On understanding road diets
I’ve written and shared articles on road diets and complete streets before. Here is another article share on road diets
Johnson, R. (April 21, 2025) “Explainer: What is a Road Diet – And Why Should Cities Embrace It?,” Momentum Magazine, https://momentummag.com/explainer-what-is-a-road-diet-and-why-should-cities-embrace-it/ [Last accessed: 22/04/2025]
To quote from the article:
“The road diet isn’t about punishing drivers. It’s about creating streets that work better for everyone—from the parent pushing a stroller to the teenager biking to school, the delivery driver navigating a tight urban corridor, or the senior walking to the store.
As our cities continue to evolve, road diets offer a cost-effective, data-backed, and scalable way to make them safer, cleaner, and more livable. It’s not just about losing a lane—it’s about gaining a better future for urban mobility.”
Indeed, the first thing that usually comes to mind of motorists whenever road diets and complete streets are mentioned is that the road space (and consequently capacity) will be reduced. This reduction of capacity is actually from the perspective of the motor vehicle rather than the number of people traveling along a road as well as improving road safety for all. The article is spot on in its discussion on the resistance to road diets (and complete streets). Of course, context is very important here and it is important to identify which roads can be transformed for the transformation to be most effective.

Article share: What’s Incomplete About Complete Streets?
The concept of road diets circulated in Metro Manila more than a decade ago. I recall the Metro Manila Development Authority (MMDA) picked up the concept and attempted to apply it in some parts of Metro Manila. Since there are no evidence of that endeavor surviving now, then we can assume that it was a failure. There is no wonder there as I also recall the effort to be half-hearted and more to get media mileage (cheap talk or lip service) out of it. Road diets eventually evolved into the complete streets (though the literature now will state road diets as part of complete streets). That experience and similar initiatives of varying success (or failure) rates are not unique to the Metro Manila but is actually happening elsewhere including cities in countries where the complete streets have been applied more comprehensively and yet somehow found to be lacking or not as effective a solution as expected. I am sharing an article here that discusses what seems to be lacking or ‘incomplete’ as it is referred to.

Quoting from the article:
“What’s missing? First of all, even the best Complete Streets policy can’t solve the problem of fiscal scarcity. Even in a city committed to Complete Streets, street redesign must fight for public dollars with other worthy goals such as education and public safety. As a result, Indianapolis’s improvements are a drop in the bucket. The city maintains 3,400 miles of streets and roads, so its 100 miles of bike lanes affect only 3 percent of the city. Similarly, 2,000 miles of the city’s roads still lack sidewalks.
Second, the quantitative benchmarks seem to focus on sidewalks and bike lanes (Sec. 431-806), and the policy doesn’t mention traffic calming or similar policies. So if the city had a six-lane road with traffic going 60 miles per hour, the Complete Streets policy would not affect that road except to the extent necessary to build a sidewalk or a bike lane.** Thus, even the best Complete Streets policies don’t really address some of the most dangerous features of American street design.”

The Ortigas Center bike lanes, complete streets and road diets
The MMDA recently stated they were planning to apply the road diet concept to EDSA by narrowing the current lane widths in order to add one lane per direction. While the idea seems to of good intention, the mention and application of road diet is flawed. I have previously shared an article on social media showing the definition and examples of complete streets:
Clearly, complete streets are for the benefit of everyone (i.e., inclusive) and not biased for motor vehicles. Here is a photo of F. Ortigas Ave. at the Ortigas Center in Pasig City showing the correct application of the Complete Streets and Road Diet concepts to an urban street. Note the elements for cycling and walking that are very prominent in the re-design of the street.
Protected bike lanes at either side of F. Ortigas Ave. at the Ortigas Center
We hope to see more of these re-designs in many other cities and towns in the Philippines. It is not a really difficult concept to apply or adopt as technically these are not complicated. However, there needs to be a change in the mindset of planners and engineers when they do these exercises considering how car-oriented our designs are. It is easy to say we want more people-oriented transportation facilities until it dawns on us how dependent we are on cars and resist the efforts to realise more sustainable designs.

On the opposition to “complete streets”
I recently read an article about the opposition to road diets in California, USA:
Tinoco, M. (2018) “How to Kill a Bike Lane”, http://www.citylab.com, https://www.citylab.com/transportation/2018/05/how-to-kill-a-bike-lane/559934/?utm_source=SFTwitter [Last accessed: 5/20/2018]
So far, we know that at least three cities are progressive enough to implement road diets including Marikina City, Pasig City and Quezon City. Iloilo doesn’t count yet since their bike lane was constructed along the very wide Diversion Road. Our recommendations for Tacloban, if implemented by the city, will probably result in the second most comprehensive application of road diets/complete streets in the Philippines after Marikina, which implemented their bikeways network almost 2 decades ago. There are sure to be many who would be opposed to such schemes as many still have the view that streets are for motor vehicles. This car-oriented thinking is something that will be a challenge to advocates of people-oriented transportation systems. Hopefully, many can learn from experiences here and abroad on how to reclaim space for people leading to safer and more inclusive transport for all.

Caught (up) in traffic
