On phantom congestion

I’ve talked about phantom congestion in my class lectures and training modules but have always explained it through figures and diagrams I usually draw on the board as I discuss the topic with my students or trainees. Here is a very informative, very visual explanation of what typically happens along many roads and how there is congestion when there seems to be no reason at all for these traffic jams:

Have you experienced these phantom traffic jams yourself?

Painted lines are not enough for bike lanes

From the experiences of many biking or trying to bike in the Philippines, painted lines are not enough for bike lanes. Only recently, cyclists using bike lanes that did not have any physical barriers to deter motorists from encroaching have been involved in crashes, with at least a couple being reported as fatal for the cyclists. Here is an article on what cyclists need in order to ensure or at least improve the safety of their commutes.

Commuters on bicycles along the Marcos Highway bridge bike lane

Are there differences regarding cycling in different countries? From a somewhat cultural-behavioral perspective, perhaps there are studies (though I am not aware of them yet) about how peoples from different countries or cities behave with respect to cyclists whether or not there are bike lanes designated for the latter’s use. I recall my experiences cycling in Japan and drivers are generally respectful of cyclists on the roads. Pedestrians, too, are very tolerant of cyclists on the sidewalks or designated areas for walking. Of course, the cyclist would have to do their share of respecting others’ spaces, too, and should behave and position themselves accordingly while traveling.

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:

The problem with public transport in the Philippines…

There is a collage of two photos, one taken in 1975 and another in 2019, showing buses that managed to squeeze themselves into a jam. The 1975 photo was taken at the ramp of the overpass near Liwasang Bonifacio (Quiapo, Manila). There is a commentary describing the photo that attributes ‘monstrous daily traffic jams’ to the behavior of Filipino drivers. Special mention was made of public transport drivers and the photo showed proof of this. This was 1975 and motorization had not reached the levels we are at now so the

The problems pertaining to driver behavior persist today and probably even worsened along with the general conditions of traffic in Philippine roads. I say so since the volume of vehicular traffic has increased significantly from 1975 to the present and there are much more interactions among vehicles and people that have led to a deterioration of road safety as well. Traffic congestion and road crashes are asymptomatic of the root causes of most of our transport problems. And so far, it seems we have had little headway into the solutions. The photos speak for themselves in terms of how many people can easily put the blame on poor public transport services despite the fact that cars are hogging much of the road space. And what have authorities done in order to address the behavioral issues that lead to these incidents?

Someone joked that the guy in the 1975 photo who appeared to be posing in disbelief of what happened is a time traveler. The 2019 photo shows a similar guy with a similar pose though with more people around. Maybe he can tell us a thing or so about what’s wrong with transportation in the Philippines and provide insights to the solutions to the mess we have.
