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.
I’m sharing a recent article that laments about how transport departments in the US seemingly don’t understand the concept and phenomena of induced demand. Is it really difficult to understand or are transport officials including highway planners and engineers deliberately ignoring what’s staring them in the face?
Zipper, D. (September 28, 2021) “The Unstoppable Appeal of Highway Expansion,” Bloomberg City Lab, https://www.bloomberg.com/news/features/2021-09-28/why-widening-highways-doesn-t-bring-traffic-relief [Last accessed: 10/10/2021]
The topic in the article is very much applicable to our own Department of Public Works and Highways (DPWH). The DPWH’s key performance indicators (KPIs) need to change from the typical “kilometers of road constructed” or “lane-kilometers of roads widened” to something like “travel time between points A and B”. Agencies like the DPWH always like to claim they are for solving traffic congestion but we already know widening roads just won’t cut it. It has to be more comprehensive than that and involve the entire transport system rather than just a part (i.e., the road). And it has to be a collaborative effort with various other agencies like the Department of Transportation (DOTr) and local government units. Unfortunately, too, these agencies like the DOTr and those under it, and many (not all) LGUs also like to go at it solo so we end up with piecemeal solutions that are also often out of context.
There’s a nice article recently published on The New York Times. It’s about how cities have been rethinking and developing their transit systems in light of climate change and the pandemic. Here is the article:
An interesting part of the article is on the call for the return of trams or street-level trains. These are very similar to the tranvia that used to be the preferred mode of public transport before World War 2. Would that be possible to build now in Metro Manila? Perhaps it would be a bit more challenging given the development but there are definitely corridors or areas where you can have trams…if the government wanted to. Among those would be along the Pasig River if the development will be similar to the esplanade and enough ROW can be acquired and allocated for these street-level transport. There is also the Botocan ROW, which we actually studied many years ago for Meralco, for the feasibility of a street-level transit system stretching from Katipunan to Quezon Institute. It could have been the revival of Meralco’s rail division of old.
What do you think?
I have shared articles and briefly written about the concept of the 15-minute city on this blog. Here is another discussing how a 15-minute city is defined:
(February 8, 2021) “Defining the 15-minute city,” Public Square, https://www.cnu.org/publicsquare/2021/02/08/defining-15-minute-city [Last accessed: 8/10/2021]
Here is an image from the article:
Again, it is important to contextualize these concepts. I share these as references and topics for discussion. Of course, I have my own opinions about this and I have written about those in previous posts. I guess in the Philippine context, we can include the pedicab or non-motorized three-wheelers in the discussion. These are also very popular modes in many cities and municipalities despite their being also prohibited along national roads like their motorized counterparts. It would be nice to have more visuals in the form of maps that show travel times for essential destinations or places like hospitals, markets, grocery stores, workplaces and, of course, homes. I assume there is at least someone, somewhere who perhaps have made multi-layer maps of this sort and attempted to related them along the lines of this concept of a 15-minute city (or perhaps the even older “compact cities”).
Since the Philippine government is engaged in its Build, Build, Build infrastructure development program, and agencies like the DPWH and DOTr often or regularly refer to what’s happening in the US in terms of projects, guidelines and standards, I am sharing the following article on the principle
Marshall, A. (March 18, 2021)“What Are the Five Principles of Good Infrastructure?” Governing.com, https://www.governing.com/community/Five-Principles-Good-Infrastructure.html [Last accessed: 4/5/2021]
Despite obviously being an article about US infrastructure in the context of the new administration there, there are just too many takeaways or relevant information here that applies to us and how we are developing and maintaining our infrastructure. To quote:
“First of all, cost matters. The evidence is pretty clear now that we pay several times more than other advanced nations to build transit infrastructure, particularly tunnels, and possibly highways as well. It appears we pay too much to build public parks.
Second, time matters. We still get estimates for infrastructure projects whose construction stretches into decades, when it should be a few years. Time relates to cost. Adding time makes projects more expensive.
Third, connections matter. Whether it’s a light-rail line joining up to a bus line, or an interstate exit linking to a town, the connections between infrastructure systems are important. High-speed rail lines need to intersect seamlessly with the cities they serve. Infrastructure can’t be designed in a vacuum. Urban planners and designers should be at the top of the infrastructure food chain, so that transportation and other departments work for comprehensive visions.
Fourth, design matters. Western Europe has been erecting light, airy bridges for decades, while we have continued to build heavy concrete slabs. This is changing, but we lag behind other countries in the design quality of everything from bridges to subways.
Finally, ownership matters. Even the best-designed and swiftly built infrastructure will turn bad if we give one or two private companies total control over them. As we use private companies for broadband, cable, telephones, data management and the power that runs our homes, we need to remember this. When we can’t (or won’t) have public systems, then the private ones need to be carefully managed.”
To what extent do you think these principles apply to our case?
