On the fatal Katipunan road crash
The vehicles involved in a recent road crash that killed at least 4 people are still there and parked under the Aurora Flyover. A truck apparently lost its brakes and control and the driver ended up plowing into other motor vehicles, likely trying to gain some control in order to stop the truck. It was reported in news articles that there were 4 immediate fatalities and many suffered serious injuries. We probably won’t know the final fatality count unless someone reports on those hospitalized for injuries.
The crash highlighted again the need for vehicles, especially trucks, to be roadworthy. This time of year, most of these trucks run busy schedules with the logistics requirements. But maintenance is just one part of the problem here as the truck was reported to be speeding. So driver behavior is also a factor and apparently there was no monitoring (having those CCTVs don’t count if they are only used in a passive manner such as for evidence after a road crash had already occurred) or enforcement versus speeding for these large vehicles. Also, was the truck overloaded? This practice may also lead to the deterioration of the truck’s brakes and the vehicle’s mass contributes to the severity of the crash including the damage to other vehicles. The MMDA and LGUs have their work cut out for them to address these road safety concerns.

Campaign garbage
Politicians have used various media to further their personal interests and aspirations. Foremost perhaps of these interests and aspirations is getting elected. More effort it seems goes to promoting themselves however they can. While its months away from the campaign period, there are already a lot of campaigning going on with what I perceive as hard sells already having a head start when they shouldn’t be doing so at this time. You see the likes of Abalos, Marcoleta and Lee whose faces are scattered among buses, bills, billboards and tarps. And then there are the familiar names including re-electionists and relatives of incumbent or outgoing officials also ‘reminding’ people of their candidacies as if we owe them our votes.
Here is the case of this former mayor of Metro Manila City who is also a former cabinet secretary who is aspiring to become a senator. His campaign materials are on buses, billboards and posters around the country. Samahan daw nation sa Senado. Why? If he’s already doing something blatantly anomalous at this stage, I would not expect anything except more anomalies from him.
It is very frustrating that the Comelec is not doing anything vs. these premature campaigning, even stating that these are not illegal. Well, these definitely cost a lot of money. And how do you think these politicians will recover their ‘investments’?
I will post about these garbage in future posts. I just need to compile more examples to share here.

On bike lanes contributing to safer roads
Do bike lanes make roads safer? There are obviously mixed reaction to this question especially if you look as social media. If we are level headed about this topic and look at the evidence out there, the answer is yes. But there can be caveats as we try to contextualize in the local setting. The formal studies so far are in countries where the drivers arguably more disciplined than ours here in the Philippines. Driver behavior, after all, is a major factor for road traffic safety. Here is a good article for reference in the discussions and arguments for bike lanes:
Tu, Maylin (November 5, 2024) “How Bike Lanes Slow Drivers and Save Lives,” Next City, https://nextcity.org/urbanist-news/how-bike-lanes-slow-drivers-and-save-lives [Last accessed: 11/10/2024]
To quote from the article:
“Bike lanes with physical delineators (cones or bollards) were more effective than paint-only lanes at calming traffic, echoing a popular mantra for bike activists: “Paint is not protection.” (The lanes were not protected, however, because drivers could drive over the delineators.) For vehicles turning right, top speeds were reduced by 28% and average speeds by 21%. Paint-only bike lanes slowed driver speeds by up to 14% and drivers going straight slowed down by up to 8%…
The study adds that pop-up bike lanes are a cost-effective solution for studying the effects of more permanent solutions — after all, you could just borrow the traffic cones. A city could quickly implement pop-up or temporary infrastructure. Then, armed with data and community feedback, they could invest in making the changes permanent.”
The article also points to a technical paper or scientific article on the traffic calming effect of bike lanes. Here is the link to the article published in the Journal of Urban Mobility: https://doi.org/10.1016/j.urbmob.2024.100071

On whether bike lanes cause more traffic congestion
I previously share articles on whether bike lanes cause more traffic. This question has been asked so often as we have returned to the “old normal” levels of traffic and bike lanes that were put up during the pandemic have been neglected or removed in favor of motor vehicle traffic. The perception for those in-charge of traffic and transportation in local government units is that the space occupied by bike lanes take up the space demanded by motor vehicle use. Thus, the view that bike lanes cause congestion. Here is another article share in support of bike lanes:
Mortillaro, N. (October, 2024) “Do bike lanes really cause more traffic congestion? Here’s what the research says,” cbc.ca, https://www.cbc.ca/news/science/bike-lanes-impacts-1.7358319 [Last accessed: 01/11/2024]
To quote from the article:
“One would think that building more roads with more lanes for cars would reduce congestion, but research shows that’s not the case, thanks to something called induced demand. The more traffic lanes that are put in, the more it appeals to people who may not otherwise have chosen to drive, thereby putting more cars on the roads and increasing congestion.
“So for a short period of time, there might be a slightly improved [reduction], but within a year or two, or perhaps three, traffic is as bad or worse than it was before the lanes were added in the first place,” said David Beitel, data services lead at Eco-Counter, a Montreal company that collects and analyzes pedestrian and bicycle traffic data.
Conversely, if you put in more dedicated bike lanes, people tend to feel safer and demand for use increases, said Shoshanna Saxe, an associate professor at the University of Toronto’s department of civil and mineral engineering and Canada Research Chair in sustainable infrastructure.
“As soon as you build a bike lane, within a year, two years, the latent demand shows up,” she said.
Bike Share Toronto statistics show that ridership on its network of shared bikes has increased dramatically since 2015, when 665,000 bike trips were made annually. In 2023, that shot up to 5.7 million trips.”
I think many people here are already aware of the concept of induced demand. However, this is usually shrugged aside as realities in their situations (e.g., commuting options, locations of residences and workplaces, etc.) lead them to choosing private vehicles (i.e., cars and motorcycles) over public or active transport. The last paragraph there is significant though as there never was and so far a decent estimate of bike trips in any city in the Philippines. Granted that there are attempts to measure bike trips but the volumes published so far are not as reliable as we want them to be in order to be convincing decision-makers to put up more bike lanes. Of course, the convincing part is always challenging if decision-makers have already made up their minds in favor of the car.

