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.

On transportation problems being treated like diseases
I am sharing this relatively old article on transportation problems needing treatments as if these were diseases. I say it’s ‘old’ because it’s from last year, and these days when much content is being pushed everywhere including mainstream and social media, things get old, quickly. Rewind to more than a decade ago and Intelligent Transportation Systems (ITS) wasn’t as popularly applied as today and Artificial Intelligence (AI) seems to be everywhere now including in transportation systems.
Menard, T. (September 1, 2024) “Transportation Rx: Treating Traffic Glut Like Doctors Treat Sinus Congestion,” Planetizen, https://www.planetizen.com/features/131478-transportation-rx-treating-traffic-glut-doctors-treat-sinus-congestion [Last accessed: 4/21/2025]
To quote from the article:
“Traffic congestion is not unlike congestion that builds up in the human airways. When we see a doctor, we are prescribed a treatment that clears the backup. Similarly for roads, rather than setting up road signs and cones to redirect traffic, cities can take a more prescribed treatment approach through methods such as congestion pricing and other road pricing strategies, as well as technologies like edge computing, navigation-enabled Mobility-as-a-Service (MaaS) modeling, and transit signal prioritization. “
This is not the first article to allude to medicine when the topic is traffic congestion. There are others that use terminology from the human body’s circulatory system. When an artery gets blocked, a bypass can be a solution. But perhaps we don’t need bypasses and look at other. more effective ways of dealing with transportation problems.

A new bottleneck along Marcos Highway in Antipolo City?
I’ve been wondering why there seems to be much congestion along the westbound side of Marcos Highway in the morning just before we reach SM Cherry. It is usually flowing there but the past weeks when we used the route instead of Sumulong Highway, traffic was really bad. As I am quite observant about the traffic and always looking for reasons or causes, I found that this was due to the alternative route Antipolo ‘opened’ that many motorists now take when traveling between Marikina and the side of Antipolo heading in the general direction of Cogeo.
The alternate route connects Marcos Highway and Sumulong Highway via TOCS Avenue (which intersects Marcos Highway near SM Cherry) and Sampaguita Street (which intersects Sumulong Highway past Masinag Junction and near the Hillside Centre Plaza before Soliven Avenue). If you’re coming from Marikina and heading in the direction of Cogeo or even Antipolo Simbahan then this route may provide shorter travel time as you won’t have to go around Masinag Junction to make an effective left turn to Marcos Highway (direct left turns at Masinag are not allowed).
This is the view from the queue approaching the intersection of TOCS Avenue with Marcos Highway from the eastbound side of the highway. Note that traffic is not flowing from the junction along the eastbound (Metro Manila bound) side of the highway.
A closer look with vehicles turning left to Marcos Highway from TOCS Avenue. There are usually Antipolo traffic enforcers facilitation (read: favoring) traffic from and to TOCS Avenue. This results to build-up along Marcos Highway where most traffic is through traffic.
The resulting congestion affects many travelers including freight along the westbound (Metro Manila-bound) direction of Marcos Highway.
While the alternate route likely provides shorter travel times for those coming from Marikina to Antipolo/Cogeo and vice versa, this is at the expense of more people and goods who and that travel along Marcos Highway. Antipolo should realize this even with basic observations on the traffic build-up in the area. Traffic for that alternate route should not be prioritized to the detriment of travelers along Marcos Highway.

Counterflow lanes in Bangkok, Thailand
I almost forgot again about this set of photos showing the implementation of a counterflow scheme along a long stretch of road in Bangkok. Heading out of Bangkok, I was able to take photos of the counterflow lanes and variable traffic signs used for this purpose. We were northbound meaning we were traveling outbound of the metropolis and opposed to the peak direction (southbound was inbound to Bangkok).
Approaching an overpass where variable traffic signs are installed overhead (i.e., on a gantry).
It is easy to see which lanes are assigned for our direction and which ones for the opposite flow.
On the overpass, you can see that the variable signs are installed at regular intervals. There are a few cones that act as physical separators (not really barriers) between opposing flows.
Sort of a close up of the variable signs and a cone. I assume the cones are placed there by traffic authorities. They might be transferred to the other side of the overpass if the counterflow was in favor of our direction.
Another photo showing the installed variable signs towards the other end of the overpass.
Four lanes are assigned to inbound traffic while only two are for outbound traffic.
At the foot of the overpass is a pedestrian overpass. The stairs appear to be quite steep based on the photo. I’m not aware of criticisms of the pedestrian footbridges in Bangkok. I would have to ask my Thai friends about their designs.
Another overpass where all lanes are assigned to the southbound direction
The parked vehicle on the chevron is with the traffic authority of Bangkok.
I actually started writing this in April last year. I will try to finish some drafts I started last year this month while also posting about my recent travel to Bicol.

To B(RT) or not to B(RT)?
I kind of expected questions or comments from my ‘students’ after my lecture last Wednesday about “Traffic Congestion.” Among my slides were those featuring solutions to transport and traffic problems. I presented both soft and hard approaches including travel demand management schemes and infrastructure that we should have built decades ago. The uniformed officers who were there had a very simple take on congestion – it’s basically because of a lack of discipline. While theirs may also be valid observations based on their experiences, ‘discipline’ is not the most critical problem that we have especially considering the ever increasing demand for travel. One government official present was very direct in his question about what I thought about the MMDA’s pronouncement that they plan to remove the EDSA Bus Carousel. I thought my reply and the following explanation was clear – it was a wrong move.
The EDSA Bus Carousel is simple. Bus lang sa bus lane (Only buses along the bus lane). Pag may private or pa-VIP, bawal at huli dapat (If there are private vehicles or those who regard themselves as VIPs using the lane, then they should be apprehended. An HOV (high occupancy vehicle) lane is more difficult to implement. Mas pahirapan ang pag monitor and enforce (It is very difficult to monitor and enforce). So this proposal to phase out the EDSA bus lanes don’t make sense from this perspective. In fact, I don’t agree with a couple of more senior transport experts who say that the MRT Line 3 is sufficient and that it hadn’t reached capacity yet. It has but in the time that the carousel has been operational, the carousel had absorbed much of the demand along the corridor. There is also the fact that it will take much time before Line 3 is upgraded. Are the new train sets here? Are the stations designed for these trains and more passengers? If the answers are no, then MRT3 will not have its capacity increased in such a short time. That also means the carousel is very much relevant not just to supplement MRT3 capacity but as a needed alternative mode for commuters.