Here is an article discussing the downside(s) of the 15-minute city; particularly its adoption without understanding first and setting the context for the concept:
O’Sullivan, F. (March 3, 2021) “The Downside of a 15-Minute City,” Bloomber CityLab, https://www.bloomberg.com/news/articles/2021-03-02/the-downsides-of-a-15-minute-city [Last accessed: 3/20/21]
Some people are pushing very much the same concept for quick adoption in the Philippines without again contextualizing it. I feel these people are detached or choose to be so perhaps as they seek shortcuts to achieve what they believe should be the way cities and municipalities are laid out in the country. But wait…don’t we already have 15-minute cities in the Philippines? I will be writing about that soon…
I am currently involved in a project concerning child road traffic injury prevention (CRTIP). The topic of road safety is also close to my heart since a beloved aunt died due to injuries sustained after being hit by a jeepney. She was in great health and walked almost daily between our home in Iloilo and the church to hear Mass. Children and senior citizens are among the most vulnerable road users and so I believe we must address their needs more than able-bodied adults. That would probably make our communities safer and friendlier to most people. Here is an article that tackles planning for communities from the perspective of children and families:
Litman, T. (March 9, 2021) “Planning communities for children and families,” Planetizen.com, https://www.planetizen.com/node/112498?utm_source=newswire&utm_medium=email&utm_campaign=news-03112021&mc_cid=5a75b816a6&mc_eid=9ccfe464b1 [Last accessed: 3/14/2021]
To quote from the article:
“Here is a summary of child-oriented urban design features:
Children need opportunities to join a loose social group of other children without a formal—or prearranged—invitation to play.
Children need access to safe, uninhibited outdoor play to support their physical and mental health. Outdoor play should include opportunities to interact with the natural environment—finding bugs, smelling flowers, playing in puddles, or collecting objects—without the need for excessive rules, oversight, or segregation.
Children need environments that are safe from traffic, pollution, and undue physical or social hazards, including safe routes to and from school and local playgrounds, allowing them to travel throughout their neighbourhoods safely in order to develop confidence, resilience, and independence.
Children need private spaces for themselves and their friends, including tree houses, forts, or clubhouses that are close to home yet away from public view. 5.
Children need stable, appropriate, and affordable housing that provides them with private space to rest, study, and play.
Children need local access to appropriate early childhood education, child care, and community schools.
Children benefit from the opportunity for their parents to work locally.
Children benefit from walkable communities, with infrastructure for safe walking, cycling, and recreation.
Children benefit from diverse, multi-generational communities, where they can interact with—and learn from—children, adults, and seniors of all races, religions, cultures, and incomes.
Children should be given an opportunity to effectively and productively participate in decision-making processes.”
There’s this recent article on housing that presents and discusses lessons from Singapore housing that
Fischer, R. (February 2, 2021) “Singapore Housing Lessons for the Biden Administration,” Planetizen, https://www.planetizen.com/node/112077?utm_source=newswire&utm_medium=email&utm_campaign=news-02082021&mc_cid=4fac9821d0&mc_eid=9ccfe464b1 [Last accessed: 2/15/2021]
I’m not an expert on housing but I’ve experienced living in Singapore. Here’s a photo of the wife as she walked ahead of me on our way to the MRT station near our place back in 2012. One of the factors we considered when we chose this place for our residence was its proximity to the orange line station that meant only one ride (no transfers) between our home station and the station closest to the wife’s office. We could also take the train to the nearest mall if we didn’t feel like walking 15 minutes.
To quote from the article:
“…the secret to Singapore’s success is that their housing projects are carefully designed to support mixed-incomes, beautiful green spaces, and access to high-quality public transportation that conveniently links residents to education and community centers. And last but not least, couple all that with the famous Singapore hawker centers (food courts) where all income classes and ethnicities meet, socialize, and dine on Singapore’s famously delicious and affordable cuisine.”
Wouldn’t it be interesting to find how children would plan their cities? No, this is not the lego building kind of exercise but something closer to actual planning exercises where children not only act as planners but stakeholders themselves. We always say they are the future and that know that they will inherit whatever good or bad we are doing now, and yet they have little say in that future. Perhaps we should heed what they think our cities require?

I am always amused about discussions and posts about transport and traffic where people appear to isolate the traffic as what needs to be solved, and where people criticize the latter and state that it is a transport and not a traffic problem. Both do not have the complete picture if that is what we want to start with. Land use, land development and the choices people make based on various other factors (including preferences) are among the other ingredients of the proverbial soup or dish that need to be included in the discussion. Remember land use and transport interaction? That’s very essential in understanding the big picture (macro) before even going into the details at the micro level. Why are there many car users or those who prefer to use private modes over public transport modes? Why do people prefer motorized over non-motorized modes? Maybe because people live far from their workplaces and schools? Why is that? Maybe because of housing affordability and other factors influencing choices or preferences?
Here’s a nice recent article on housing and transportation to enrich the discourse on this topic:
