After getting engrossed with EDSA, is Marcos Highway next?
If you monitored the news articles and social media post over the past two decades, there seems to be an obsession for EDSA. Circumferential Road 4 is the busiest corridor in Metro Manila, stretching across several jurisdictions including Caloocan, Quezon City, Mandaluyong, Makati and Pasay City. Aside from the MMDA, national agencies like the DPWH and DOTr have been heavily involved in traffic schemes and transportation infrastructure development along the corridor. These include variants of the travel demand management (TDM) scheme commonly called number coding. Since the 1990s, there’s the Line 3 and several overpasses/flyovers and underpass that have been constructed along major intersections (e.g., EDSA-Shaw, EDSA-Ortigas, EDSA-Kamuning, EDSA-Quezon Avenue, etc.). Nowadays, people are more into the EDSA carousel and most recently the pavement rehabilitation for EDSA. It seems we failed to realize that EDSA is just one corridor. There are others that also demand attention including those in other parts of the country.
Recently, a “carmaggedon” along Marcos Highway was in the headlines or shall I say was trending in social media. There was a lot of excitement for what has been a recurring nightmare to those residing along the corridor. I recall something worse occurred more than 15 years ago (pre-Ondoy), before social media and influencers and digital creators. At the time, Line 2 terminated at Santolan Station. And even back then, the MMDA insisted on playing with their U-turn scheme. I don’t recall a more in-depth study that could have involved micro-simulation modeling being done for the corridor. And since then, populations and traffic have grown steadily and as I’ve written about previously, the extension of Line 2 to Masinag seems to have had little impact on traffic. And so here we are with the MMDA still insisting on tweaking their U-turn schemes and relying mainly on gut-feel instead of a more scientific approach that may actually lead to more sound solutions for the corridor.
Approach to Marcos Highway from Felix Avenue – that’s the elevated Line 2 superstructure behind the Cainta arch.
Intersection of Marcos Highway, Felix Avenue and Gil Fernando Avenue – there’s a major foot bridge installed here so people can cross at the intersection, which used to be a signalized junction before the MMDA opted for U-turns for Marcos Highway sections under its jurisdiction.
Marcos Highway section fronting the Ayala Feliz Mall – the MMDA has played with the location of the U-turn slots in the vicinity of the Marcos Highway-Amang Rodriguez-J.P. Rizal intersection as they tried to determine the “optimum” locations of these slots.
Of course, there is also the case of Commonwealth Avenue. How many carmaggedons have occurred along that corridor? Isn’t it an everyday thing there? And there’s also Ortigas Avenue Extension and many other roads and streets where congestion seems to have been accepted as the norm. How do we make travel easier for most people? How do we improve commutes given the constraints and realities concerning behavior and choices?

Complicated intersections in Rizal – Tikling Junction
There are several major intersections in Rizal Province. Among them are 3 junctions in Cainta, Taytay and Antipolo – Cainta Junction (Ortigas Ave Ext.-Felix Ave), Masinag Junction (Marcos Highway-Sumulong Highway), and Tikling or Kaytikling Junction. The first two are signalized intersections. The last one is supposed to be a roundabout. All three are problematic in various ways and have been associated with congestion along the major roads intersecting at these junctions.
Tikling is quite interesting as traffic seems to have worsened after it was set up as a roundabout. Taytay enforcers have been deployed here but they seem to contribute more to worsening congestion rather than easing it. Motorists familiar with the area will tell you that traffic is better when there are no enforcers. Unfortunately, not all motorists here are from the area or are familiar with the rules for navigating or positioning at a roundabout. And so the intersection is often constricted with vehicles whose drivers and riders don’t practice courtesy.
Perhaps a combination of geometric improvements and more clever enforcement/management can improve intersection performance?

