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.

Article share: on improving road safety in the midst of automobile dependency and sprawl
I am sharing another very informative article on road safety. While it is written for North American cities, most concepts and principles presented are applicable elsewhere and especially in cities and municipalities that tend to model their development after America. Increasing dependence on private vehicles (not just automobiles but including motorized two and three-wheelers) have resulted in increasing incidence of road crashes and though we have limited space, we tend to develop land as if we can afford sprawl and its consequences. Here is the article:
Litman, T. (April 25, 2025) “End Human Sacrifices to the Demanding Gods of Automobile Dependency and Sprawl,” Planetizen, https://www.planetizen.com/blogs/134838-end-human-sacrifices-demanding-gods-automobile-dependency-and-sprawl?utm_source=Planetizen+Updates&utm_campaign=d3fcb4d16b-newswire_05_05_25&utm_medium=email&utm_term=0_-6cce27a957-89144212&mc_cid=d3fcb4d16b&mc_eid=9ccfe464b1 [Last accessed: 16/05/2025]
To quote from the article:
“North American transportation agencies currently apply various older strategies, which should not be ignored, but to achieve additional crash reductions they need new strategies, such as those listed in the following table. The older strategies are targeted programs applied after most major transportation and land use planning decisions are made. New strategies include structural reforms involving more multimodal transportation planning, more compact development, transportation demand management incentives and parking policy reforms. This recognizes that all types of planning decisions affect transportation safety, and that many policies can increase safety in addition to other economic, social and environmental benefits.
The new paradigm expands traffic safety strategies to include structural reforms that increase transport system diversity and efficiency. They tend to provide many economic, social and environmental benefits in addition to safety.”

Let’s act on road safety crisis!
May is Road Safety Month. It’s quite ironic that we started the month with some of the most gruesome crashes including one at SCTEX and another at NAIA. There is indeed a crisis on road safety but many are in denial or perhaps insensitive to the impacts of these crashes. We need to act and only together can we be most effective in reducing the risks for all road users.
So what can one do? How can one contribute to making roads safer? Sharing this poster from the Road Safety Research Laboratory (RSRL) of the National Center for Transportation Studies (NCTS) of the University of the Philippines:

On gruesome road crashes and how they are reported
The past days have been terrible in terms of road crashes that have been reported. Of particular interest is the one last week involving four vehicles – a provincial bus slamming into 2 passenger vehicles against a stopped truck, and crushing both vehicles and their occupants. This was along SCTEX as vehicles were approaching a toll plaza. The trucks and passenger vehicles were stopped in a queue when a bus slammed into them. As of now the reports state at least 10 have lost their lives. One child miraculously survived the crash but lost both parents as per reports.
While mainstream media seems to be still conservative in how they report these incidents, social media offers much graphic, unedited content. Last Thursday and Friday, friends have shared posts by different people who have videoed the aftermath. It was gruesome and I will not describe them here nor share those videos that also appeared in my Facebook as reels. While there is the shock effect to the shared videos, one wonders whether these ultimately contribute to improving road safety or just add to what is now regarded as another category of porn (you’ve probably heard or read about food porn, tourism porn, shopping porn and poverty porn). These now have become more like spectacles that are viewed more for (sick) entertainment rather than to move people to action to address the road safety issues we face. While there are many responses offering comfort or prayers, how many would really act and actively call for safer transportation? As one friend exclaims – “Where’s the rage?”

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:

Shared article on shared mobility
Here’s is a nice short read on a Sunday about shared mobility. The article is of particular interest to me because it tackles the needs of persons with disabilities, senior citizens and those in low income households.
Seruga, K. (April 14, 2025) “Shared mobility: Making travel easier for all,” Knowable Magazine, https://knowablemagazine.org/content/article/society/2025/increasing-access-to-shared-transportation [Last accessed: 27/04/2025]
“But if you’re disabled or elderly, living in a low-income area or — imagine! — without a smartphone or credit card, using these shared mobility services becomes a lot more difficult. They tend to cluster in more affluent urban areas, and are often inaccessible to people with reduced mobility or those traveling with young children needing child seats. In part because of these factors, users are disproportionately younger, wealthier, able-bodied, white and male.
Shared mobility could be a key part of a more sustainable transportation system. But to be most effective, it needs to include everyone. For-profit shared mobility providers have largely failed to deliver on this, but various initiatives and projects are finding creative solutions to reach underserved communities.
The potential benefits are large. On-demand shared mobility that feeds into well-developed public transportation systems could reduce the number of vehicles in some cities by 90 percent and cut transportation emissions by 50 percent — but only if it largely replaces private car use. “The car has to be a guest, not the main actor,” says Luis Martinez, lead modeler at the International Transport Forum, who coauthored a paper on shared mobility and sustainability in the 2024 Annual Review of Environment and Resources.”
There is a cautionary tale on ‘for-profit’ shared mobility here but a major difference in countries like the Philippines from those in western countries is the presence motorcycle taxis and the surge in the ownership of electric three-wheelers. These have changed the way people travel though their impacts are only now being assessed.

On reckless driving and riding, road rage, and kamotes
A story went viral a couple of weeks ago about a motorcycle rider getting shot by a driver. Many discussions and videos have been shared with some sympathetic to the driver and others to the riders. One thing is definite from the videos shared when you filter the commentaries and biased opinions – both the driver and the riders are guilty of reckless driving or riding. With all due respect to the root crop often invoked and associated with these kinds of motorists, kamotes as they are called seem to have increased no thanks to many of these learning to operate motor vehicles without being properly trained, oriented, evaluated and tested if they deserve having licenses. The increase and documentation of incidents of road rage should be taken very seriously by the LTO and serve as reference for improving the licensing system.
Here’s an informative material on reckless driving from the National Center for Transportation Studies’ Road Safety Research Laboratory:
This Holy Week, there are many who are using the roads whether for long distance travel (e.g., spending the holidays in their hometowns away from the metro) or for the typical religious trips (e.g., pilgrimages, Visita Iglesia, etc.). Motorists should exercise caution as they drive or ride. We should be more mindful of the impacts of our behavior to other travelers whom we share the roads with.
Safe travels to all!

On step counts towards health and wellness
I’m sharing here an article about step counts. I guess the jury is still out there so to speak when it comes to the number of steps per day. The key is really to be active rather than just sit or lie down for most of the day. And there are many ways to be active and be able to measure it so you can monitor your movement.
Loudin, A. (February 28, 2025) “Why step count remains the most impactful fitness stat,” WebMD, https://www.webmd.com/fitness-exercise/news/20250228/why-step-count-remains-most-impactful-fitness-stat [Last accessed: 4/14/2025]
To quote from the article:
“For decades, the goal was 10,000 steps a day — but further research has shown that step counts as low as 2,500 still deliver long-term health benefits that increase as your step count rises — even past 10,000. The bottom line, however, is that more movement is better for you and serves as the best measurement of longevity.”
You can walk to start your day. You can walk in the middle of the day (say lunch time). And you can walk after dinner. And that’s just walking. Of course, you prefer to jog, run or bike, even swim, then that should do it for you in terms of being active. Walking though is really for most people who are physically able. And you can do it outdoors or indoors (yes, even in a building). So that’s where you should start in terms being more active towards health and welnness.

On a different kind of transport – electric suitcases
Here’s an interesting article for Sunday. I guess you’ve probably seen these at airports and even malls?
Unseen Japan (February 3, 2025) “Japan Warns Against Use of Electric Suitcases ,” Medium.com, https://unseenjapan.medium.com/japan-warns-chinese-travelers-against-use-of-electric-suitcases-d3eb946f2980 [Last accessed: 2/23/2025]
To quote from the article:
“Electric suitcases act as miniature people-movers, preventing people from having to walk from point A to point B in sprawling locations like airports. With a speed of 10 to 13kph, they’ve proven especially popular among tourists from China.
They’re also somewhat dangerous. On top of the danger of running into other passengers, people can lose their balance and take nasty spills.
The devices have proven a nuisance outside of airports, too. Last year, police in Osaka charged a woman for riding an electric suitcase on a sidewalk. Riding the device violates Japan’s motor vehicle laws, as it’s not legally classified as an e-scooter. It also violates the law around motorized vehicles on the sidewalk, which are only allowed for certain devices that restrict their top speed to 6kph.”
While these “act as people-movers”, I don’t think these could be regarded as transport under the category of micromobilities. If these are allowed to proliferate, then these will create new problems and come into conflict with active transport. What do you think?

On unwanted traffic
I just want to end this first month of 2025 with a commentary on unwanted or undesirable traffic. Last year, one of our neighbors leased their property to a trucking company. This was without information to the homeowners’ association and certainly without the knowledge or notice to neighbors, particularly those near their property and along the routes the trucks use. The result was unwanted truck traffic along roads that we usually used for our daily walks. Truck drivers’s usually drove the vehicles as if they were not in a residential area. That is, they were usually fast and belching smoke. Add to this the drivers hanging around and even loitering around the village. Many neighbors complained about this but the resident did not respond favorably or in a neighborly manner. And so each one of us had to confront the drivers ourselves and reminded them to drive carefully and slowly as they were in a residential subdivision. The village security was also told about them and the roving guards also reminded the drivers about safe driving.
And so I was pleasantly surprised when during my first walk of the year, I found that there were no more trucks along the road and parked in their property. I thought this was a nice New Year’s gift and ended what is generally regarded as an external cost to society.
The now clear street in our neighborhood used to be lined with trucks. This street was quite busy, noisy and smelled of emissions from idling trucks. It’s good to recover the road space for walking again. Do you have something similar happen in your neighborhood?

Caught (up) in traffic
