On bicycles vs. self driving cars

You’ve probably seen this graphic, the top part of which is attributed to the Cycling Promotion Fund. The last image is reproduced in the lower part of the image but labeled to emphasize what space is required to transport 48 people on electric cars and autonomous or self-driving cars.

 

It is quite obvious that even if the current fleets of cars are replaced by electric and self-driving models, they will practically be the same problem in terms of road space occupied and the resulting congestion. So perhaps e-cars or autonomous cars are not really the solution we are looking for.

There is this nice article where the author articulates the how bikes (and active transport in general) should be the a more essential part of future transport and society than the automobile:

Collignon, N. (September 9, 2022) “Bikes, not self driving cars, are the technological gateway to urban progress,” Next City, https://nextcity.org/urbanist-news/bikes-not-self-driving-cars-are-the-technological-gateway-to-progress [Last accessed: 9/16/2022]

There are two quotable quotes from the article that I want to highlight here:

“Today the potential benefits from cycling on health, congestion, pollution and CO2 emissions are crystal clear and increasingly quantifiable, but the benefits of self-driving vehicles remain hazy. When ride-hailing companies like Uber and Lyft promised lower congestion and reduced car ownership, they instead increased congestion and led to a decline in transit ridership.”

and

“The concept of “jaywalking,” for example, is integral to the “car technology” of today. The crime of crossing a street without respecting the dominance of cars was invented by the car industry in the 1920s, who pushed hard to define streets as a place for cars, not people. Our car technology today is also defined by the restriction of movement it imposes on people.

When we begin to see technology through the lens of systems, it becomes clear that genuine technology-led progress will focus on dealing with the accelerating complexity of today’s world, not increasing the complexity of our tools.”

On micro transit and transportation gaps

I’ve written and shared articles before on how Paratransit, bicycles and micro transit helps alleviate the transport demand problems we are experiencing especially in highly urbanized cities. I think we should have as many options as possible for transport while also working towards the reduction of dependence on cars. Here’s an article that relates about experiences in the US:

Zukowski, D. (September 13, 2022) “Cities turn to microtransit to fill gaps in public transportation,” Smart Cities Dive, https://www.smartcitiesdive.com/news/microtransit-public-transportation-gaps-jersey-city-via/631592/ [Last accessed: 9/15/2022]

To quote from the article:

“Microtransit options are also helping to reduce the reliance on personal cars. “We’ve received feedback from people who say that because of Via they are now more consistently leaving their personal vehicle at home and using Via instead to travel within the city, which is exactly the kind of thing we want to see happen,” said Jersey City’s Patel.”

This final statement or paragraph in the article sums it up very well. Of course, we have to note that the experience in Asia is quite different especially in Southeast Asia where motorcycles are very popular and still on the rise in terms of their mode shares. While these may be considered micromobilities in western countries, they are definitely motorized private vehicles that, depending on how they are used and how the rider behaves, may be beneficial but at the same time also very dangerous for people.

On electric vehicles and informal transport

I’ve been involved in studies on electric vehicles and their applications in the past. I continue to take part in studies about informal transport including continuing research on motorcycle taxis or “habal-habal” as they are called in the Philippines. The combination of the two is an interesting research area and there are many topics that can be developed as we determine the most appropriate applications for electric vehicles. Here is an interesting article on electrifying informal transport that sets the context for research:

Ribet, L. (August 30, 2022) “The role of data in electrifying informal transport,” Slocat partnership, https://slocat.net/the-role-of-data-in-electrifying-informal-transport/ [Last accessed: 9/9/2022]

To quote from the article:

“However, electric two-and-three wheeler startups, informal transport retrofitting pilots and e-bus initiatives cannot be the only answer to the mobility challenges facing developing cities. Phasing out oil-reliant public transportation is needed and investing in electric mobility solutions may well improve the overall picture quite substantially, but there is a far larger challenge that is omitted from these ambitions: addressing the complex operations of informal transport systems that characterise lower-income countries’ urban mobility. Electrifying minibus taxis is not synonymous with more reliable, affordable and convenient public transport, and we need to prioritise the understanding and improvement of overall informal transport systems data first.”

 

 

On addressing global warming

Here is another quick share of an article; this time on “warming”. The evidence for global warming is strong and we need to address this pressing issue if future generations are to survive a planet that is heating up fast.

Litman, T. (August 31, 2022) “Cool Planning for a Hotter Future,” Planetizen.com, https://www.planetizen.com/blogs/118535-cool-planning-hotter-future?utm_source=newswire&utm_medium=email&utm_campaign=news-09012022&mc_cid=ead7ee914a&mc_eid=9ccfe464b1 [Last accessed: 9/5/2022]

To quote:

“Many of these strategies provide significant co-benefits. For example, reducing road and parking supply with more efficient traffic and parking management helps reduce infrastructure costs and traffic problems, and by reducing impervious surface area it reduces stormwater management costs. Planting more urban shade trees helps create more attractive neighborhoods and increase wildlife habitat. Improving natural ventilation creates more comfortable and healthier buildings, as summarized below.”

I recall people calling for more trees to be planted along roads and how our city streets can become something like Orchard Road in Singapore. I agree with having more trees and other plants, landscaping, along our roads. I also lament the times (and it continues) when the DPWH chopped so many old trees along national roads for road widening projects that didn’t need to destroy so many that gave those roads shade as well as character. We need more change in mindsets particularly when we design highways and streets towards sustainability and yes- reducing heat.

On the impacts of bicycle use

I’ve probably read a lot of posts on social media advocating for bicycle use. Here is another article that provides us with evidence about the impacts of cycling on travel, emissions and health:

Timmer, J. (August 20, 2022) “Here’s What Happens When Countries Use Bikes to Fight Emissions,” Wired, https://www.wired.com/story/bike-more-curb-global-emissions/ [Last accessed: 8/24/2022]

To quote from the article:

“Globally, adopting a Danish level of bicycle use would reduce annual emissions of CO2 by 414 million metric tons, approximately equivalent to the UK’s emissions in 2015. Boosting that to a Dutch level would eliminate nearly 700 million metric tons, or most of the emissions from Germany in that year.

The researchers also noted that countries like the Netherlands and Denmark have much lower rates of obesity than their peer countries. Based on the known health risks there, they estimate that, globally, we’re already avoiding 170,000 deaths annually due to cycling. Expanding this globally, they found that Denmark-equivalent bicycle use would prevent 430,000 deaths per year. Dutch levels of cycling would prevent 780,000 deaths.

That said, the vulnerability of cyclists to cars poses its own lethal risks. But these aren’t anywhere close to outweighing the benefits from exercise and lower obesity. (They’d add about 90,000 and 160,000 additional deaths per year for the two levels of use.) And if fewer drivers are using cars, there’s a chance that those numbers would come in even lower.

It’s worth noting that these numbers almost certainly underestimate the benefits of shifting to bikes. Bicycles use far fewer resources to produce, and they last longer than most cars. Maintenance is likely to be far less resource-intensive as well. So simply focusing on the use of the bike omits a lot of things that would show up in a detailed life-cycle analysis.

The researchers are certainly correct that there are a lot of locations where weather makes cycling a less-than-ideal option—and the range of places where heat makes it a positively dangerous option is expanding in our changing climate.

But some of the other issues are less severe than they might appear at first. For example, the advent of bicycles with electric assist means that hilly locales aren’t necessarily the barrier they might have been a decade ago. And while a number of countries have large open spaces where cars will remain a necessity, the trend toward urbanization means that most people in those countries will live in places where cycling can be made an option.

So, the biggest barrier is likely to remain the social will to rethink transportation.”

Indeed, social will (as well as political will) is perhaps the biggest barrier in our country. Many people may not agree but the evidence for this is so clear and obvious  that one has to be naive or oblivious to not see it. How else will one explain people sticking to their cars and more readily shifting to motorcycles rather than the bicycle. Of course, there are other factors to be considered and the article actually cites wealth and geography as strong prerequisites in developing a cycling culture. We need to do much more to determine where interventions are needed including land use planning and land development as well as the provision of affordable housing closer to workplaces, schools, shops and other places of interest (Hello 10- or 15-minute cities!).

 

Free public transportation services?

We start August with an article share. Much has been said and written about public transportation being a basic right for people. And the experiences during this Covid-19 pandemic have shown us just how efficient and adequate public transportation can help make our lives better in terms of addressing our commuting or travel needs. Here is a very informative article that should make sense from the perspective of the general commuting public:

Konbie, N. (July 29, 2022) “The Case for Making Public Transit Free Everywhere,” Wired, https://www.wired.com/story/free-public-transit/?bxid=5bd6761b3f92a41245dde413&cndid=37243643&esrc=AUTO_OTHER&source=EDT_WIR_NEWSLETTER_0_DAILY_ZZ&utm_brand=wired&utm_campaign=aud-dev&utm_content=WIR_Daily_072922&utm_mailing=WIR_Daily_072922&utm_medium=email&utm_source=nl&utm_term=P7 [Last accessed: 8/1/2022]

To quote:

“Free fares might not get everyone out of cars, but will convert some journeys, which benefits everyone in terms of carbon reduction and improving local air quality—and even helps drivers by calming traffic. Free fares won’t pull low-income people out of poverty, but will keep money in their pockets and ensure everyone can travel when they need to. Ditching fares comes at a cost, but there are savings to be had by not investing in expensive ticketing systems and wider logistical and societal benefits…
Public transport should be considered a human right, alongside access to health and education.”

