To start the year 2022, I’m sharing another article by Todd Litman. I thought this was a timely one as this is basically about transport equity and the results despite competent planners and perhaps good intentions.
Litman, T. (December 21, 2022) “Good Planners: Bad Outcomes. How Structural Biases Can Lead to Unfair and Inefficient Results,” Planetizen, https://www.planetizen.com/blogs/115621-good-planners-bad-outcomes-how-structural-biases-can-lead-unfair-and-inefficient?utm_source=newswire&utm_medium=email&utm_campaign=news-12232021&mc_cid=35d4ce69aa&mc_eid=9ccfe464b1 [Last accessed: 12/27/2021]
There should be similar studies for the Philippine case. We need to understand and correct bad practices including those related to an over-reliance to what is referred to as “old school” practices (i.e., “nakasanayan na”, “ginagawa na noon pa”, and so on), which is what young engineers and planners are taught by the “old boys” in certain agencies as an initiation of sorts if not part of their ‘continuous orientation’ at these offices.
We end the year with an article from Todd Litman via Planetizen. The topic is something that we really need to ponder on as we or if we are to move towards more sustainable transportation for our cities and municipalities. The experiences during this Covid-19 pandemic should have provided us glimpses of how it could be if we put active and public transport above automobile dependence or car-centricity.

I’m sharing this article on housing in Montreal. The relevance is basically related to urban planning and its implications to transportation.

I’ve shared and posted a few articles on housing before. These include my own opinions about housing and its close links to transportation. Having lived in Japan and Singapore, I I saw first hand how concepts like transit oriented development (TOD) and socialized housing were implemented. I think there’s a lot we can learn but haven’t so far from these examples that will also address problems associated with sprawl including the lagging development of transportation systems to cover the increasing demand.
Much has been said and written about how electric vehicles could be the game changer for transport. Those include supportive material and also those that are more critical and provide different perspectives to EVs. Here is another article that discusses EVs in the context of the avoid, shift, improve framework:
O’Riordan, V. (November 30, 2021) “Electric vehicles aren’t a fix for carbon emissions. These 3 things need to change—fast,” Fast Company, https://www.fastcompany.com/90700832/electric-vehicles-arent-a-fix-for-carbon-emissions-these-3-things-need-to-change-fast [Last accessed: 12/17/2021]
There’s a recent article about the environmental impacts of manufacturing EVs including the batteries used by these vehicles. I will share that in another post.
We start December with another shared article. Here is another excellent article from Todd Litman about roadway expansions and induced demand:
Litman, T. (November 28, 2021) “The Roadway Expansion Paradox,” Planetizen.com, https://www.planetizen.com/blogs/115395-roadway-expansion-paradox?utm_source=newswire&utm_medium=email&utm_campaign=news-12022021&mc_cid=89cc0b2638&mc_eid=9ccfe464b1 [Last accessed: 12/3/2021]

