Article share: On AI as a tool for urban planning
Here is a quick share of an article on AI and its application to urban planning. I haven’t written about artificial intelligence here except maybe mentioning it along the lines of intelligent transport systems (ITS). There were what were termed as Expert Systems but AI now (including its potentials) is much more than the expert systems developed in the past.
Sanchez, T. (June 20, 2025) “In Urban Planning, AI Prompting Could be the New Design Thinking,” Planetizen, https://www.planetizen.com/blogs/135418-urban-planning-ai-prompting-could-be-new-design-thinking [Last accessed: 7/17/2025]
To quote from the article:
“Working across disciplines is essential. Collaborating with architects, landscape architects, engineers, artists, and technologists brings in diverse perspectives that can help spark new ideas. AI integrates knowledge and techniques from each of these fields. Contributing to a culture where planners feel free to experiment, where trying something new is encouraged rather than being frowned upon, is key to real innovation. Whether engaging with colleagues or prompting an AI model, creativity thrives in conversation and collaboration…
Cities should be shaped by creative thinking, and today’s challenges demand more of it than ever. Planners are in a unique position to combine deep local knowledge with new technologies, such as AI, to imagine, design, plan, and implement. AI should be seen not as a shortcut, but it has incredible potential as a partner or assistant with encyclopedic knowledge that helps planners stretch their creativity even further. As Wright advises, planners should challenge themselves with constraints to spark creativity: For instance, “What would you do if you had to write an entire zoning ordinance with 10 rules or less to make a sustainable built environment?” Such exercises encourage us to set clearer goals and find better solutions.
By combining traditional tools with emerging technologies, planners can design places that are not only functional but also vibrant, equitable, and resilient.”
What do you think about AI and its applications to urban planning including transportation and traffic?

How the Built Environment Affects Your Mood
Here’s a nice read as we do our storm watch, and probably explains why when we reminisce about college or university as “the best years of our lives”.
Source: How the Built Environment Affects Your Mood
To quote from the article:
“It is not for nothing that older adults often regard college as “the best years of your life” because in some cases it truly is. College years serve as a gateway drug to all the amenities and benefits of urban-core living — until you graduate that is. Then you have to return to your parents’ suburban home (as many Americans do) and suddenly all the amenities you had disappear. Your newfound college friends might make up for the lack of a diverse built environment. Nope, they all have moved back to their sprawling neighborhoods too, probably dozens of miles if not hundreds of miles away from your town. You might get a new car to celebrate your graduation and your new 9 to 5 corporate job. Work will keep you busy! But you know what else? Driving. No more waking up 10 minutes before class and arriving just on time. You might now have to wake up a few hours early to drive to your job through rush hour morning traffic, and do it all again in the afternoon.
You might also gain weight — not because you are eating more, but because you are walking less. Various studies demonstrate the link between car usage and obesity, showing “greater levels of obesity in communities where the private automobile is the dominant means of transportation.” And let’s not forget that obesity leads to other health issues such as diabetes and hypertension, among others. Mental health conditions such as depression are more prevalent in adults with obesity. Hence once college ends, graduates stop socializing, stop enjoying public amenities every day, start driving everywhere, stop walking and hence gain a little more weight in the process. Then it is no surprise that young graduates feel unfulfilled, and sometimes even depressed after college — for them, it feels they were robbed of an integral part of their new lives.
Our surroundings impact our mental and physical health. Living in neighborhoods with negative qualities can increase the risk of mental health conditions such as depression. At the same time, the pandemic made us appreciate diversity in our lives and what happens when we are deprived of it. Walkable cities are not “just a preference”; they develop happiness by fostering community trust, promoting physical activity, and offering nearby amenities. As learned, these spaces encourage healthy behaviors, reduce car dependency, and create opportunities for social interaction — all things that are crucial for our well-being.”
Based on this, no wonder I love to stay at the University of the Philippines campus in Diliman. I’m sure my colleagues in UP Los Banos feel similarly.

Designing a “Runnable” City
I’m sure you’ve read or heard about walkable cities. But have you read or heard about “runnable” ones? Here’s a quick share of an article about cities where you can run, jog or walk.
Source: Designing a “Runnable” City
To quote from the article:
“Several urban design principles can enhance the runnability of a city:
Connectivity and accessibility: This means developing a network of interconnected running paths and trails that are easily accessed from various parts of the city (especially neighborhoods). Even better if can be green corridors that connect to other parks and open spaces, and support continuous movement.
Safety and security: Ensuring running paths are well-lit and separated from vehicle traffic is crucial. Traffic calming measures such as vehicle lane narrowing, wider footpaths, and appropriate landscaping enhance runner safety. Street trees also help reduce car speeds, as they alter our perception of how wide the road is and provide a psychological cue that we’re in a residential area. Redesigning urban infrastructure to include dedicated running paths alongside walking paths and bicycle lanes, is a great idea.
Inclusive design: City design should encourage active mobility, which means including benches, water fountains, and restrooms along running routes. It means building footpaths that enables running, and avoiding uneven, slippery or unfavorable surfaces such as cobblestones. It also means making it easy to find your way around — even in unfamiliar environments.”

