On bicycles as a preferred mode of transport
Sharing this article on bicycles being the perfect mode of transportation. It is framed with respect to the concept of the 15-minute city. Here is the article:
Johnson, R. (April 19, 2023) “Embracing the 15-Minute City: 7 Reasons why Bicycles Are the Perfect Mode of Transportation,” Momentum Mag, https://momentummag.com/embracing-the-15-minute-city-7-reasons-why-bicycles-are-the-perfect-mode-of-transportation/ [Last accessed: 4/29/2023]
To quote from the article:
“Bicycles are aligned with the goals of sustainability and climate action, as they contribute to reducing greenhouse gas emissions, air pollution, and congestion. In a 15-Minute City, where the focus is on creating sustainable and climate-friendly communities, bicycles can be a powerful tool to achieve these objectives. By promoting cycling as a viable transportation option, cities can reduce their carbon footprint, mitigate climate change impacts, and promote a greener and healthier way of living.”

Article share: on pedestrian facilities and climate change
Here is an article that articulates the importance of walking and pedestrian facilities in sustainability and ultimately fighting climate change. It argues that if we had the infrastructure and facilities to make it easier for people to walk, they will and are likely to walk rather than use their cars. This is not limited to short trips as walking can be in combination with public transportation, making it an integral part of trips where public transportation covers the main commute and walking is the proverbial last mile travel.
To quote from the article:
“Walking, biking, and transit need to be prioritized, and treated as legitimate forms of transportation. This means stepping up efforts to collect data on sidewalks the way we do for roads, investing in complete walking networks before engaging in expensive new road projects and making sidewalk construction and maintenance a municipal responsibility rather than an individual one.”
Why do we keep widening roads?
I’m just going to share this article here. The article from The NY Times asks a question that has been bugging planners and engineers, particularly those who are in government and perhaps under the agencies like the DPWH, DOTr and NEDA. This also applies to planners, engineers and those from other disciplines involved in transportation infrastructure development and particularly roads or highways.

The wide Roman Highway, Bataan
As it is National Heroes Day today, I thought it would be nice to feature a road in an area that witnessed the experiences and sacrifices of many heroes. I traveled to Bataan last July and took some photos of the roads there including the Roman Highway, which is the main corridor connecting many of the province’s major towns. Also called the Roman Superhighway, the highway originally had 2 lanes (bi-directional and undivided) with shoulders along both side of the road. Eventually, it was widened and extended to 4 lanes (2 per direction) with wide shoulders. The current Roman Highway has been expanded to 6 lanes with shoulders but for most parts appear to effectively have only 4 lanes and paved shoulders.
The wide Roman Highway does not carry much vehicular traffic
The road widening is not complete as most bridges have not been widened. These produce bottlenecks like the one in the photo where the additional lane is effectively relegated to a shoulder.
The highway is practically straight but presents many examples of sags and crests. For those into highway engineering, images like the ones I share in this post are textbook examples for sight distance topics.
Another sag vertical curve with a bridge near or at the lowest point in the sag. Again, notice that the additional lanes are currently discontinuous at the bridge and there’s a barrier (orange) to warn motorists and guide them back to the original carriageway.
The highway is used by many trucks as there are industrial centers located along the highway including the PNOC in Limay and what used to be called the Bataan Export Processing Zone (BEPZ now the Bataan Freeport) at the end of the highway in Mariveles.
The widening of the Roman Highway includes the addition of one lane per direction and a narrow shoulder just before the sidewalks. The shoulder could easily be configured into a bike lane but that third lane can easily be designated for bicycles considering the traffic is usually light at most sections of the highway.
A section where the bridge has already been widened features 3 wide lanes per direction. The shoulders are still there but are not included in the bridge.
LGUs are joining the No-Contact Apprehension bandwagon
Another view of the wide highway
More on Bataan roads in a future post. I also took photos of the Gov. J.J. Linao National Road (Pilar – Bagac Road), which is the main access road to the Mt. Samat Shrine.

Cities and Automobile Dependence: What Have We Learned?
We end the year with an article from Todd Litman via Planetizen. The topic is something that we really need to ponder on as we or if we are to move towards more sustainable transportation for our cities and municipalities. The experiences during this Covid-19 pandemic should have provided us glimpses of how it could be if we put active and public transport above automobile dependence or car-centricity.

