On defining the 15-minute city

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”).

Are roads really designed just for cars?

The answer is no. Roads were and are built as basic infrastructure for transport no matter what the mode. However, the standards for dimensions (i.e., number of lanes, widths, etc.) are based on the motor vehicle capacity, and structural standards (i.e., thickness, strength, reinforcement, etc.) are based on the weights they are supposed to carry over their economic lives. The pavement load as it is referred to is usually based on the cumulative heavy vehicle traffic converted in terms of the equivalent standard or single axles or ESA. An ESA is 18,000 pounds or 18 kips in the English system of measurements or 8.2 metric tons in the Metric system.

A typical local road – is it really just for cars or is it also for walking and cycling? Or perhaps animal drawn transport? 

A colleague says many of the posts in social media pitting bicycles with cars are already quite OA (overacting). I tend to agree as I read how people generalize roads being car-centric. Roads have been built basically to serve a avenues for transportation. They were improved over time in order to have more efficient ways to travel by land. It didn’t hurt that vehicle technology also developed over time and bicycles somehow became less popular than the cars and motorcycles. The motorcycle itself evolved from bicycles so in a way, it is the evolved and mechanized form of the two-wheeler.

In a perfect world, people would be sharing the road space and it would be equitable among different users. In a perfect world perhaps, it won’t be car-centric as there would probably be better public transport options and transit will be efficient, reliable, comfortable and convenient to use.

The reality, however, is that we do not live in a perfect world and transformations like the ones being pitched on social media are nice but are also not as inclusive and equitable as their advocates claim them to be. I’ve always said and written that you cannot simply change transportation without also implementing changes in land use and housing in particular.

Why do we need wide roads connecting suburbs and urban areas? Why is there sprawl? Why do people live in the periphery of CBDs or the metropolis? It is not just about transport though it seems easier to focus on this. Even transportation in Japan, with Metropolitan Tokyo and its equivalent of NCR plus as a subject, needs to be properly contextualized for land use and transport interaction and development. It seems that even with a comprehensive and efficient railway network, there are still shortcomings here and there. We don’t have such a railway network (yet) so we need to find ways for easing the currently long and painful commutes many people experience on a daily basis. That means continued dependence on road-based transport and trying to implement programs and schemes to improve operations.

On predicting how new developments will affect pedestrians

I’ve been involved in a number of traffic or transport impact assessment (TIA) projects in the past. In these assessments, not much is usually written about the impacts to pedestrians though we make sure that there is a section discussing their needs (e.g., sidewalks, crossings, footbridges). Unfortunately, even with specific recommendations, there is no assurance that the proponent will revise their designs. The typical TIA in the Philippines is undertaken after there have been architectural plans already prepared if not completed. By completed here, I mean they are practically final from the perspective of the client or proponent. The exception it seems is a big mall chain that seems to constantly revise their plans and for which our recommendations are almost always considered and incorporated in design.

I am sharing this recent article on the development of a new traffic model to predict the impacts of new developments on walkers.

Wilson, K. (April 26, 2021) “New Traffic Model Predicts How New Developments Will Affect Walkers,” StreetsBlog USA, https://usa.streetsblog.org/2021/04/26/new-traffic-model-predicts-how-changes-affect-walkers/ [Last accessed: 5/12/2021]

From the perspective of doing TIAs, I think that there should be a conscious effort of including the needs of pedestrians (walkers) and cyclists in impact assessments. Too often, (and I too am guilty here), there is but a minor mention of their needs and recommendations can be disregarded by both proponents (e.g., little or no change in designs to accommodate pedestrian requirements) and the local government (i.e., no push to make sure pedestrian needs are addressed).

On the tech side, there is a local development that can be used for counting pedestrians and cyclists. The TITAN project funded by the DOST-PCIEERD developed a tool that can count pedestrians and cyclists in aid of studies involving them. Such tools can be useful for data collection regardless of whether there is a new project or a TIA being undertaken.

On building the ideal city from a transportation perspective

There’s a not so old article that popped in my timeline of articles I’ve read the past years. I thought I would make a quick share of it here. It is a good read and something that will never be irrelevant for as long as we have not redeveloped our cities and municipalities for transport equity and sustainability. Here’s a takeaway from the article:

“The ideal city is a place where lots of different kinds of people with lots of different amounts of money can live and work. It has to be easy to get around without a car, even for people whose bodies can’t ride bikes or hop over potholes, and for people who have kids to drop off on the way to work and groceries to buy on the way home, and maybe flowers to buy next door to the dry cleaner’s. These are places where people want to live, because it’s nice there. The fact that those places also adapt to and mitigate climate change instead of causing it is a bonus.”

Here’s the article from last year:

On how communities should be?

This post is related to my recent post about Philippine cities and municipalities already somehow being 15-minute units. I am sharing another article I’ve read and reread for its current relevance.

Litman, T. (March 15, 2021) “A Complete Community is All Mixed-up,” Planetizen, https://www.planetizen.com/node/112565?utm_source=newswire&utm_medium=email&utm_campaign=news-03222021&mc_cid=628c8ee4b1&mc_eid=9ccfe464b1 [Last accessed:

The article is loaded with references that you can download and use in research or practice. And there are these two tables – Walk Score Ratings and Public Amenities – that are quick guides or references to what is desired to be achieved in communities.

Enjoy!

On the importance of trees along streets

I’ve written before about the importance of having parks around a city or town. Here’s an article I recently read about the positive impacts of trees along streets:

Stimpson, A. (March 12, 2021) “Green health: a tree-filled street can positively influence depression, study finds,” The Guardian, https://www.theguardian.com/us-news/2021/mar/12/baltimore-study-trees-mental-health-study [Last accessed: 3/29/2021]

Tree-lined street somewhere in Antipolo City, Rizal

We often refer to cities as the urban jungle. Why not really, literally make cities as urban jungles by planting more trees and other plants where its possible to grow and nurture them. Gardens may be grown not just for flowers or aesthetics but for food. Perhaps architecture should deliberately be oriented for greens? Orchard Road in Singapore is much admired for its trees. Surely, similar streets in our country can be landscaped accordingly.

On a different view of the ’15-minute city’ concept

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…

 

Lessons on housing we need to talk about

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.”

On planning our cities from a child’s perspective

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?

On housing and transport

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:
