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?

Traffic congestion along EDSA
I’ve taken some photos of EDSA traffic as well as the EDSA Carousel buses. Here are the more recent EDSA photos I took as I traveled from Makati to Quezon City after serving as a panelist in the Energy Transitions Dialogue last Wednesday.
I took this photo as we passed Guadalupe. I like this in the sense that it shows the clear ROW for the EDSA Carousel buses. One wonders why most of these motorists would prefer to drive their vehicles rather than take the bus or the MRT.
You can see in the photo that EDSA’s northbound side is clogged as far as the eye could see. If you check the image under the MRT bridge, it shows the southbound side was also congested. These photos were taken around 4 PM so this was still an hour before most people would be going home from work.
I mentioned in my comments at the panel that one consequence of giving number coding exemption to electric and hybrid vehicles is that this further diminishes the effectiveness (is it still effective?) of the MMDA’s number coding scheme. I don’t have the stats of how many EV’s and hybrids are registered and running in Metro Manila. Those numbers combined with actual counts will tell us how they are impacting traffic. That would be a nice topic for a paper. 🙂
The photos pretty much describe the transport situation in Metro Manila. Many of our major cities will be heading this way unless they improve their public transportation fast. If they do, then public transport mode share will be sustained if not increased. Metro Manila’s is already being eroded by inefficient public transport, motorcycles (including taxis) and perhaps unintentionally, electric and hybrid vehicles.

Flash floods in Quezon City
The rains poured again this afternoon and it was quite intense for more than an hour in Quezon City. We had floods at the UP campus and along Katipunan Avenue. Reports from various sources stated that there were also floods along EDSA and other major roads in the city. The floods come at a time when QC flagged flood control projects undertaken by the DPWH without the city’s blessings.
The flash floods were probably proof of the shoddy work associated with DPWH and its contractors. While QC residents and the LGU should share the blame for these, the scale and frequency of the floods indicate drainage issues.
The floods have led to intense traffic congestion and commuters being stranded due to public transport vehicles not being able to turn around. The latter is one of the cases where public transport appears to be lacking. Their numbers may not be lacking at all but the traffic conditions prevent their turnaround to address the demand for transport.

Examples of congestion pricing as applied in major cities
Here is a quick share of an article on cities that have been successful with congestion pricing:
Zukowski, D. (August 8, 2025) “5 cities with congestion pricing,” Smart Cities Dive, https://www.smartcitiesdive.com/news/5-cities-with-congestion-pricing/756987/ [Last accessed: 8/15/2025]
Quoting from the article:
“As cities around the world continue to see increased traffic delays, some have implemented congestion pricing programs to ease gridlock. Congestion pricing acts as a market-based mechanism: increasing the cost to drive in certain areas may encourage drivers to take alternate means of transport or travel at different times. Toll revenues can go to improving roadways and public transit or reducing other vehicle-related taxes.”
Indeed congestion pricing has been around and yet few cities have actually implemented congestion pricing schemes and have had success with it. In the Philippines, the discussions are basically on and off or intermittent. I recall there were already mention of congestion pricing in Metro Manila transport studies back in the 1970s but nothing really came out of those. Fast forward to the present and Baguio City in the northern Philippines implemented their version of number coding, which was supposedly a prelude to some form of congestion pricing but apparently is more of a travel demand management (TDM) scheme along the lines of Metro Manila’s UVVRP. Will we have our own proof of concept sometime soon even for a smaller area or district in any Philippine city? That will also be dependent on whether our so-called leaders can engage their constituents in meaningful discussions on the benefits of congestion pricing.

On the need to rethink traffic metrics
While Level of Service (LOS) criteria is a concept that can be applied to many other transportation facilities and aspects, Â among the LOS criteria that have been the subject of much criticism (and perhaps rightfully so especially in the context of safety) are the ones used for intersections. These are associated with delay reduction, which always favors vehicular throughput. The latter means basically, high LOS corresponds to prioritizing car (or motor vehicle) movement while not particularly taking into consideration the safety and movement needs of other road users (not using motor vehicles). Here is an interesting article on this matter:
Boenau, A. (July 9, 2025) “The old traffic math that keeps destroying neighborhoods,” Fast Company, https://www.fastcompany.com/91362348/road-design-traffic-math-destroying-neighborhoods-los [Last accessed: 7/15/2025]
Quoting from the article:
Here are three important questions for experts to ponder:
- Is slow-moving car traffic ever safer than fast-moving traffic?Â
- Do we have any obligation to provide safe and convenient access for people when they aren’t inside cars?
- What are the economic downsides of wider, faster streets in the central business district?
When planners and engineers truly wrestle with those questions, they can choose to remain a conformist who ignores the damage of traffic metrics, or become an outlier in the industry and make a positive impact that might be felt for generations to come. Things can get better in the end.

Again, I must say that rethinking roads and streets should be context sensitive. Still, safety should be the top concern especially for areas that is predominantly residential and/or school. Safety, after all, comes first in the definitions of transportation and traffic engineering.

Here comes the rain again…
And just like that, Habagat is here and dumping rains upon us again. Yesterday’s downpour during the early afternoon resulted in flash floods including a few along our route home.
The combination of heavy rains and floods have significant impacts on transportation as traffic slows down or even stops as roads become impassable. As most commuters are dependent on road based transport, this means a tremendous inconvenience to a lot of people.
I’ve also written about this topic before. Despite the implementation of various flood control and drainage improvement projects, we seem to be back to square one once the rains come. There is certainly something wrong that the floods are still here after spending so much to mitigate them.

Quick comments on the NCAP
The No Contact Apprehension Policy (NCAP) is finally being implemented in Metro Manila. The results so far has been dramatic in terms of the number of violations recorded and the images being shared so far about how motorists are behaving. Below is one of those photos being shared on social media to which I added some annotations. I will use this later to comment on the NCAP and how we can use the outcomes to assess the transportation situation and determine what interventions can be done. Some are already obvious from the photo – the lack of public transport options lead to people depending on private motor vehicles like cars and motorcycles for their commutes. MRT7 is yet to be operational and road public transport has not been rationalized.
More on this topic soon!

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.

Caught (up) in traffic
