On solving the inequality problem in cities

Here is another quick share of an article that is timely and relevant not just now but for years (maybe decades?) to come:

Grossman, D. (2020) “New Study Proposes a Mathematical Solution to Big Cities’ Inequality Problem,” Inverse, [Last accessed: 9/15/2020]

I will just leave it here for future reference but to summarize, the article explains how cities should be planned or replanned based on the distribution or redistribution of certain facilities like hospitals, banks, schools, supermarkets, and parks. It argues that there is an optimum location for these in relation to where people live and work. If properly planned, travel distances and times can be significantly reduced.

On bicycles slowing down cars

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!, [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).

On making roads safer for students

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:

Transportation research makes the road safer for students to get 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.

On designing street for bicycles

There have been a lot of discussion both online and offline about coming up with bike lanes for Metro Manila. Already, there are examples of pop-up bike lanes in some cities while others have had bike lanes and bikeways constructed years ago (e.g., Marikina and Iloilo). While agencies like the DPWH and MMDA have formed technical working groups (TWG) for bike facilities, the perception is that these are moving too slowly (dragging?) and have not produced any gains in so far as design recommendations or guidelines are concerned. Just how important are such guidelines and perhaps at the beginning, context setting, to come up with suitable designs incorporating cycling (and walking) rather than the usual car-centric set-ups? Here’s another article I am sharing that argues for these street designs:

On mass transit and active transport

I recently gave a talk on transport in the new normal. There are a lot of materials that you can refer to if you want good visuals for a presentation. It helps to capture the attention and maybe the imagination of your audience, which in this case was varied. While I assume many to be in the physical, chemical & social sciences, and engineering, I knew that there were also people from media and those who were just interested in the topic. And so I made sure there were a lot of infographics mixed in with bullet points to drive the message clear about mass transit systems being the backbone of transport in highly urbanized cities, conventional transit like buses and jeepneys supplementing and complementing these, and active transport enabled and encouraged as a safe option for many.

I wasn’t able to include the following graphic shared by a friend advocating bicycle use especially for work and school trips. The following graphic comes from TUDelft, which is among the major universities in the forefront of research in transit and cycling. Clicking on the graphic will take you to their Facebook page and more links to their programs.


Note the essential information relating bicycles and transit in the graphic. Do we have similar data in the Philippines (or at least for the National Capital Region)? I hope this stirs interest for research work. There are a lot of topics to take on including even data collection to capture the information required for substantial studies on cycling, transit and their relationship.

On urban planning resources or references for the pandemic

I am posting for reference this article compiling helpful references for urban planning in the context of the COVID-19 pandemic. Most of the references listed are based on the US experience and I am sure there is already a wealth of information coming from other countries as well including those that have been successful in mitigating the effects of the pandemic.

Reference on Bicycle Facility Preferences and Increasing Bicycle Trips

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).

On walking, running and cycling for exercise during the Covid-19 pandemic

We had been walking in the early mornings prior to the so-called “total lockdown” implemented by our Barangay. There were others like us in our community who walked, jogged or cycled during the same time we took our walks. However, we all practiced physical distancing and used masks while outdoors. We could afford to do this because the village where we resided in had relatively wide streets and there were few houses and residents compared to other residential areas. In our case, we usually walked in areas where there were even fewer houses and people. It is highly unlikely we could get Covid-19 during our morning walks. Afternoons were different as we observed more people going around including those who appear to be joyriding with their motorcycles.

Is there actual evidence that walking, jogging, running or cycling actual aid the spread of Covid-19? So far, there isn’t and what we have are mostly simulations. Yes, simulations like those that appear in articles that are going around the internet; often shared in social media. Here is a more informative and objective article about this topic that articulates more the importance of physical activity (i.e., in the form of walking, jogging, running or cycling) in combatting the virus while also emphasizing the need for social or physical distance and the use of masks:

Niiler, E. (2020) “Are Running or Cycling Actually Risks for Spreading Covid-19?”, Wired, [Last accessed 4/15/2020]


I appreciate the efforts of those in our Barangay to make sure no one gets infected (there are zero incidents so far). However, sometimes the overeagerness seem to trump the need to practice common sense in these times. I believe there is a need to make an even bigger effort to ensure people are able to maintain physical and mental wellness through exercise or activity. I believe we are in a community where people are educated, aware and responsible enough to make this work.

EASTS 2019 Conference

The 13th International Conference of the Eastern Asia Society for Transportation Studies (EASTS 2019) is currently underway. This conference is hosted by the domestic society of Sri Lanka from September 9-11, 2019. The conference was almost canceled or relocated due to the safety and security concerns following the bombings in Colombo last April. After assurances by the organisers plus the full support from government, the conference was decided to push through in Colombo.