Of course, service quality is a major concern here in the Philippines but isn’t it everywhere else? The question of sustainability should be a rather complex one considering we haven’t truly understood and translated the benefits that can be obtained from providing high quality public transport services vs. being car-oriented. Congestion pricing, for example, could very well provide the funds to improve, upgrade and maintain desirable public transport services (i.e., desirable from the perspective of most commuters and not just the lower and middle income people who more regularly or likely to take public transport than other modes of transport).

Bike lanes at the UP Diliman campus – Part 2

The bike lanes in UP Diliman are not limited to the Academic Oval. There are now also bike lanes along other major roads including Magsaysay Avenue, which is road immediately after the portal at the Asian Center and allowing direct entrance and exit via Katipunan Avenue (C-5). The bike lanes are along either side of Magsaysay Avenue and are of Class II – Type B (separated bike lanes) but there are no  LED markers that are ideally placed along the delineation for the bike lanes.

On the benefits of developing and investing in active and public transportation

Here is another quick share of an article with a very relevant and timely topic – the business case for multimodal transport planning:

Litman, T. (July 2022) “The Business Case for Multimodal Transportation Planning,” Planetizen, https://www.planetizen.com/blogs/117697-business-case-multimodal-transportation-planning?utm_source=newswire&utm_medium=email&utm_campaign=news-07142022&mc_cid=03c159ebcf&mc_eid=9ccfe464b1 [Last accessed: 7/15/2022]

To quote from the article:

“Conventional planning tends to undervalue non-auto mode improvements by assuming that each additional mile of their travel can reduce, at best, one vehicle mile traveled. In fact, in many situations they can leverage much larger reductions in vehicle travel, meaning that each additional mile of walking, bicycling, or public transit can reduce more than one vehicle mile … As a result, walking, bicycling and public transit improvements can provide much larger vehicle travel reductions and benefits than is commonly recognized.”

There is a box referred to in the preceding quote. I will not reproduce it here so I leave it up to the reader to go to the original article by Litman to find out how active and public transport can leverage additional travel reductions. Understanding these and the extend by which we can be independent of car-use (referring to non-car travel demand) will allow for a better appreciation, travel-wise and economics or business-wise, of the advantages of developing and investing in active and public transportation infrastructure and services.

Bike lanes at the UP Diliman campus – Part 1

I had first read about the enhanced bike lanes at the UP Diliman Academic Oval last month from a social media post of a friend. She was present as the delineations of the jogging and cycling lanes were being painted along with the baybayin marks distinguishing UP’s bike lanes from others like it. UP’s bike lanes predate the current ones around Metro Manila that mostly popped-up during the pandemic.

The Academic Oval road original had two-way traffic along its wide carriageway, that could easily fit 4 lanes. Since it became a one-way, counterclockwise road, the lanes had been divided into 3 wide lanes with one lane initially committed to bicycles.

Here are the two lanes designated for joggers/walkers (curbside) and cyclists (median). The pedestrian sidewalk was originally planned to be widened in time for UP’s Centennial celebration back in 2008. That did not materialize. The Academic Oval could have had wider sidewalks for those who are not walking for exercise.

The section in front of Melchor Hall features the words bicycles or bike lane and pedestrian in baybayin. Its certainly a novelty for now and something probably apt for the campus roads but not necessarily for others.

A closer look at the baybayin script along the jogging/walking and bike lanes.

Here’s the bigger picture on the pavement markings.

Approach to an intersection 

The UP colors inform riders about the intersection ahead. These are more visual as they are flat and not rumble strips. The older pavement markings advising riders of the speed limit should be seen in the context of utilitarian cycling (e.g., bike to work, bike to school) rather than cycling for fitness or recreation, which obviously may involve higher speeds and is frowned upon along the oval.

The intersection approach from another angle.

The Academic Oval bike lane is one of the original recommendations of a transport study conducted for the campus about 17 years ago. The study was the basis for the campus being declared as a road safety zone, which among others included a provision for its roads to have a 30-kph speed limit. The one-way counter-clockwise traffic circulation and the jogging and bike lanes, however, are officially a part of what has become a long-term experiment on campus. There are many who oppose the one-way scheme and are vehement against the ultimate plan to have the Academic Oval car-free or car-less (it is mostly car-less during Sundays – part of the “experiment”).

A Bike Master Plan for Metro Manila, Metro Cebu and Metro Davao

Before Active Transport Week concludes this weekend, I would just like to share this collage from one of our staff at the National Center for Transportation Studies of the University of the Philippines Diliman. It is about the Master Plan developed for the three metropolitan areas in the country – Metro Manila, Metro Cebu and Metro Davao.  I will share more details about this soon including a link or links to where you can download a copy of the plan.

The project concluded recently with the submission of the Final Report but most important is the Master Plan document that can serve as a reference for further development of bike lanes in the metropolises. I’ve seen the Master Plan and many of its provisions and recommendations can easily be adopted or is replicable in other cities and municipalities in the country. Perhaps, there should be a National Master Plan?