Vehicle refuge during floods
Passing Felix Avenue one early morning this week, I saw familiar scene. There were lots of vehicles parked along Felix Avenue (formerly Imelda Avenue) including the service roads along either side of this major road connecting Marcos Highway and Ortigas Avenue Extension.
These vehicles are owned by residents of subdivisions along the avenue whose areas are prone to flooding. These include Vista Verde, Metroville, Kasibulan, Karangalan and the two Green Parks. I didn’t see this along the stretch so the other flood prone villages like Village East and Country Homes. Perhaps they have been able to adapt better?
Car-centric discussions aside, when you go the ‘east’ you will notice a lot of people using SUVs. One reason probably is because many Rizal towns including Antipolo City, and Pasig and Marikina Cities are prone to flooding. Can you imagine over 50 years of flooding in these areas? And then with the current investigations concerning flood control projects, have you wondered if the ‘east’ really got their taxpayers’ money’s worth in terms of interventions?

Complex intersections in Davao City
My first project upon my return from Japan in 1999 was the Davao City Transportation and Traffic Management Plan Study. We found a few interesting intersections there. These included junctions with more than 4 legs. If all or most movements were allowed at these intersections, they would be most complicated and risky due to the number of conflicts. Of course, not all movements are allowed and many legs are one-way meaning there are fewer conflicts and less risky.
These intersections are large and while there are traffic signals, they were off when I was there.
Surprisingly, there was no congestion or near crashes. Either, traffic was light at the time (before 7AM) or motorists were driving at a level similar to Vietnam (where vehicles were like ants as they moved at intersections).
A bit of trivia here – 1999 to 2002 was the only period in a long time when a Duterte was not mayor of the city. This was the time the former president relinquished the mayoralty in favor of his Vice Mayor and was instead congressman representing the city. He immediately returned after one term rather than serve out 3 terms.

Pothole season
The heavy rains the past days have taken a toll on many roads. Special mention here would be city roads such as main arterials where traffic flow is affected by the pavement conditions. Here are a couple of photos of potholes along Katipunan Avenue.
The photos also reveal that cement concrete slabs are actually under the asphalt concrete. This means asphalt concrete was used more as an overlay to protect the cement concrete slab rather than as the main structural component that will carry the traffic loads. The pavement slabs may not necessarily be compromised but the hammering action of tires/wheels as they hit the potholes will definitely lead to more damage. The water, of course, is worrisome because once they seep or penetrate the cracks and interfaces between the slabs, they may compromise the layers beneath the slab. This will weaken the foundation of the pavement and lead to more critical damage. The challenge is how to repair these potholes when we are still experiencing heavy rains. Now that’s something the DPWH needs to figure out, learn and apply rather than the usual patch up work that results in mounds of asphalt replacing the potholes.

Rain and fog along Sumulong Highway
I just wanted to share a few photos of the conditions along Sumulong Highway these past days. With Felix Avenue and Ortigas Avenue Extension frequently flooded during this season, our commutes would usually be along Sumulong and Marcos Highways.
Despite the conditions of the road, there are still many who drive or ride recklessly. Speeding, weaving and cutting on slippery pavements increase the likelihood of crashes, which are preventable if only people will slow down and be more cautious.

Bollards along Marcos Highway
I noticed that there are new bollards installed along Marcos Highway and particularly along the curbs at either side of the road. These were installed only recently, perhaps last month, nut I only got a few photos the other day. Its not safe to take photos while one is driving so I asked the wife to take a few ones that I could use here and perhaps also in some of the lessons I teach.
These bollards are installed along the curb where a couple of fatal crashes occurred in the past months.
The bollards are probably there to help improve road safety. They are reflectorized to you can’t miss them at night. Immediately behind them though are concrete barriers so hitting these will definitely damage the vehicle with a possibility of serious injuries to the vehicle occupants if not fatalities. Could there be a safer design intervention here? Perhaps that curbside lane can be converted into a protected bicycle lane. The barrier and the bike lane itself will be a buffer zone between motor vehicle traffic and active transport including pedestrians.

On safe school zones
We’ve been working for safer roads since I started practicing as a transportation engineer/planner. Most recently, we were working on a program supported by UNICEF on Child Road Traffic Injury Prevention (CRTIP). The work towards safer roads especially for those who are most vulnerable is always challenging but it is something that is definitely worthwhile. As we approach May, which is Road Safety Month in the Philippines, I will try to write more about road safety.
Here is an infographic shared by the Road Safety Research Laboratory of the National Center for Transportation Studies of the University of the Philippines:

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.

Caught (up) in traffic