Planning for Accessibility: Proximity is More Important than Mobility
Here is a quick share of another very informative article that discusses the importance of proximity and more dense development in order to reduce car dependence.
Source: Planning for Accessibility: Proximity is More Important than Mobility
Here are some excerpts from the article:
“This shows that proximity is much more important than mobility in providing accessibility: location, location, location. For the last century, our transportation planning practices have contradicted this principle. Transportation agencies built urban highways that destroyed and degraded accessible and multimodal neighborhoods to benefit suburban motorists. This was racist and classist, but the mechanism was the way that transportation planners valued increased traffic speeds, measured as travel time savings, while ignoring the loss of accessibility imposed on urban neighborhood residents.
Of course, many other factors affect people’s transportation and neighborhood preferences. Some people need their cars for work or after-work activities, and not everybody can bicycle or use transit even if it is available. However, surveys such as the National Association of Realtor’s National Community Preference Survey indicate that many people would prefer living in more compact, walkable neighborhoods than they currently do but cannot due to a lack of supply.”
Such articles are a must read for those who want to understand why government needs to invest in land at or near the CBDs, and develop that land so people will not need to reside far from their workplaces and schools. Truly, there are many other factors affecting transport preferences or mode choice. Housing is one such factor that we continue to treat separately from transport. It is very (prohibitively) expensive to buy or rent in the city particularly in or near the CBDs. The result is people opting to purchase or rent homes in the suburbs. It doesn’t help that developers are also actively promoting subdivisions there and therefore are contributing to sprawl that puts so much pressure on transportation systems.

Opinion: The Arrogance of Social Media Urbanists
Here’s a quick share of an interesting article. It’s basically a reaction (I prefer not to call it a rant as the author refers to it.) and a fair one for those who are exasperated with the generalizations and criticisms often posted on social media that are thrown vs. planners. I would extend this observation about engineering as well. I suddenly remember discussing in one of my classes about how unreinforced concrete pavements are legit and not because a contractor or highway agency settled for inferior design or were corrupt that they decided not to use steel bars. It is very easy these days to post your opinion or criticism without understanding all the other (and probably essential) factors that come into play.
Source: Opinion: The Arrogance of Social Media Urbanists
Quoting from the article:
“What is the point of this rant, besides easing my frustration with my social media feed? It’s to hopefully educate those who think that changing close to a century of development patterns should happen overnight and that anyone who is not in lock-step agreement with the right way to develop is too ignorant to know better. No opinion has ever been changed by a snarky meme. Change happens through education, outreach, and time. Planners are not ‘afraid’ to build good things; they’re constrained by obsolete regulations and policies, deeply embedded political values, financial barriers, and the momentum of existing patterns of behavior. The goal should be to address those things and make it just as easy to build dense, mixed-use, walkable communities as it is currently to build single-use sprawl. If we get to that point, consumers will have equal access to the products they want, whether it be a single-family home on a cul-de-sac or a townhome with a coffee shop on the corner.
That is how we effect change. Arrogant and condescending posts on social media will not win converts to your cause, only harden their resistance.”

Cool Walkability Planning
I am sharing this article about planning and design for more walkable streets. The term ‘cool’ in the article refers to temperatures as people are less likely to walk if it is too hot to do so.
From the article:
“Improving walkability (including variants such as wheelchairs, hand carts, low-speed scooters) can provide significant benefits to people, businesses and communities, particularly in dense urban areas where land values are high and vehicle travel is costly. However, walking can be uncomfortable and unhealthy in hot climate cities, particularly those that often experience extreme temperatures (over 40° Celsius, 105° Fahrenheit). These conditions make walking unattractive and infeasible during many days…
A well-planned networks of shadeways (shaded sidewalks) and pedways (enclosed, climate-controlled walkways) incorporated into a compact urban village can provide convenient, comfortable and efficient non-auto access during extreme heat. They can create multimodal communities where residents, workers and visitors rely more on walking and public transit, reduce vehicle use, save on vehicle costs, and require less expensive road and parking infrastructure…
The main obstacle to comprehensive pedway development is the well-entrenched biases that favor motorized travel and undervalue non-motorized modes in transportation planning and investment. Transportation agencies have tools for planning and evaluating roadway improvements, and funding to implement them, but lack comparable tools and funding for walkability improvements such as shadeways and pedways, even if they are more cost effective and beneficial than roadway projects.”

On bicycles as a preferred mode of transport
Sharing this article on bicycles being the perfect mode of transportation. It is framed with respect to the concept of the 15-minute city. Here is the article:
Johnson, R. (April 19, 2023) “Embracing the 15-Minute City: 7 Reasons why Bicycles Are the Perfect Mode of Transportation,” Momentum Mag, https://momentummag.com/embracing-the-15-minute-city-7-reasons-why-bicycles-are-the-perfect-mode-of-transportation/ [Last accessed: 4/29/2023]
To quote from the article:
“Bicycles are aligned with the goals of sustainability and climate action, as they contribute to reducing greenhouse gas emissions, air pollution, and congestion. In a 15-Minute City, where the focus is on creating sustainable and climate-friendly communities, bicycles can be a powerful tool to achieve these objectives. By promoting cycling as a viable transportation option, cities can reduce their carbon footprint, mitigate climate change impacts, and promote a greener and healthier way of living.”