Article on the evaluation of congestion pricing
I want to share this article on the congestion pricing zone in London. This is called the Ultra Low Emission Zone (ULEZ), which also met resistance when it was first implemented.
Selby, O. (January 16, 2025) “ULEZ expansion hasn’t hurt high street spending,” Centre for Cities, https://www.centreforcities.org/blog/ulez-expansion-hasnt-hurt-high-street-spending/ [Last accessed: 2/1/2025]
Quoting from the article:
“The benefits ULEZ has provided to public health have been studied extensively. The data is clear: London has the worst air quality of any UK city and the capital’s emission zone is helping to change this.
So far, card transaction data does not suggest that ULEZ is harming high street spend. This should reassure policy makers in London, who committed to the emission zone a while ago, and strengthen the convictions of policy makers in New York who are now following suit.”
The article is a nice reference not just for evaluation of similar congestion pricing schemes but can also be used for carless streets or zones. I wonder if there are similar work being done for Baguio’s congestion pricing scheme as well as the carless programs in Ortigas Center. Quezon City should also do this for the newly implemented program along Tomas Morato.

The journey to PHL’s railway renaissance
Here is a quick share of an article on railway development in the Philippines. It certainly took a while for railway development to get underway with considering rail transit would probably had a major impact on commuting particularly in Metro Manila and highly urbanized cities like Cebu and Davao that require mass transit systems to alleviate congestion.
Source: The journey to PHL’s railway renaissance
The article though doesn’t contain a narrative on the journey but rather only a summary of the rail projects that are currently being implemented as well as those in the pipeline. It would be a nice to have a more historical approach to this so-called journey so we can have an objective look at what happened to our railways from the 1970s when its decline began until the last few years when a so-called renaissance came to be.

Davao 8th, Manila 14th worst in Tomtom Traffic Index
I just want to share this news report here:
Source: Davao 8th, Manila 14th worst in Tomtom Traffic Index
I have to admit that I still have to figure out in detail how exactly their data were collected and evaluated. However, knowing and experiencing traffic in these cities, I would like to opine that traffic is still worse in Metro Manila cities compared to Davao and perhaps others across the country.
From 9-to-5 to Anytime: How Telecommuting Changes the Traffic Game
Here’s a quick share of an article on telecommuting:
Source: From 9-to-5 to Anytime: How Telecommuting Changes the Traffic Game
To quote from the article:
“As we look across these 83 cities, it’s clear that remote work has brought relief to some areas while leaving others just as crowded as before. The cities seeing the most benefit from WFH were those with a flexible, remote-friendly workforce and a supportive economic structure. For fast-growing cities, or those with heavy industry or logistics, WFH alone wasn’t enough to solve congestion.
Telecommuting has no doubt reshaped our roadways, but it’s clear that tackling urban congestion will require more than just a remote work policy. As cities continue to grow and evolve, the future of urban mobility will rely on creative solutions, from smarter infrastructure to updated transit options, to keep America’s cities moving in this new, work-from-anywhere world.”
There are lessons to be learned here for us in the Philippines. Telecommuting is not a new thing here especially considering we have many BPOs operating across the country. Indeed, it is not to be considered as the only solution but one of many we can use to reduce congestion and improve commutes in our towns and cities.

Are transportation issues election issues in the Philippines?
Are transportation issues in the Philippines? Or are these issues at the local level? Here is an article about how transportation issues were brought to light and were actual topics in the ballot in Los Angele, California in the US:
Tu, M. (November 25, 2024 ) “Bike, Bus and Pedestrian Improvements Won the Vote in L.A. How Did Advocates Pull It Off? “ Next City, https://nextcity.org/urbanist-news/bike-bus-pedestrian-improvements-healthy-streets-los-angeles-ballot?utm_source=Next+City+Newsletter&utm_campaign=532838ef65-DailyNL_2024_11_18_COPY_01&utm_medium=email&utm_term=0_fcee5bf7a0-532838ef65-44383929 [Last accessed: 11/26/2024]
The three lessons in the article are:
- Build a coalition – “In the lead-up to the election in March, Streets For All successfully secured endorsements from unions, climate organizations and business groups that saw the vision for safer streets.”
- Safety wins – “We could make climate arguments, we could make equity arguments, but the thing that felt the most bulletproof to us and the most empathetic to the general Angeleno was just road safety,”
- Keep it simple – “…simple messages were the most effective. Vredevoogd fought for one billboard on Vermont Avenue that read “In 2022, more pedestrians died on Vermont Avenue than in the state of Vermont.”
Los Angeles or LA as many people fondly call the city is well known for being car-centric (as opposed to San Francisco to the north, which is more transit-oriented). Perhaps we can learn from this experience though I know there are already groups and coalitions lobbying for better transportation in the Philippines. Are they successful and to what extent are they succeeding? Granted there are different situations and conditions, even modalities, to engage politicians, there are also so-called party list groups claiming to represent the transport sector but none appear to be really standing up for issues like improving public transport or road safety. And so the challenge is still there for people to make transportation issues election issues in the country.

Caught (up) in traffic