On the need for helmet laws and their implementation to reduce fatal road crashes involving motorcycles
I found this article reporting on findings of their study on helmet laws and their impacts on road safety:
Insurance Institute for Highway Safety (October 20, 2024) Lax helmet laws have killed more than 20,000 motorcyclists, study shows, https://www.iihs.org/news/detail/lax-helmet-laws-have-killed-more-than-20-000-motorcyclists-study-shows [Last accessed: 10/23/2024]
To quote from the article:
“Wearing a helmet is one of the biggest things riders can do to protect themselves from death and traumatic brain injury,” said Eric Teoh, IIHS director of statistical services and the author of the paper. “We understand that requiring helmets for all riders everywhere would be unpopular with some motorcyclists, but this could save hundreds of lives each year. Those aren’t just numbers. They’re friends, parents and children.”
There’s a link to the study report in the article for those who want to have a copy of the report.

Sharing the road with persons with disabilities
The wife took this photo as we were turning at the roundabout at Tikling Junction in Taytay, Rizal. I just wanted to share this here for everyone’s awareness that there are those of us traveling who have certain disabilities that may not be so obvious. We probably see people on wheelchairs or special vehicles like those you’d find along Cainta roads especially near or in the vicinity of Tahanang Walang Hagdanan. And then there are those with PWD stickers on their motor vehicles. But are we aware and sensitive to the needs of others like this deaf cyclist? There should be policies to ensure their safety as they should be able to travel for whatever purpose they may have similar to our senior citizens and children who are among the most vulnerable road users. And drivers and riders should have the training and the empathy to share the road with them.
Deaf rider along Tikling Junction, Taytay, Rizal – not all would probably have a vest like this and motorists likely would be oblivious to their situation. There will also be pedestrians with similar circumstances who have natural disabilities. Irresponsible would those who are “deafened” by their gadgets like those wearing earphones or headphones while riding or walking. –
On congestion due to school drop-offs
I found this rather interesting article about congestion at school drop-offs in the US:
Hurley, K. (September 16, 2024) “How School Drop-Off Became a Nightmare,” The Atlantic, https://www.theatlantic.com/family/archive/2024/09/school-drop-off-cars-chaos/679869/?utm_source=copy-link&utm_medium=social&utm_campaign=share [Last accessed: 9/26/2024]
To quote from the article:
“Today, more parents in the United States drive kids to school than ever, making up more than 10 percent of rush-hour traffic. The result is mayhem that draws ire from many groups. For families, the long waits are at best a stressful time suck and at worst a work disruptor. Some city planners take the car line as proof of our failure to create the kind of people-centered neighborhoods families thrive in. Climate scientists might consider it a nitrogen-oxide-drenched environmental disaster. Scolds might rail at what they see as helicopter parents chaperoning their kids everywhere. Some pediatricians might point out the health threats: sedentary children breathing fumes or at risk of being hit by a car.”
The situation described in the article is actually already happening for quite a long time now in the Philippines and mostly at private schools. You have the same issues with the traffic congestion and road safety risks faced by schoolchildren in schools like Ateneo and LaSalle. The more ‘elite’ public schools like the science high schools may also have similar concerns. Can these be really addressed at the local level or is there a deeper, more complicated problem that needs to be tackled here (just to clarify that my questions are for our case here in the Philippines and not in the US)?

On transportation and global health – article share
I was supposed to write about the keynote lecture delivered during the 30th Annual Conference of the Transportation Science Society of the Philippines (TSSP). I am sharing instead an article written by Dr. Renzo Guinto who is an Associate Professor at the SingHealth Duke-NUS Global Health Institute based at the National University of Singapore.
Here is the link to his article on the Philippine Daily Inquirer: Health at the center of transport and mobility
I will not quote from the article and leave it to my readers to read and appreciate the articles content.

On ride hailing replacing more sustainable options for transport
We’ve long suspected that ride hailing or ride sharing is not as sustainable as their proponents and companies would project them to be. Here is more evidence showing how ride hailing has diminished other more sustainable transport options.
Kerlin, K. (August 28, 2024) “Half of Uber, Lyft Trips Replace More Sustainable Options,” UC Davis News, https://www.ucdavis.edu/news/half-uber-lyft-trips-replace-more-sustainable-options [Last accessed: 9/8/2024]
Quoting from the article:
“About 47% of the trips replaced a public transit, carpool, walking or cycling trip. An additional 5.8% of trips represented “induced travel,” meaning the person would not have made the trip were an Uber or Lyft unavailable. This suggests ride-hailing often tends to replace most sustainable transportation modes and leads to additional vehicle miles traveled. “
The article and the study by UC Davis is limited to their experiences with Uber and Lyft and perhaps others that employ cars. In our case, we have in addition motorcycle taxis or habal-habal that further takes away passengers from public and active transportation. Motorcycle taxis provide a very attractive alternative to conventional public transport modes as these are perceived to reduce travel times among other advantages they provide to users.
I will share some information later about the current mode shares in Metro Manila and how drastically public transport mode shares have been eroded post pandemic.

Caught (up) in traffic