On the key transformations needed to achieve sustainable, low carbon transport
Also related to COP26, I am sharing material from the Sustainable Low Carbon Transport (SLOCAT) partnership, of which our center is part of. SLOCAT recently released the 11 key transformations for sustainable low carbon land transport urgently needed to meet the climate targets. Here’s a link to their site:
SLOCAT also has the following Wheel of Transport and the Sustainable Development Goals (SDG’s) on the same site. The Wheel illustrates the four cross-cutting themes: equitable, healthy, resilient and green.
In the SLOCAT site, they list the following to support the transformations:
Overarching approaches to apply across transport modes and sub-sectors overtime
- Put people first, not vehicles and technology
- Co-create and communicate a compelling vision and targets
- Guide short- and medium-term action with clear, coherent political messages
- Combine push and pull measures: Regulate and incentivise
- Link policies within and beyond transport for synergies
- Prioritise resources by social and sustainable value for money
- Engage, empower and coordinate stakeholders across government levels and sectors
- Build capacity and improve data
- Implement pilots to learn and share, then roll out at scale

On the 12 global road safety performance targets
The UN recently released the Global Plan for Road Safety. I’m just sharing their graphic on the global road safety performance targets:
I will try to discuss each one in future posts especially as I am involved one way or another in trying to realize these targets. Note, too, that these targets are further categorized among the five pillars mentioned at the foot of the graphic. These are (1) Road safety management; (2) Safer roads and mobility; (3) Safe vehicles; (4) Safe road users; and (5) Post-crash response.

On Transit, Urban Equity and Sustainability
Here is another quick share of an article about public transport, urban equity and sustainability:
Descant, S. (September 2021) “How Can Transit Deliver Urban Equity and Sustainability?”, Government Technology, https://www.govtech.com/transportation/how-can-transit-deliver-urban-equity-and-sustainability [Last accessed: 9/21/2021]
The article discusses how the Covid-19 pandemic clearly shows the role of public transportation in the lives of a lot of people. There is that opportunity to significantly if not radically improve public transportation now more than ever. Surely governments and their transit or regulating agencies have thought about this. While the pandemic led to situations that are not necessarily clean slates for many, there are definitely opportunities here and there to implement change that will increase benefits for transit users while attracting non-users to shift from their preferred modes (i.e., private vehicles). Here’s a takeaway from the article:
“We know that public transportation is the solution. So there needs to be a commitment at the federal level, not just in terms of funding, but also integrating public transportation deeper into the fabric of society, through land use policy and through other transportation access policies — the sidewalk and bike lane piece — with the data and payment apps as well…”
What improvements do you think should and can be done now given the pandemic situation? Are these still timely or have we figuratively “missed the bus”, so to speak?
On the burdens of car dependence
Here is a quick share today. This is another excellent article from Todd Litman who makes a great argument for why planning should move away from its being car-centric and contribute towards a significant reduction in society’s dependence on cars.
Litman, T. (December 15, 2020) “Automobile Dependency: An Unequal Burden,” Planetizen.com, https://www.planetizen.com/node/111535?utm_source=newswire&utm_medium=email&utm_campaign=news-12212020&mc_cid=e746a044a3&mc_eid=9ccfe464b1 .
Much have been said and written about this topic in many platforms including social media but in many of these, I noticed that the discussion often deteriorated into hating or shaming exercises rather than be convincing, constructive arguments for reforms in planning and behavior and preference changes in transport modes. Litman is always very fair and comprehensive and employs evidence or facts in his articles that should be clear for most people to understand. I say ‘most people’ here because there are still many who are among those considered as “fact-resistant”. Happy reading!

On mass transit and active transport
I recently gave a talk on transport in the new normal. There are a lot of materials that you can refer to if you want good visuals for a presentation. It helps to capture the attention and maybe the imagination of your audience, which in this case was varied. While I assume many to be in the physical, chemical & social sciences, and engineering, I knew that there were also people from media and those who were just interested in the topic. And so I made sure there were a lot of infographics mixed in with bullet points to drive the message clear about mass transit systems being the backbone of transport in highly urbanized cities, conventional transit like buses and jeepneys supplementing and complementing these, and active transport enabled and encouraged as a safe option for many.
I wasn’t able to include the following graphic shared by a friend advocating bicycle use especially for work and school trips. The following graphic comes from TUDelft, which is among the major universities in the forefront of research in transit and cycling. Clicking on the graphic will take you to their Facebook page and more links to their programs.
Note the essential information relating bicycles and transit in the graphic. Do we have similar data in the Philippines (or at least for the National Capital Region)? I hope this stirs interest for research work. There are a lot of topics to take on including even data collection to capture the information required for substantial studies on cycling, transit and their relationship.

Caught (up) in traffic
