Pavement distress along C-5 due to the truck lane policy

I frequently use Circumferential Road 5 (C-5), which is known by many names according to the MMDA, the DPWH and the LGUs it passes through. One thing I always notice is the deteriorating or deteriorated pavement, particularly along the lane designated for use by trucks. The MMDA had instituted and implements a policy requiring large trucks to use one lane of C-5 during times when the truck ban is lifted (10:00 AM to 4:00 PM). Smaller trucks are allowed to use other lanes.

The result has been a long platoon of large trucks along the designated lane of C-5 and this concentration of load on the highway has caused faster pavement deterioration for that lane. This is especially evident when the pavement surface is of asphalt concrete. Flexible as it is, the concentration of load has led to obvious pavement deformation as shown in the following photo.

For Portland cement Concrete pavement (PCCP) cases, I would presume that there is also significant damage and the distresses (e.g., cracks) can be linked to this concentration of load. This situation and the conditions for loading likely have detrimental implications on maintenance costs for C-5 and is probably an unintended consequence of the MMDA’s policy. It would be interesting to quantify the impacts of this truck lane policy, whether it has contributed to improve traffic flow along the major thoroughfare, and whether the maintenance costs have risen (and by how much) from the time the policy was implemented.

List of infrastructure projects for the Philippines’ BuildBuildBuild initiative

I was looking for a list of projects said to be prioritized by the current administration in the Philippines and mentioned in the presentation made by government yesterday. Here’s one I found from GMA News:

Infrastructure projects lined up by the Duterte administration

Noticeable for me are the following:
1. No mention of major bridge projects that were heavily hyped both on mainstream and social media – these bridges include those that were proposed to connect the islands of Panay and Negros, Negros and Cebu, and Cebu and Bohol. It doesn’t mean, of course, that these have been abandoned but likely only sidelined for the moment.

2. Break-up of Clark Green City into several components – this seems to be a more realistic approach especially considering how big and complex this project is, and how many agencies or entities are and will be involved

3. Mass transit projects in Metro Manila – these include big ticket projects such as the proposed subway, BRT and the rehabilitation of PNR lines. These are all projects that should have been done a long time ago but for various reasons have been delayed. Say what you will about so much resources being poured into Metro (Mega?) Manila but it is the economic center of the country and efficient transport will go a long way in generating resources that can eventually be used in other parts of the country.

4. Emphasis on Clark Airport – it seems to me that the current administration is focused on developing Clark as the alternative (if not the main) gateway to the greater capital region. This is a departure from the hype we have received about a replacement for NAIA including one that was proposed at Sangley Point in Cavite.

5. Scaling down of Mindanao Railways – instead of pushing for a much grander (and unrealistic I think) railway project for the entire island, they identified a more realistic and perhaps practical line connecting Tagum, Davao and Digos. One colleague noted, however, that this corridor is already heavily serviced by buses and vans so rail ridership is at best threatened from the start.

What’s your take on the proposed projects and the list in general?

Incentives for not driving?

There’s a nice article on Wired that argues for giving an incentive to commuters to give up driving (i.e., using their cars to go to/from workplaces). My only comment here is that it might have better chances elsewhere but not in the Philippines where such incentives often are seen as dole-outs and, despite guidelines or rules for implementation, are likely to be abused or taken advantage of in many offices. This is especially true when cities do not have good quality public transportation and you have low priced motorcycles and cars on sale with the many dealerships. Sad to say but the Philippines is not ready (not mature enough?) for such schemes.

Want commuters to ditch driving? Try giving them cash money

The article is by Aarian Marshall and appeared on the online version Wired last March 26, 2017.

First call for papers for the TSSP 2017 conference

The first call for papers for the 24th Annual Conference of the Transportation Science Society of the Philippines came out last Wednesday, Feb. 15:


Mobilizing sustainable transport for development

The United Nations (UN) has recently published a new report on “Mobilizing sustainable transport for development” authored by a High Level Advisory Group on Sustainable Transport formed by the UN. The report and other resources may be found at the following website:

Secretary General’s High Level Advisory Group on Sustainable Transport

This is under the UN’s Sustainable Development Knowledge Platform. You can check out the other materials at the website. The UN has many initiatives on sustainable transport and has been very active in promoting or advocating for sustainable transport for a long time now. It is through the UN Centre for Regional Development (UNCRD), for example, that the Philippines and other ASEAN countries were able to formulate their national EST strategies. The new report continues on the UN’s commitment to promote sustainable transport to improve people’s lives around the world.

Better indicators than GDP

A friend shared this article on social media:

Five measures of growth that are better than GDP

The article explains in clear and simple terms five better indicators of growth and development than what is regarded as the conventional and traditional measure that is gross domestic product (GDP). There is an analogy in the article using speed, a parameter in traffic, to explain how GDP is insufficient in describing growth in a more complete manner. For example, in the Philippines, the significant increase in GDP over the last 6 years has been mentioned as proof of economic growth. While this is true, many people could not appreciate this growth since there is the perception is that it is not inclusive. That is, economic development is not felt by many who are in the lower income classes.

Speed, indeed, is not enough to describe the transport situation along a road considering that there are other metrics needed to have a more complete picture of transport and traffic conditions. I will talk about this in another posting soon.

Are Filipinos willing to pay for good public transportation?

There is a nice article that appeared last April 1, 2016. I hope it is not an April Fool’s type of an article.

Why is the U.S. unwilling to pay for good public transportation?

Reading the article reminded me of a lot of similar concerns surrounding public transport projects currently being constructed and those in the proposal and pipeline stages in Philippine cities. It seems though that there are still many people who have little appreciation of the benefits of modern public transport systems. Aside from Metro Manila and perhaps Cebu City, there is little clamor for modern mass transit systems. People tend to take commuting for granted with modes that they have grown up with like buses, jeepneys and tricycles until they start to experience first-hand the pains of traveling using inferior transport on severely congested roads. But even then, most seem to take it in stride and carry on, carrying their crosses in a state of purgatory that seems to have no end in sight.