Video games for aspiring planners?
I saw this article on what are supposed to be the best video games for would-be or aspiring planners. To put this into the proper context, these are mostly newer games (or so I think considering certain games evolve over the years from the time they were first released).
Smith, A.N. (December 23, 2022) “These are the best video games for wannabe urban planners,” Bloomberg CityLab, https://www.bloomberg.com/news/articles/2022-12-23/these-are-the-best-city-builder-video-games-of-2022
When I was younger, the games to play were SimCity and Civilization. These have also evolved, and I think SimCity and Cities: Skylines (a game introduced to me by one of my students) might be the better ones for aspiring planners. You can test many concepts on these games such as transit oriented development (TOD), compact cities, etc. Of course, one can also play with actual planning and simulation software. If one has access to the transport model for Metro Manila, for example, you can test scenarios on this to see how the model will ‘react’ to various conditions or situations.

Another definition of the 15-minute city
We begin 2023 with an informative article defining the “15-minute city”. This is actually an entry in Planetizen’s Planopedia, which contains definitions of fundamental concepts in urban planning:
Ionescu, D. (December 2022) “What is a 15-minute City?” Planetizen, https://www.planetizen.com/definition/15-minute-city?utm_source=newswire&utm_medium=email&utm_campaign=news-12292022&mc_cid=ee083e2ee7&mc_eid=9ccfe464b1 [Last accessed: 1/1/2023]
I’ve written and shared articles about this concept before. Here are a couple from 2021 where I offered my opinions about the concept as already applied in the Philippines:

On guerilla tactics in urbanism – guerilla crosswalks
I am sharing this article on guerilla crosswalks in the US. It is interesting as communities or groups concerned with road safety decided to put up interventions (in this case crosswalks) in order to address safety concerns pertaining to pedestrian ROW along roads. In most if not all countries, pedestrians are limited where they may cross and there are jaywalking laws and penalties that are now being regarded as car-centric policies that need to be revised to favor pedestrians more than motor vehicles.
Zipper, D. (December 1, 2022) “The Case for Guerrilla Crosswalks,” Bloomberg CityLab, https://www.bloomberg.com/news/articles/2022-12-01/when-crosswalks-go-rogue [Last accessed: 12/10/2022]
To quote from the article:
“Such acts of unsanctioned “tactical urbanism” are of a kin to many other DIY street interventions, such as pop-up bike lanes. But they are not without risks. Affluent communities could have more residents willing to volunteer time and resources, for example, even though pedestrian deaths are concentrated in low-income neighborhoods. “The locations identified by guerrilla crosswalk activists may or may not coincide with where the planners and engineers have identified as highest need,” said Sam Zimbabwe, the former director of Seattle DOT.
But in Los Angeles, the Crosswalk Collective spokesperson said that the group is “always mindful of who has access to safety installations and who doesn’t,” adding that all its crosswalks to date have been sited in low- and moderate-income neighborhoods of Central and East Los Angeles.
Zimbabwe also noted the limited benefits of paint on faster roads (which the Federal Highway Administration has documented): “Particularly on multilane arterials, only marking a crosswalk without deploying other tools does not address the ‘multiple threat’ problem, where one driver stops but the driver in another lane does not.“ (The Crosswalk Collective spokesperson agreed, saying that the group rejects proposed locations due to safety concerns “all the time.”)
But in the right setting, unauthorized street infrastructure additions can lead to one of two outcomes — and both are constructive. One possibility is that the city removes it, in which case media attention and resident backlash put pressure on local officials to be more responsive to safety requests. (That coverage may also compel more residents to join street safety groups).
The other option is that city officials take the hint and accept what residents have built. Eight years ago, Seattle transportation planner Dongho Chang won the enduring appreciation of local cyclists when he responded to a pop-up bike lane first by thanking activists for their passion, and then by making the bike lane permanent. Now working with the Washington State Department of Transportation, Chang does not share Seattle DOT’s rigid opposition to guerrilla crosswalks. “It would be good to acknowledge the effort that was done by the residents,” he said. “If there is a way to keep the crosswalk, it would be ideal to try to do that.”“

This is, of course, in the US where such tactical urbanism might be in vogue in certain cities and communities. Would such be allowed or encouraged in the Philippines? Actually, there are already many cases where tactical urbanism has been applied and usually at the community or barangay level. Prior to the DPWH putting in rumble strips at the approaches of schools, junctions and other locations perceived to be accident or crash prone, people have devised ways to slow down traffic in favor of pedestrian crossings. These include laying down old rubber tires cut and stretched to become humps. There are also barriers laid out to form something like an obstacle course; forcing vehicles to zig-zag instead of going straight along critical sections. These have allowed schoolchildren to cross safe in school zones and pedestrians crossing safely at intersections.

Caught (up) in traffic
