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.

Why cycling or bicycles are good for the economy?

You saw that meme shared in social media where they say “why bicycles are bad for the economy”? There’s some humor there but it doesn’t necessarily convince many people to support cycling or biking over motor vehicle use.

Here goes one and note the logic:

“Cycling or bicycles are good for the economy because…it helps reduce car use/dependence. That means less dependence and expenses to fossil fuels. That means more money available to the household for more important stuff like food, homes and education.”

Can you come up with something like that?

On pandemic travel patterns and the future

Here is a recent article on travel patterns as influenced by the COVID-19 pandemic.

Bliss, L., Lin, J.C.F., and Patino, M. (2020) “Pandemic Travel Patterns Hint at Our Urban Future,” Bloomberg CityLab, [Last accessed 6/19/2020].


Are these travel patterns similar to those of our cities and municipalities in the Philippines? Or were there a different reactions or outcomes considering local factors including perhaps cultural aspects?

Traffic is back to “normal”

Traveling to the office last Monday, I could not help but notice the long lines of cars along Ortigas Avenue’s westbound lanes and Katipunan’s southbound lanes. Without adequate public transportation, people have few options for their commutes. Walking from home to workplaces is feasible only for those who live relatively near their workplace (perhaps up to 5km distance?). Cycling may be considered but not everyone can bike beyond 5km, what more for 10km+ commutes. And for both cases, there are just so many obstacles (and I’m not just fault-finding here) like a lack of sidewalks and bike paths to ensure safe walking and cycling.

Traffic congestion along Felix Avenue in Cainta towards Cainta Junction (with Ortigas Avenue Extension) – these are┬ámostly outbound traffic likely coming from the residential subdivisions along Felix Avenue and heading to workplaces in Pasig, Mandaluyong, Makati and Taguig. They will likely take Ortigas Avenue to connect with other major roads such as C-5 and EDSA to get to their destinations.


The DOTr and the LTFRB have released guidelines for safety and the prevention of the spread of the COVID-19 virus. Yet, they have moved quite so slowly to bring back public transportation to address the demand for it and to be able to discourage or restrict car usage in the “business-as-usual” or “old normal” sense. Public transportation is critical if we are to transform transportation during this transition from the lockdowns. Granted, the government probably wants to use the situation to effect its modernization plans but it is one thing to take advantage of the opportunity and another to be an opportunist considering the vulnerabilities of the transport sector after it endured 3 months of shutdown. The moral and right thing to do is to bring back public transport and give incentives for it to thrive and perhaps transform or upgrade by themselves rather than force the situation at the expense of commuters.

Infographics: Infection Risk Classification of Transport Modes Post-ECQ

The infection risk table I posted a few days ago was improved into the following infographics:

COVID-19 Infection Risk Assessment of Transport Modes

I posted about the work we have been doing to assess the infection risk (i.e., spread of COVID-19) for various modes of transport considering the transition of many areas including the National Capital Region (NCR) to the General Community Quarantine (GCQ). The work was undertaken through the Transportation Science Society of the Philippines (TSSP), which is under the umbrella of the Eastern Asia Society for Transportation Studies (EASTS).┬áHere is the outcome in the form of an “Infection Risk Classification of Transport Modes or Vehicle Types” developed by a core group of public transportation and road safety specialists among its members:

Note again that this is the product of a rapid assessment using the mentioned criteria and factors. It is a qualitative assessment and a quantitative one, given the data, would obviously been preferred. Moreover, this is an assessment for risk of infection rather than for road safety. In the “old normal”, for example, cycling and motorcycle use may have a higher risk in traffic given traffic mix, human behavior and lack of facilities to make these modes safe.

Assessing the risk of infection from the transport safety perspective

My colleagues and I have been developing a risk assessment table for land transport modes to be submitted to the UP COVID-19 Response Team. We did a rapid assessment using mainly concepts from road safety.

