On walkable spaces for senior citizens
Here is a quick share of an article on walking and walkability, and the relation with dementia:
Steuteville, R. (March 10, 2025) “Living in a walkable place reduces dementia,” , https://www.cnu.org/publicsquare/2025/03/10/living-walkable-place-reduces-dementia [Last accessed: 3/29/2025]
To quote from the article:
“When we live in a walkable place, we move more, naturally. Unsurprisingly, exercise is linked to better cognitive health. Regular exercise increases memory, and boosts hippocampal volume by 2 percent.
Also, walkable neighborhoods are more stimulating. They are built on connected street networks, which give individuals more choices on how to get around and reward those choices with diverse physical paths linked to spatial memories. And they are mixed-use.
“Street layouts with better connectivity and walkability are associated with a reduced risk of cognitive impairment. Access to local amenities, such as food stores, community centers, and healthcare amenities, supports cognitive health,” the authors note.
Social connections also probably help. When you walk to a destination, you are more likely to have friendly interactions, which have been shown to reduce the risk of depression, and walkable places also boost the sense of community.”
As there are many senior citizens in our village, the topic is quite relevant. Most seniors probably won’t take a walk if they felt it was dangerous or risky even inside residential subdivisions. In our neighborhood, there are a few of them going around using their motorcycles or scooters. Most I see walking around perhaps for exercise or leisure rather than to go to a store or restaurant in the area. But increased traffic due to customers of restaurants that sprouted around the village has increased the risk for those who walk. Hopefully, the induced motor vehicle traffic generated by these establishments can be managed and regulated for the overall welfare of residents.

Old Versus New Traffic Safety Paradigms
Here is a quick share of an article on road safety:
Source: Old Versus New Traffic Safety Paradigms
To quote from the article:
“This issue is, of course, complex. Vehicle travel reductions are not the only way to reduce crashes — traditional traffic safety strategies are also important, and the two approaches are often complementary. For example, many targeted traffic safety strategies such as graduated driver’s licenses, special driver’s tests for seniors and anti-impaired driving campaigns become more effective and politically acceptable if implemented with multimodal planning, TDM incentives and Smart Growth policies so youths, seniors and drinkers can find convenient alternatives to driving.”

On the collapse of a bridge in Isabela
A hot topic these days is the collapse of a span of a newly built bridge in Isabela. The alleged causes of the collapse included truck overloading, design flaws and inferior construction. Initial news reports and statements put the blame on the trucker and the designer with only a few suspicions thrown at the contractor. And then the current President of the country together with his DPWH Secretary inspected the site together. BBM was later quoted as saying the cause was a design flaw.
The bridge’s designer came out to state that it is not his fault. That could have been perceived as a self-serving statement until you delve into his explanation and check his credentials. The designer happens to be one if not the most experienced bridge engineer in the country. He obtained his Bachelor’s and Master’s degrees in reputable institutions (UP and Virginia Tech in the US, respectively). He taught bridge engineering in universities and is perhaps instrumental in civil engineers choosing to specialize in bridges. And he was a past president of the Association of Structural Engineers in the Philippines (ASEP). He knew what he was doing and the process requires for his design to be reviewed and approved by the DPWH prior to having the bridge constructed. If it passed the DPWH review and approval process, then it should be determined if the contractor was faithful to the execution of the design. Photos spreading over social media shows problems where the structure failed. And the quick assessment of many who are knowledgeable about structural engineering and construction is that apparently, the failure is due to the construction.
What happened? Wasn’t construction progress monitored? Were there inspections to determined whether the design was followed? One result of the suspicions being thrown at the people responsible for the bridge is the proliferation of ‘corruption’ as the root cause of the collapse. There are already clever memes of the bridge employing ‘steal design’ and ‘steal reinforcement’ obviously replacing ‘steel’ in the terms. While we inject humor into the situation, we cannot deny how serious the matter is and the implications of design specifications as well as the emergence of new truck types with higher payloads is to pavement engineering in general and bridge engineering in particular.

Amusing vehicle accessories or features – are these legal?
I was amused by some memes and reels I saw on social media about cars getting these accessories that made them look like characters in the Disney series ‘Cars’. I finally saw the real thing as I was queued before Cainta Junction and on a truck.
A truck with eyes might be staring at you in traffic
So are these legal? I haven’t found anything yet that says they are. Perhaps they can be distracting to some people but they are not blinding like the super bright headlights (and even tail lights) that people install on their cars. What do you think about these accessories?

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?

Shared lanes in Baguio City – Loakan Road
I have several drafts of articles about our recent travel to Baguio City. Those include write-ups about roads to/from and in Baguio City. Before I post about Kennon Road and Marcos Highway, I want to share some examples of shared lanes I was able to take photos of while going around the city. The following photos were taken along Loakan Road near Camp John Hay. It is the same road that takes you Baguio’s airport.
Note the use of the international standard for bicycle pavement marking. This is different from the rather odd bicycle marking in the DPWH guidelines that looks like a person on a treadmill (among other interpretations).
The signs are also not standard and somewhat small as you can probably see in the photos.
Chevron signs for the curve
Another example of a curve section
There are actually two types of signs installed along the road – both state lane sharing but with the other directing bicycles to keep right.
Two signs alternated along Loakan road. This one directs bicycles to keep right.
Signs and pavement markings are closely spaced. Perhaps the intervals are less than 5 meters for the pavement markings?

Pedestrian crossing and fenced sidewalks
While shared rights of way (sharrows) or shared lanes is not preferred where there is space for bikes, these can be implemented for 2-lane roads with adequate lane widths such as Loakan Road. It is clear from the photos that there is ample if not generous space for cyclists and motorists to share a single lane. The premise for safety here is that motorists will not be hogging the road space, being mindful of cyclists, and will move at safe speeds.

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.

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 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. –
