On defining the 15-minute city

I have shared articles and briefly written about the concept of the 15-minute city on this blog. Here is another discussing how a 15-minute city is defined:

(February 8, 2021) “Defining the 15-minute city,” Public Square, [Last accessed: 8/10/2021]

Here is an image from the article:

Again, it is important to contextualize these concepts. I share these as references and topics for discussion. Of course, I have my own opinions about this and I have written about those in previous posts. I guess in the Philippine context, we can include the pedicab or non-motorized three-wheelers in the discussion. These are also very popular modes in many cities and municipalities despite their being also prohibited along national roads like their motorized counterparts. It would be nice to have more visuals in the form of maps that show travel times for essential destinations or places like hospitals, markets, grocery stores, workplaces and, of course, homes. I assume there is at least someone, somewhere who perhaps have made multi-layer maps of this sort and attempted to related them along the lines of this concept of a 15-minute city (or perhaps the even older “compact cities”).

On quantifying the benefits of bike share

I’m sharing another article that presents a quantification of Such articles and studies are gaining interest as cycling or biking becomes a popular choice for many seeking an alternative to their usual or former modes of transport. It helps that there are many initiatives promoting active transport in general and cycling/biking in particular.

Wilson, K. (July 23, 2021) “Study: Bike Share Saves the U.S. $36 Million Public Health Dollars Every Year,” StreetsBlog USA, [Last accessed: 8/6/2021]

While the article is about bike share, the conclusions can be extended to cycling/biking in general. The article points to at least 3 major areas where benefits can be derived: safety, air pollution (reduction) and physical activity. To quote:

“I think the message to cities is that bike share — and biking in general, though that’s harder to quantify in the way we do in this study — can contribute a lot to their long term goals,… Most cities want to improve quality of life, the economy, the climate, and their public health outcomes. Bike share does all those things.”

On the other benefits of cycling – pavements

Here is a very interesting article that tackles a not so obvious benefit of switching to cycling:

Dion, R. (July 12, 2021) Biking’s Billion-Dollar Value, Right Under Our Wheels,” Planetizen, [Last accessed: 8/4/2021]

To quote: “A strategic switch to biking would dramatically reduce the depth of roads, saving untold billions over the next generation.”

This is relevant from the perspective of highway engineering particularly concerning pavement design, construction and maintenance. It is intriguing, too, since pavement design (and consequently pavement thickness) is not necessarily correspondent to light vehicle traffic volumes. In the Philippines, for example, only heavy vehicles are considered for the pavement load estimation. It is assumed that light vehicle traffic, which compose most of the traffic along roads contribute mainly to pavement weathering rather than structural aspects.

Sharing an article on the benefits of cycling exercise

Here is another quick share of an article on the benefits of cycling. The article is more about the health benefits that are highlighted here with a study on diabetics:

Putka, S. (July 26, 2021) “One type of exercise reliably lowers your risk of death, says scientists,” Inverse, [Last accessed: 7/28/2021]

The article is clear about the impacts not being limited to diabetics or those with other illnesses. Also, while intensity and duration of exercise are mentioned and appear to have the most significant positive effects, the findings extend to relatively healthy people as well as those into lower intensity, less duration exercise. The key is still to be active. Of course, a healthy diet should also be a constant across these cases.

On riders’ perception of safety

The Federal Highway Administration (FHWA) of the US Department of Transportation released some infographics recently to highlight road safety. One very timely and relevant graphic image asks about which facilities make bicycle riders feel safer:

There were some initial reactions when I shared this on social media with one immediately criticizing share-use paths and citing the one along Marcos Highway (stretch under Pasig, Marikina, Cainta and Antipolo) as an example. I quickly explained that the graphic assumes good designs instead of the flawed one along Marcos Highway. In fact, the shared use path is also quite popular in Europe and particularly in the Netherlands where they have many examples of these paths stretching for kilometers that are exclusive to active transport (pedestrians and cyclists). The good designs need to be shared and circulated so people will know about what they look like and learn about their features. These can be adopted and adapted to local situations.

Did you notice the images of cyclists/riders at the top of the graphic? These are important, too, because they provide context in terms of the type of riders who are the targets for infrastructure and campaigns that support and promote cycling across different types of people. Cycling shouldn’t just be for the most fit or the weekend warriors but rather for everyone who could take it up and not just for recreation but for everyday, utilitarian use (e.g., commuting, shopping, etc.).

Another look at the ‘avoid, shift and improve’ framework

The transport and traffic situation during this pandemic has revealed a lot about what can be done and what needs to be done about transportation. Discussions about what and how people visualize their ideal or acceptable transportation system reminded me of the backcasting concepts and the tools. The following diagram is sourced from the SLoCaT homepage:

Examples (i.e., non-exhaustive list) of avoid, shift and improve measures

Note the overlaps among the three? Do you think its possible to have a measure that’s avoid, shift and improve at the same time?

