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.
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.
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.
The main article may be found here (in proper citation for academic/researchers reading this):
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.
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!
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.
Here’s a quick share of a very nice article that’s very informative and therefore useful to people seeking to tap into the potential of shared transportation to help alleviate transport woes in their cities and towns:
Miller (2019) “9 Ways Cities Can Unlock the Potential of Shared Transportation”, Medium.com, https://medium.com/frontier-group/9-ways-cities-can-unlock-the-potential-of-shared-transportation-66a53b2c841 [Last accessed: May 3, 2019]
So far, we only have few examples of shared transportation in the Philippines. These include a few bike shares in Metro Manila and does not count ride-hailing/ridesharing, which we now know is not really a sustainable form of transport.
Here is another quick post on another article I am sharing showing the importance of sustainable transport:
Milner, D. (2019) How sustainable transport can save the world, medium.com, https://medium.com/@djjmilner/how-sustainable-transport-can-save-the-world-f2f64517dc52 [Last accessed: 4/9/2019]
It goes without saying that sustainable transport has a lot of potential for helping mitigate climate change and other issues but much is expected of our leaders for policies and program & project development & implementation towards achieving sustainable transport in our cities and municipalities.
