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.

Designing a “Runnable” City
I’m sure you’ve read or heard about walkable cities. But have you read or heard about “runnable” ones? Here’s a quick share of an article about cities where you can run, jog or walk.
Source: Designing a “Runnable” City
To quote from the article:
“Several urban design principles can enhance the runnability of a city:
Connectivity and accessibility: This means developing a network of interconnected running paths and trails that are easily accessed from various parts of the city (especially neighborhoods). Even better if can be green corridors that connect to other parks and open spaces, and support continuous movement.
Safety and security: Ensuring running paths are well-lit and separated from vehicle traffic is crucial. Traffic calming measures such as vehicle lane narrowing, wider footpaths, and appropriate landscaping enhance runner safety. Street trees also help reduce car speeds, as they alter our perception of how wide the road is and provide a psychological cue that we’re in a residential area. Redesigning urban infrastructure to include dedicated running paths alongside walking paths and bicycle lanes, is a great idea.
Inclusive design: City design should encourage active mobility, which means including benches, water fountains, and restrooms along running routes. It means building footpaths that enables running, and avoiding uneven, slippery or unfavorable surfaces such as cobblestones. It also means making it easy to find your way around — even in unfamiliar environments.”

Initial thoughts on driverless cars
The wife is currently in San Francisco in the US. She sent me some photos and videos of the driverless car ahead of booked to get to their office there.

The first thing that came to mind seeing the photos and videos is “It’s cool!” Their creation and operation are indeed wonders from an engineering and technology standpoint. Unfortunately, these are not the solution to our transport problems. These will just replace the cars we already have and causing congestion and other concerns.

On trees as solution to many of our urban problems
I am sharing this nice article on trees being the solution to many of our urban problems. I think many people have come to notice the importance of trees and the role they play with the increasing temperatures (i.e., heat) we’ve experienced the past years. The science on this state much more and covers not just temperatures but flooding, energy and infrastructure as well. Discussions and examples on these are in the article:
Durand-Wood, E. (August 8, 2024) “The Multi-Tasking Marvel: How Street Trees Can Solve Many Municipal Problems,” Strong Towns, https://www.strongtowns.org/journal/2024/8/8/the-multitasking-marvel-how-street-trees-can-solve-many-municipal-problems [Last accessed: 8/28/2024]
To quote from the article:
“Planting and maintaining street trees is an investment, but it’s one that pays for itself over and over again. Cities around the world are starting to calculate the economic value of their urban forests, a task made feasible with tools like i-Tree.
And more research is finding that trees pay for themselves many times over. A U.S. Forest Service study “conducted in five U.S. cities found that every dollar invested in the management of urban trees [ …] yields annual benefits of $1.37 to $3.09.
Trees are also the perfect example of a small bet. They cost relatively little, but the many varied returns are so high.”

On mountain biking and its history
Here is another quick share of a rather informative and amusing article about cycling, particularly about mountain-biking:
Septer, Q. (June 29, 2024) “The Poetry of Cycling,” Medium.com, https://medium.com/the-new-outdoors/the-poetry-of-cycling-dffeb752b510 [Last accessed: 8/24/2024]
To quote from the article:
“Mountain biking continues to ascend in popularity. New trails are built. New records are set. New technologies are fine-tuned to the subtleties of the sport’s sub-disciplines. But the ethos of mountain biking hasn’t changed all that much since the days of the Buffalo Soldiers, more than a century ago, when folks simply wondered how far a bicycle might take them.”

Pedestrian-Friendly Cities: The Impact of Walkability Grants
Here is a quick share of an article on how to encourage cities to be more pedestrian-friendly:
Source: Pedestrian-Friendly Cities: The Impact of Walkability Grants
Many of our cities, particularly the highly urbanized ones, are not as walkable as we want them to be. Lacking are the most basic facilities such as sidewalks and safe crossings. Walkability Grants such as those in the US can encourage cities to build and/or enhance pedestrian infrastructure. Many designs such as those footbridges along EDSA and Commonwealth Avenue, for example, are anti-walking. Grants may be used to come up with better designs for walkways and footbridges.
To quote from the article:
“Walkability grants are awards for programs and projects creating innovative pedestrian infrastructure, such as new sidewalks, crosswalks, plazas, street lights and green spaces. For example, in February 2023, the Biden-Harris Administration announced the Safe Streets and Roads for All Grant Program, delivering $800 million in monetary awards for 511 projects addressing public safety and road improvements…
Reshaping the built environment into a walkable haven helps boost the local economy and sustainability. By changing the urban landscape, citizens are more inclined to walk instead of drive, allowing cities to reduce emissions, improve air quality and create healthier neighborhoods. This is critical, considering air pollution is responsible for 7 million early deaths yearly.”
Perhaps we can have similar grants coming from national government via the Department of Interior and Local Government (DILG) in cooperation with the Department of Transportation (DOTr) and the Department of Public Works and Highways (DPWH)? There was some funding for bikeways during the pandemic but this new one should put more emphasis on walkability.

Article share: on how transportation impacts your health
I’ve written or shared articles here about transportation and health. I share another article concerning how transportation impacts our health. Here’s our first article share this August:
Harris, A. (August 1, 2024) “Getting there is half the battle: how transportation impacts your health,” The Flint Courier News, https://theflintcouriernews.com/getting-there-is-half-the-battle-how-transportation-impacts-your-health/ [Last accessed: 8/14/2024]
To quote from the article:
“In health, transportation is essential to how people access health care and maintain health,
whether it is getting to the doctor, picking up medication from the pharmacy, going to the
grocery store to maintain nutritional needs, or walking around their neighborhood to get more
exercise.”

Post Habagat Aerial Photos
We flew to Iloilo just after the Habagat floods that ravaged much of Metro Manila and its surrounding provinces. As our plane took off from Runway 13-31, I figured there was an opportunity to take a few photos of Metro Manila especially as I was seated by the window of the plane.










More aerial photos to be posted here soon!