Note, too, that if we contextualize this according to the Covid-19 pandemic, these measures even make more sense rather than appear like typical, ordinary measures we have about transportation. The pandemic revealed many weaknesses or vulnerabilities of our transportation system. We are presented with the opportunity to address these and implement certain measures that would have met with a lot of opposition before but can probably be rolled out now such as public transport priority schemes and protected bike lanes. “Work from home” is not really new since the concept has been proposed and implemented before but not as widely as was required by the pandemic situation. So perhaps we should take advantage of this forced reboot of sorts for our transportation system to be able to implement this A-S-I framework.

On step counts

Here’s a nice read about whether we need to reach 10,000 steps/day. We often hear or read about people asking how many steps you’re taking on average each day or lamenting or bragging about how many they’re taking each day. Perhaps we don’t really have to take so many? And maybe the key is really about our diets.

Apparently, there is really no need to reach that so-called magic number that is 10,000 steps.

Article on the new mobilities

Here’s a quick share of an article on what is described as the new mobilities:

Litman, T. [June 30, 2021] “Planning for New Mobilities: Preparing for Innovative Transportation Technologies and Services,”, [Last accessed: 7/3/2021]

What exactly are these new mobilities? To quote from the article:

“New Mobilities

  1. Active Travel and Micromobilities. Walking, bicycling, and variations, including small, lower-speed motorized vehicles such as electric scooters, bikes, and cargo bikes.
  2. Vehicle Sharing. Convenient and affordable bicycle, scooter, and automobile rental services.
  3. Ridehailing and Microtransit. Mobility services that transport individuals and small groups.
  4. Electric Vehicles. Battery-powered scooters, bikes, cars, trucks, and buses.
  5. Autonomous Vehicles. Vehicles that can operate without a human driver.
  6. Public Transport Innovations. Innovations that improve transit travel convenience, comfort, safety, and speed.
  7. Mobility as a Service (MaaS). Navigation and transport payment apps that integrate multiple modes.
  8. Telework. Telecommunications that substitutes for physical travel.
  9. Tunnel Roads and Pneumatic Tube Transport. New high-speed transport networks.
  10. Aviation Innovation. Air taxis, drones, and supersonic jets.
  11. Mobility Prioritization. Pricing systems and incentives that favor higher-value trips and more efficient modes.
  12. Logistics Management. Integrated freight delivery services.”

Guidelines pertaining to bike lanes in the Philippines

The Department of Transportation (DOTr) and the agencies under it are now promoting bicycle use. Part of the campaign is to improve the safety of cyclists, most especially those using bikes for commuting (e.g., bike to work). Recently, the agencies have posted infographics showing the guidelines for bicycle lanes. Here is one from the Land Transportation Office (LTO), which is in-charge of vehicle registration and the issuance of driver’s licenses:

These are still basically guidelines that apparently do not carry a lot of weight (i.e., no penalties mentioned) in as far as enforcement is concerned. As they say, these appear to be merely suggestions rather than rules that need to be followed or complied with. Perhaps local government units can step in and formulate, pass and implement ordinances penalizing people violating these guidelines? These penalties are important if behavior change among motorists is to be achieved.

Are roads really designed just for cars?

The answer is no. Roads were and are built as basic infrastructure for transport no matter what the mode. However, the standards for dimensions (i.e., number of lanes, widths, etc.) are based on the motor vehicle capacity, and structural standards (i.e., thickness, strength, reinforcement, etc.) are based on the weights they are supposed to carry over their economic lives. The pavement load as it is referred to is usually based on the cumulative heavy vehicle traffic converted in terms of the equivalent standard or single axles or ESA. An ESA is 18,000 pounds or 18 kips in the English system of measurements or 8.2 metric tons in the Metric system.

A typical local road – is it really just for cars or is it also for walking and cycling? Or perhaps animal drawn transport? 

A colleague says many of the posts in social media pitting bicycles with cars are already quite OA (overacting). I tend to agree as I read how people generalize roads being car-centric. Roads have been built basically to serve a avenues for transportation. They were improved over time in order to have more efficient ways to travel by land. It didn’t hurt that vehicle technology also developed over time and bicycles somehow became less popular than the cars and motorcycles. The motorcycle itself evolved from bicycles so in a way, it is the evolved and mechanized form of the two-wheeler.

In a perfect world, people would be sharing the road space and it would be equitable among different users. In a perfect world perhaps, it won’t be car-centric as there would probably be better public transport options and transit will be efficient, reliable, comfortable and convenient to use.

The reality, however, is that we do not live in a perfect world and transformations like the ones being pitched on social media are nice but are also not as inclusive and equitable as their advocates claim them to be. I’ve always said and written that you cannot simply change transportation without also implementing changes in land use and housing in particular.

Why do we need wide roads connecting suburbs and urban areas? Why is there sprawl? Why do people live in the periphery of CBDs or the metropolis? It is not just about transport though it seems easier to focus on this. Even transportation in Japan, with Metropolitan Tokyo and its equivalent of NCR plus as a subject, needs to be properly contextualized for land use and transport interaction and development. It seems that even with a comprehensive and efficient railway network, there are still shortcomings here and there. We don’t have such a railway network (yet) so we need to find ways for easing the currently long and painful commutes many people experience on a daily basis. That means continued dependence on road-based transport and trying to implement programs and schemes to improve operations.
