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). Here 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.
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…
Here is another article I am sharing (re-sharing?). I have seen or read a lot of posts on social media about how we should not go back to the car-centric traffic before the Enhanced Community Quarantine (ECQ) and its variations. I do agree with this point. However, I take reservation about how some people seem to be resorting to car-shaming rather than be more proactive and progressive about coming up with strategies and/or plans that I hope would be evidence-based or supported by valid data. As the article states, “it takes more than car-shaming to change car use”:
Jaffe, E. (2020) “It takes more than car-shaming to change car use”, Medium, https://medium.com/sidewalk-talk/it-takes-more-than-car-shaming-to-change-car-use-107e28ccb2cf [Last accessed: 4/29/2020]
A key message from the article: “People are most open to changing their travel habits during major life events, such as a move. But even a well-timed message isn’t enough.” Perhaps the opportunity is here now to reform our transportation system. But that will take a lot of will or effort from all sectors most especially the national agencies (e.g., DOTr, DPWH) and local governments who have the authority and responsibility to implement changes. These changes include the assignment of exclusive lanes for bicycles, public transport and logistics while restricting car use. There are also other elements that need to be in place as we transition into the so-called “new normal” and so there will be a lot going on among the sectors or parties collaborating or interacting for transportation. Hopefully, there are context-sensitive strategies that will be adopted and implemented in order for everyone to transition more efficiently and effectively. And as they say…life goes on.
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, https://www.wired.com/story/are-running-or-cycling-actually-risks-for-spreading-covid-19/?bxid=5bd6761b3f92a41245dde413&cndid=37243643&esrc=AUTO_OTHER&source=EDT_WIR_NEWSLETTER_0_DAILY_ZZ&utm_brand=wired&utm_campaign=aud-dev&utm_mailing=WIR_Daily_041420&utm_medium=email&utm_source=nl&utm_term=list1_p4 [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.
I was reviewing materials for my classes now that the latter have been suspended and we are switching to online teaching. I came upon the topic of level of service (LOS) for pedestrians – for walkways and sidewalks to be exact. Following is the LOS table for walkways and sidewalks (platoon-adjusted) with my note, and an illustration of walkway LOS thresholds with my annotations. The recommended minimum social distance is 1 meter. That translates to a space of 3.14159 square meters if we assume a circular area around a person.
Platoon-adjusted means people are moving and grouped according to the speed of a lead person or persons dictating their walking speed.
I annotated the illustration to show the minimum pedestrian spacing, the ideal spacing, and situations when the desired social distance is not achieved.
The big question now is if we can achieve the minimum given the mostly inferior pedestrian facilities we have in the country. Do you know of any areas where this can be achieved? BGC? Trinoma? MOA? UP Diliman Campus? Iloilo City’s Esplanade?
The National Transport Policy is out and there’s a lot of buzz about the wording of the policy. NEDA released the following infographics on their official Facebook page:
Definition of what the policy is about
Hierarchy of transport modes (note the emphasis on walking and cycling)
Checklist for programs and projects: I am already anticipating what proponents will be writing to justify projects according to this checklist.
I will reserve my commentaries for future blogs. There is really a lot to discuss about this policy and how it will implemented (properly or improperly), There are lots of different ideas, advocacies, interests and agendas on transportation that come into play here. And we can only hope that the policy and its implementing rules and regulations will be clear enough (not vague as to have so many loopholes) for this policy to effect transformation and inclusive and sustainable development.
The connections between transit stations in Singapore show us examples of how to encourage people to walk long distances. The links, mostly underground, are interconnected with branches to common exits to hotels, office and residential buildings. These are basically transit malls lined with cafes, restaurants and shops. There are even gyms (e.g., UFC) and play venues along some connections.

The connection is lined with restaurants, cafes and shops
Singapore’s underground connections reminded me of similar structures in Tokyo and Yokohama. You can just walk underground and come up near your destination. This is especially advantageous and comfortable during the summers when the hot weather becomes a detriment to walking outdoors. Underground transit malls or connections are usually air-conditioned or air is pumped into them for ventilation. As such, temperatures are significantly lower compared to the surface/ground. Will we have similar facilities/developments here in the Philippines and particularly in Metro Manila once the MM Subway is developed?
The recent trip to Singapore was like a sentimental journey for us. We had lived in the Lion City for almost 2 years and consider this a second home (actually a close third for me because I consider Yokohama as a second home having lived there for 3 years). Among the things we truly missed about Singapore aside from friends (many of whom have already moved to other countries) and food were the public transport and the walking. Singapore is a walkable city and the excellent public transport along with the land use planning has allowed healthier commutes for people.
The environment along Orchard Road is inviting and conducive for walks.
Wide sidewalks can accommodate more people and don’t make it feel so crowded even during the peak hours.
It was easy to log more than 10,000 steps per day in Singapore. In fact, I was happy to have walked an average of 11,000+ steps per day for the 3 days were there. One could only hope we can have similar infrastructure in the Philippines.
More on walking and public transport in Singapore soon.
The sidewalks around the University of San Jose Recoletos in Cebu City are named Paseo de Recoletos and Paseo de San Jose. Here are a few photos on Paseo de Recoletos.
Arcade-type walkway along the perimeter of the University of San Jose Recoletos. This part is the Paseo de Recoletos along Magallanes Street and across from the Freedom Park Market. The other is Paseo de San Jose but is not wholly covered. The latter is along P. Lopez Street.
The Paseo leads to the church of Our Lady of Mt. Carmel, which is on the second level from the ground.

Another view of the Paseo de Recoletos
The main gate of the USJR is at the corner of Magallanes and P. Lopez Streets. The photo capture the view towards P. Lopez and the side of the university along this street is Paseo de San Jose.
Frontage of Our Lady of Mt. Carmel Parish Church, which is integrated with the main building of the university, which is run by the Order of Augustinian Recollects (OAR).
Scenes along the Paseo de Recoletos included overloaded jeepneys, motorcycle taxis and various vendors both mobile and those who’ve set up shop across the street.

Scenes like these are common in many Philippine cities especially the old ones that have narrow streets and have retained much of the commerce in many areas around the city centre. It gives you a glimpse of the marketplace and commerce before the arrival of the large malls. Of course, there are what are already termed as malls around the area but these are more like large department stores than the types of SM City, Ayala Center and Robinsons Place.
Last month when we were in Cebu to coordinate with our counterparts at the University of San Jose-Recoletos (USJR), I took some quick photos of the sidewalk scenes near the university. We stayed at a nearby hotel so that meant we only needed to walk to/from USJR for our meetings. Here are some of those photos.
Many buildings in the downtown area have designs where sidewalks are practically covered, protecting pedestrians vs. the elements. This alludes to arcade design architecture you find in many old cities’ downtowns including Manila, Iloilo and Bacolod.
There are many shops and stores at ground level. Depending on the area, there will be hardware stores, electronic stores, school supplies and others.
Along some streets, one will find makeshift stalls occupying the road itself. I assume these are allowed by the city along certain streets.
Typical street vendor with his mobile store. Fruits, local delicacies and snacks, and refreshments are popular.
I believe these scenes reflect on the character of the city and gives the visitor a view of life in the downtown area of the city, which in this case is Cebu, the oldest city in the country. I will be back in Cebu soon and will be taking more photos around downtown. I’ll be posting these, too.
