modes of transportation in central areas,

  • reduce noise pollution,

  • support more equitable access to key resources, and

  • prioritize road design that limits the need for police traffic enforcement.”

While the article puts emphasis on the topic of racial equity, such concept can easily be adapted and adopted for our purposes. For one, it could be interpreted as being inclusive if one is not comfortable with the term “race”.

Don’t miss downloading the technical appendix of their report. This will be very useful to researchers, practitioners and advocates of active transport.

Trivia: Why are school buses yellow?

Have you every wondered why are school buses yellow? Of course, the main reason is safety related. Here is a short article on why the color was chosen for school buses:

Ganninger, D. (August 20, 2020) “Why are school buses yellow?” Medium.com, https://medium.com/knowledge-stew/why-are-school-buses-yellow-2f2b063739d4 [Last accessed: 3/20/2022]

To quote from the article:

“The original color was called National School Bus Chrome but has since changed since school bus chrome contained lead in the pigment. The color was adopted because black lettering was easy to see in the early morning hours and during the late afternoon. Another reason it was chosen was because the color yellow is seen quickly in someone’s peripheral vision.”

Articles on air crash incidents

I posted earlier this month about references online on railway crash incidents. This time, I am sharing a site where you can find articles about air crash incidents. There are many interesting articles here including some of the most well-known incidents that involved pilot error, weather-related crashes and those involving aircraft defects or issues.  There are also articles here about terror attacks that led to air crashes.

I have shared a few of his articles before including one on the Concorde crash and another about the ill-fated Malaysian Airlines Flight 370. I have found these articles to be very interesting as the manner of writing is investigative and evidence-based. I have myself been in several near incidents, which I have related in this blog.

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.”

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: http://ncts.upd.edu.ph/tssp/

We need to do more to reduce transport emissions

I did some work on long term action plans on low carbon transport for the ASEAN region before. We were able identify many of interventions that were being implemented as well as those that can be done to reduce transport emissions. Such reductions for the region would ultimately contribute to alleviating global warming. Unfortunately, while ASEAN is a significant contributor to emissions, it pales in comparison to emissions by individual countries like China and the US. If these two and others in the industrialized world do not commit to reducing their emissions, all work will come to naught. Here is an article that serves as a pre-event write-up for COP26, a major climate summit that will be held in Glasgow in the coming days.

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. 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.

More details and updates including registration to these colloquia may be found at the UP College of Engineering Facebook page: https://www.facebook.com/updengg

Papers from the Philippines presented in the EASTS 2021 conference

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.

EASTS 2021 Conference

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.

Undergraduate and graduate research topics, 2021

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:

October 12, 2011: https://d0ctrine.com/2011/10/12/undergraduate-research-topics-on-transportation-2011-2012/

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).
