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.

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?

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, 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?
- 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.

Worn down shoes
I got a pair of shoes from a shop/brand I don’t usually buy shoes from last April and used them almost daily for my morning walks. Here are photos showing the conditions now.
The bottoms are pretty worn out. I am careful during my walks as I may slip on some surfaces as the soles lose traction.
There are tears to the fabric of the upper part of the shoe where it’s connected to the soles. This is on the right shoe.
This is the tear on the left shoe.
I was hoping these would be as durable as my other shoes that I have used for my walks. Unfortunately, they are what they are as of now. I can and still use them almost everyday but am wary about their not being usable in the near future.

On the increase in road crashes involving trucks in Rizal province
The incidence of road crashes involving trucks in our area and along my regular commuting routes seem to be increasing. Many of these are large, heavy trucks often with cement or other construction materials being hauled from one of the quarries or plants located in Antipolo and neighboring towns.
Road crash near Tikling Junction last Saturday, July 5, 2025
The resulting congestion due to the partial blockage of Ortigas Avenue Extension had eastbound traffic backed up almost up to Cainta Junction and it took more than an hour to pass the site before going up to Antipolo. Why are these crashes becoming more frequent? Perhaps these trucks are not well-maintained in the first place. Another issue is perhaps truck overloading. Whatever the issues may be whether we can isolate one or its a combination of several, interventions must be formulated and implemented. The LGUs need to be more proactive about this and not be over-reliant on the police who are there usually after a crash has occurred, and too late to prevent damage to property, injuries or worse, fatalities.

E-trikes in Naga City
Just like other cities in the Philippines, Naga City now has electric tricycles operating and providing transport services. These are welcome developments for many cities and municipalities as these trikes are low emission and low noise vehicles. They also basically have higher passenger capacities compared to the conventional trikes though service characteristics may not be so different from the conventional trikes. For example, ‘special’ rides mean fewer passengers.

E-trikes queued at the station
Despite the popularity, there are still many questions regarding e-trikes. These include durability, battery life and profitability. With the proliferation of e-trikes and their various models, these issues hope to be resolved in the next few years as more evidence relating to these and other issues come out.

Transport options between Naga and Legazpi
I wrote about the PNR still operating between Naga and Legazpi cities. However, there is only one roundtrip per day and that is the Legazpi-Naga-Legazpi trip. If you want to do the Naga-Legazpi-Naga trip, you have to spend at least the night in Legazpi. But the latter schedule is not so good for the return to Naga as the train leaves Legazpi at 4:30 AM! Aside from the rail option, most people will use road-based transport. That is, most people will probably take a bus or van. There are many bus companies and UV Express vans operating along the corridor (Pan Philippine Highway) connecting the major cities and municipalities of the Bicol Region.
We saw this van parked along the roadside as we were waiting for our turn to proceed along a section under construction employing a alternating one way traffic scheme.
A close-up showing the UV Express van’s end points to be Naga and Legazpi. The declared passenger capacity is 23. Though this appears to be a long or stretched van, I can only imagine how comfortable or uncomfortable it is to ride these for 3 plus hours one way.
More on Bicol transportation in my posts this coming July!

PNR services from Naga City
I have yet to share the photos I took at the PNR Station in Naga City. Instead, I am sharing here the current train schedule and fares.
There are only three trips from Naga to Sipocot – two in the morning and one in the afternoon. Meanwhile, there is only one trip to Legazpi. Sipocot is in the same province, Camarines Sur, while Legazpi is the capital of Albay.
Fare rates between Naga City and Legazpi City. There are 15 stops along this route.
Fares for destinations between Naga and Sipocot
Timetable between Naga and Sipocot. It takes 1 hour and 12 minutes one way. It seems I wasn’t able to take a photo of the Naga-Legazpi timetable but the staff told us it takes 3 hours to get to Legazpi.
The station staff also told us that the train from Legazpi leaves at 4:30 AM. If it also takes 3 hours, then it arrives in Naga at 7:30AM. This can be okay for a super-commuter even at this travel time and speed (about 33 km/h). The frequency of trips between Naga and Legazpi should increase and will probably do once the PNR completes rehabilitation of what was termed as the Main Line South.

Electric taxis anyone?
Finally saw one of the taxis operated by Green GSM, which is a Vietnamese company. This is supposed to be the first all-electric taxi service in the Philippines.
My colleagues and I were talking about this. Among other topics is whether these taxis will not encounter problems once the rains pour and many streets are flooded. We also wondered whether these vehicles will add to the congestion; slugging it out with the established competitors.
Another, more deeper and serious topic is whether these are really clean. While these are emission free as far as the proverbial tailpipe is concerned, the sources of power are not necessarily so.
While we do have renewables in the mix including hydro, geothermal, solar and wind, much of our power used to produce electricity uses fossil fuels.

Aerial photos – reclamation projects in Manila Bay
Last week’s travel allowed me to take aerial photos of the reclamation projects in Manila Bay. Here are the photos:
The view as we lifted off from NAIA shows SM’s reclamation project across from the MOA complex.
Our plane then climbed and afforded this close-up of sorts of the reclamation across from the now closed Sofitel Hotel.
Past the largest of the three reclaimed lands is another man-made island.
As our plane turned left, we were able to see all three reclamation projects
A close-up of the reclamation across the MOA complex. Also in the photo is NAIA.
All three reclamations in one photo as we continued to turn towards the south and southeast (towards Bicol).
More aerial photos soon!
