How can e-scooters become a safer way to travel?

I’ve shared some articles and opinions about electric scooters. Here is another one that delves into the safety about these vehicles that have become quite popular in the US. Here in the Philippines, they still seem to be in infancy in terms of popularity and to some, are seen as more a novelty and touristy rather than a mode of transport for the typical work trips.

Donahue, B (June 11, 2022) “How to Make Electric Scooters Become a Safer Way to Travel,” Bloomberg, [Last accessed: 6/18/2022]

To quote from the article:

“Dediu believes that in time micromobility will attain critical mass, as other modes of transit have already done, and that infrastructure will come as the user base grows. “We didn’t build airports and then have airplanes show up,” he’s said. “I’m confident, given the history, that we’ll see things like more safe roadways for micromobility vehicles.” “

It is not really about the vehicle but the environment in which it is being used. One can say a lot about walking, for example, being dangerous but without touching on the why and the how its become a dangerous or risky mode of travel. It’s the lack of infrastructure or facilities as well as the car-oriented environment (that includes archaic laws and other regulations) that make active mobility and micro mobility modes dangerous or risky. If we can address these basic issues, then perhaps we can entice more people to use these modes more often and for the most trips we make everyday.

And don’t forget that these modes are the most fuel efficient! Saves you from the every increasing prices of fuel!

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.”

Article on evaluating transport equity

Here is another quick share of an article on transportation equity:

Litman, T. (February 2, 2022) “Evaluating Transportation Equity: ITE Quickbite,” Planetizen, [Last accessed: 2/4/2022]

Transportation equity is a very relevant, very timely topic as people in the Philippines are just beginning to understand and weigh the advantages of having more efficient transport in the forms of active and public transport over private vehicles.

2014 Professorial Chair lectures on transport topics

The 2014 Professorial Chair Colloquium of UP Diliman’s College of Engineering was held from yesterday until today. Most of the lectures concerning transport were presented today. Here are some of the highlights of the lectures delivered this morning:

     IMG09188-20140829-0908Dr. Ric Sigua, Director of the Institute of Civil Engineering, making a point about the economics of Bus Rapid Transit (BRT).

IMG09189-20140829-0949Dr. Sean Palmiano, Director of the National Center for Transportation Studies, explaining the finer points of traffic impact assessment for high density residential developments.

IMG09190-20140829-1019Prof. Happy Denoga of the Department of Mechanical Engineering explaining on the advantages of hybrid systems for vehicles.

IMG09191-20140829-1038Dr. Karl Vergel of the Institute of Civil Engineering talking about the on-road tests for jeepneys using B5 or 5% CME-blended fuels in a project commissioned by the Philippine Coconut Authority.

IMG09193-20140829-1049Dr. Edwin Quiros of the Department of Mechanical Engineering’s Vehicle Research and Testing Laboratory (VRTL)  discussing the dynamometer tests conducted for jeepneys using B5 fuel.

There were other presentations but unfortunately, I wasn’t able to attend these as lectures were spread among various venues at the college. That’s often the hang-up of having parallel sessions during these colloquiums. Nevertheless, it is nice to know that transport remains a popular subject for these lectures.

The Philippines’ National EST Strategy – Final Report

Friends and some acquaintances have been asking about whether there is a master plan for sustainable transport in Philippines. There is none, but there is a national strategy that should serve as the basis for the development and implementation of a master plan, whether at the national or local level. This strategy was formulated with assistance of the United Nations Council for Regional Development (UNCRD) through the Philippines’ Department of Transportation and Communication (DOTC) and Department of Environment and Natural Resources (DENR), which served as the focal agencies for this endeavour. The formulation was conducted by the National Center for Transportation Studies (NCTS) of the University of the Philippines Diliman. For reference, you can go to the NCTS website for an electronic copy of the National Environmentally Sustainable Transport Strategy Final Report.

A study on a long-term transport action plan for ASEAN

The National Center for Transportation Studies of the University of the Philippines Diliman participated in the project “Study on the Long-Term Action Plan for Low Carbon Transport in ASEAN.” The study was funded by the Nippon Foundation and implemented by the Institution for Transport Policy Studies (ITPS) and Clean Air Asia with experts coming from ASEAN countries including Indonesia, Malaysia, the Philippines, Thailand and Vietnam, and Mizuho of Japan, which led the development of the Backcasting and Visioning Tools employed in the study. Detailed case studies were performed for Indonesia through the Universitas Gadjah Mada and for the Philippines through the University of the Philippines Diliman.

The Final Symposium for the study was held last February 20, 2014 at the Hotel Okura in Tokyo, Japan. A link containing information on the study, the symposium program, information on speakers, and presentation files are hosted by the Japan International Transport Institute, which is affiliated with ITPS.