I’ve written about how we should not be trying to isolate transportation as if it is singly at fault for the transport and traffic mess many of us are in at present. There are many factors affecting travel behavior including mode choice. Travel distances, travel times and mode choices are not a consequence of transportation system (including infrastructure) alone. Land development and pricing especially those pertaining to housing are critical in how people decide where to live. These are intertwined with transportation and can be quite complex without the proper data or information to help us understand the relationship. That understanding, we are to assume, should lead us to the formulation of policies intended to correct unwanted trends and perhaps encourage more compact developments that are closer to desirable concepts such as the 15-minute city.
Here is an interesting article to enrich the discussion on this topic:
Dion, R. (October 28, 2021) “Coupling Housing and Mobility: A Radical Rethink for Freeways,” Planetizen.com, https://www.planetizen.com/features/115126-coupling-housing-and-mobility-radical-rethink-freeways?utm_source=newswire&utm_medium=email&utm_campaign=news-11012021&mc_cid=85ec2b565f&mc_eid=9ccfe464b1%5BLast accessed: 11/3/2021]
The first thing that came to my mind are residents of northern and southern Metro Manila and the surrounding provinces. Many chose to buy houses there and beyond (i.e., Bulacan, Laguna and Cavite) and yet work or study in Metro Manila CBDs like Makati, Ortigas and BGC. And they do use the tollways (e.g., NLEX, SLEX, CaviTEX, Skyway) to get to their workplaces and schools.
This is also a relevant and timely topic in the Philippines as many cities are already headed for sprawls that will inevitably put more pressure on transportation infrastructure development that usually leans towards car-oriented projects (e.g., road widening, new roads, flyovers, etc.) rather than people-oriented ones (e.g., modern public transportation systems, bikeways, pedestrian infrastructure). Note that only Tokyo has developed an extensive enough railway system to cover the sprawl that is the Tokyo Metropolitan Area, which if interpreted loosely also includes Yokohama, Kawasaki and Chiba in the sprawl. No, we cannot build as fast to have as dense a railway network as Tokyo’s or other cities with similar rail systems. And so we have to figure out another way to address this problem.
The National Building Code (NBC) of the Philippines stipulates the minimum number of parking spaces or slots per type of establishment and intensity of development (i.e., according to area or other parameters). These established provisions are generally called parking minimums. The NBC’s provisions are already archaic by current standards and need to be revised but not in the way it was apparently developed. The NBC needs supporting evidence from studies (are there any dependable ones around?) on parking requirements including those for bicycles and motorcycles. These should clearly not include or impede the requirements of pedestrians. And local government units must be required to enforce these NBC provisions.
Here is an article that discusses the proposal for new limits on parking, particularly in large developments in Boston, Ma. in the US:
The article points to this one:
City of Boston (September 20, 2021) Maximum Parking Ratios, https://www.boston.gov/departments/transportation/maximum-parking-ratios [Last accessed: 10/19/2021]
I must admit that I still have to do a lot of reading on this. There are some who are calling for the abolition of parking minimums but you just can’t do this so abruptly without understanding the context and current set-up. We are not Boston or San Francisco or Hong Kong or Singapore in terms of the transport infrastructure and services and the progressiveness of policies including those governing or covering housing and other factors that come into play with transportation. Sprawl and the resulting pressures (requirements for efficient travel) on the transportation system is not transport’s fault or responsibility alone like what some articles or infographics make it appear to be. It is very much about land use and land development, and the policies and the political economy behind these developments.
I did some work on long term action plans on low carbon transport for the ASEAN region before. We were able identify many of interventions that were being implemented as well as those that can be done to reduce transport emissions. Such reductions for the region would ultimately contribute to alleviating global warming. Unfortunately, while ASEAN is a significant contributor to emissions, it pales in comparison to emissions by individual countries like China and the US. If these two and others in the industrialized world do not commit to reducing their emissions, all work will come to naught. Here is an article that serves as a pre-event write-up for COP26, a major climate summit that will be held in Glasgow in the coming days.
Induced demand or traffic is a popular topic these days thanks to the proposal of a private company to build an elevated tollway along the Pasig River. The topic is also much in circulation the past few years as the DPWH’s part in the government’s Build, Build, Build program has road widening as a major component. There are many completed, ongoing and planned projects across the country that involves road widening, particularly increasing the number of lanes of typical national roads from 2 to 4, not counting the shoulders (paved or unpaved). The results are mixed as there are roads that definitely required capacity increase in the form of additional lanes, and there were roads that did not require them. The latter were still expanded and perhaps the agency did so because their key performance indicators basically obliged them to undertake such projects regardless of the need. Somehow, these were justified and yet there were and are many questionable road widening projects especially those that involved the cutting of decades if not century old trees (e.g., the Kamatchile and Acacia trees that used to line up long sections of national roads in Tarlac are no more) or the demolition of heritage structures such as houses.
A came upon this article about an “Induced Demand Calculator” developed in the US. I have not gone through the calculator itself but such a tool could be quite useful in quantifying the impacts of road widening while pushing for other options to improve transportation and traffic that is not the typical “solving traffic” type of approach. Here is the article in Streets Blog:
I am not aware if there are similar tools being developed here. Such a calculator will require data from various sectors including construction costs, operations and maintenance costs, value of time and current and projected vehicular and person trips that can be translated into traffic volumes.