The concepts are fairly simple. Risk assessment can be based on the likelihood of contracting the virus gauged from certain exposure factors. Exposure estimation may be quantitative where metrics are applied and data collected for the analysis. Estimation may alternatively qualitative based on experiences, perceptions, expert opinions, etc. but subject to logic (e.g., careful deduction). In road safety, for example, these factors may be defined as three: time, distance and volume.

Time exposure can be determined using travel time as a metric. Longer the travel times mean higher exposures for a commuter. Higher exposure translate to a higher likelihood that a person may become involved in a road crash. Thus, a commuter traveling for 1 hour, one way, will have a higher likelihood of being involved in a crash compared to another traveling only 10 minutes even assuming that both use the same mode of transport. Applied to the risk of viral infection, longer commutes may mean people can have higher exposure to potential carriers of the virus.

Distance exposure can be determined using travel distance as a metric. Longer travel distances mean higher exposures for a commuter. Higher exposure again translate to a higher likelihood that a person may become involved in a road crash. Thus, a commuter with a travel distance of 10 kilometers will have a higher likelihood of being involved in a crash compared to someone traveling only 1 kilometer. Applying this to the risk of viral infection is similar to the previous case for time exposure even when assuming the same mode of transport.

Volume exposure can be determined using both the volume of vehicles as well as the number of passengers inside the vehicles. The more vehicles or people you have on the roads interacting, the higher the likelihood of one becoming involved in a crash. It can also be argued that riding public transport in high volume, mixed traffic makes a passenger have a higher likelihood of being involved in a crash. Again, applying this to the risk of viral infection, it should be easy to understand why physical distancing is necessary in vehicles as well as outdoors when walking or cycling. It should also extend to having less vehicles on the road to further reduce the likelihood of spreading the virus.

In the real world, we cannot isolate each factor from one another. Instead, we have to contend with all three combining to create various scenarios. Along expressways, for example, the volume of vehicles might be high and so are distances. Time exposure can be lower due to high speeds. Yet high speeds can contribute to increased likelihood of crashes. Meanwhile, traffic congestion has all the ingredients for maximizing the likelihood for crashes and, by extension, viral infection. Long commutes (by time and distance) plus high volumes of people and vehicles combine to create the worst case scenario from the perspectives of both road safety and infection, which are both public health issues.

Next – Why we should not return to the old normal…

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.

On the proposed single bus route along EDSA

A friend posted this on social media as news came out about the government’s statement on its considering a single bus route for EDSA. EDSA, of course, is Circumferential Road 4 and perhaps the busiest road in Metropolitan Manila in terms of volumes of people and vehicles traversing this road. Public transportation along EDSA is mainly by buses and the MRT Line 3. Line 3’s capacity is already diminished despite the high demand for it mainly because of the number of train sets that are currently in operation. Buses, meanwhile, are split among the many routes converging along much of EDSA. These routes are shown in the map on the left where you can see the overlapping routes that have various end points.


Of course, it is best to read the Final Report of this study. That way, one is able to see the overall context for this section that is part of the concluding part of the report. I recall that the consulting team from UP was able to map the routes of other public utility vehicles like jeepneys and UV Express from that time. Perhaps the DOTr still has a copy somewhere? The NCTS Library in UP Diliman is currently closed so one may have to search the internet first for a copy of the study or perhaps snippets of it here and there. Perhaps related to this is a proposal to revive (or maybe the right word is ‘resurrect’?) the now defunct Metro Manila Transit Corporation or MMTC that used to dominate EDSA and other major roads in direct competition with the few private bus companies during its heydays as well as the jeepneys.

On the DOTr GCQ Guidelines for Public Transportation – Road Sector

I just wanted to post, share and document here the DOTr’s Guidelines for Public Transport Operations for areas under General Community Quarantine (GCQ). The images are self explanatory so I will not discuss these nor will I offer a critique at this point. The following are public and posted on DOTr’s social media pages (i.e., Facebook) and have been shared and circulating among the public. I also post it here for future reference as I do to many other references like articles and infographics.
