Here is a nice article about induced demand, which is simply the additional traffic you get on top of the current and estimated traffic from “normal” growth based on the current transportation system and infrastructure once you introduce additional services and/or infrastructure. That is, there is additional trips/traffic generated for when you widen roads or construct a new transit system.

I think the more interesting part of the article is its mention of the work of Redmond and Mokhtarian, which the author provides in a link. Clicking this link brings you to a wealth of articles attributed to the two that are definitely worth reading especially for people seeking understanding for issues related to commuting. Many of the researches and the methodologies in the articles may be replicated for application in the Philippines, and should be taken on as research topics in what can be inter-disciplinary programs or projects.
We start the month of November with an announcement. This is for the Professorial Chair Colloquium of the Institute of Civil Engineering of the University of the Philippines Diliman, which will be held on November 16, 2018 (Friday). The sessions are open to the public and surely there will be interesting topics not just regarding transportation but on the other fields as well. Following are information on the lecture topics:
A recent report reinforces what many of us already probably know or are aware of – that we need to shift away from dependence on car use to more sustainable modes of transport in the form of non-motorised transport (NMT) and public transportation. Here is the article from the AASHTO Journal:
There is a link to the report in the journal article. The report is conveniently available in PDF form and is very readable (i.e., not overly technical).
Incidentally, I was involved some time ago in a project led by the group Clean Air Asia (CAA), which involved several experts from across ASEAN as well as Japan that attempted to determine the necessary transport programs and projects in the region to stave off the projected increase in global temperatures. In all the scenarios evaluated, non-motorised transport (NMT) and a rationalised public transportation system By the term ‘rationalised’ I am referring to the use of higher capacity vehicles as against the taxis and tricycles that typically carry few if not one passenger. Here is a link to the final symposium for that study that has links to the materials presented:
Here’s a slightly updated slide on the future image for a large city in the Philippines:
My students have been engaged in studies on walkability (and related topics) the past few years. These have been a mix of published and unpublished work that I have compiled at list below:

Here’s a paper based on a comprehensive study our centre conducted for the City of Olongapo in the Province of Zambales:

We hope to continue such studies with future advisees who perhaps can tackle other corridors or even areas. Among those on my Wishlist would be Espana Avenue, Ortigas Avenue, Intramuros, Recto Avenue, and even EDSA or Circumferential Road 5.
Our staff were implementing surveys in relation to the proposed railway projects supported by the Government of Japan. They came across this scene showing the DOST’s (through its MIRDC) hybrid electric train.
The hybrid electric train at the PNR Calamba Station. It looks like its being maintained or checked although I’m not sure the crude set-up is appropriate for such undertaking.
The DOST had a much hyped program during the last administration about the development of Philippine-made transport. Among these were the two Automated Guideway Transport (AGT) train sets that were developed by the MIRDC – one with two 60-passenger (seated and standing) cars and a test track in UP Diliman, and another with two 120-passenger cars with test track at the MIRD compound in Bicutan. While both had what were claimed as extensive tests, these were mainly done by DOST/MIRDC personnel with no independent inspections or validations. At one time, I recall that we at UP had discussions with representatives of Mitsubishi Heavy Industries who offered to explore arranging for a technical cooperation project to have a full-scale testing of the AGT’s using their facilities in Japan. We referred them to MIRDC and that didn’t turn out well as the agency (or perhaps under the the instructions of a higher official?) was supposed to have rejected the offer preferring it to be tested locally. That was a major problem because there were no suitable testing facilities or qualified persons or institutions to grant certification for the AGT to be used as public transport.
The last time I checked with folks at DOST and UP, the AGT prototype set-up in Diliman was already being scheduled for dismantling. This probably comes as a welcome development for those who opposed the project from the start. However, there is potential here for continuing research if only funding could be secured and proponents kept open minds and objectivity in the way researches could be done. There was the perception before that the people behind the AGT projects were so engrossed with what they thought were their babies that they blocked critical but objective comments and recommendations about the prototypes and their applications.
As for the hybrid electric train, there is now supposed to be a cooperative project between the MIRDC and PNR. I recall a few months ago that they even had some test runs to show the hybrid train to be running on PNR tracks; even hyping that this could be part of the future of a rehabilitated PNR. Is this true or just PR? Hopefully, the DOST could get the context right, and the DOTr and PNR can support such initiatives for Philippine-made transport. This is especially as the current administration continues to pursue its Build, Build, Build program that has as major features several railway projects.
I would like to promote a symposium that our Institute of Civil Engineering (ICE) at the University of the Philippines Diliman will be hosting this year.
