On the efficiency of transportation – a crash course on transportation engineering concepts

There is an excellent article on the efficiency of transportation systems:

Gleave, J. (2019) Space/Time and Transport Planning, Transport Futures, https://transportfutures.co/space-time-and-transport-planning-1aae891194e5 [Last accessed: February 25, 2019].

It is highly recommended not just for academics (including students) but also for anyone interested in transportation and traffic. It’s like a crash course in transportation engineering with a lot of basic concepts in traffic engineering and traffic flow theory being presented for easy understanding by anyone. Enjoy!

What happens now to the DOST’s AGTs?

The Automated Guideway Transit (AGT) vehicles that were used in the research and proof of concept at the previous test site in UP Diliman are scheduled to be transported back to DOST’s MIRDC soon. The vehicles are still in UP Diliman and are usable for R&D if someone decides to come up with a viable proposal for these. Unlike the hybrid electric train that is the AGT’s contemporary in terms of them being parallel projects, the future is unclear for both AGT models (i.e., there is another, higher capacity AGT already at MIRDC and tested using the test tracks there).

The two AGT vehicles are wrapped to protect them from the elements. These are functional and should still have value in case someone proposed to continue in their testing and refinement. It doesn’t need to be an elevated guideway for development to continue.

Here’s a closer look a colleague managed to take before we turned at the intersection.

What’s next for the AGT? Is there a future for these vehicles? Will the DOST initiate something with the DOTr or maybe with an LGU (Taguig?) to come up with a project that will employ these vehicles in what can be a full system instead of one on test tracks? Let’s hope these assets can still be utilised and not be wasted.

The AGT test site at UP Diliman is no more

This is actually a late post considering what has transpired last year that led to the demolition of the AGT test facilities at the University of the Philippines Diliman campus. For one, UP (or at least Diliman) didn’t want it. That was to be expected as Diliman’s Executive Council comprised of the constituent university’s deans and executive staff (Chancellor and Vice Chancellors) already stated that they don’t want an AGT in the campus many years ago and during the last administration when the main proponent, then DOST Secretary Montejo, was still very much in-charge of that department. Here are photos taken by a colleague last year showing the demolition work on the elevated guideway and stations. These were taken as they traveled along C.P. Garcia Avenue towards the University Avenue.

The demo was completed late last year and the AGT vehicle has been transferred to the MIRDC compound in Bicutan. The two prototypes are now there and there is an uncertainty about their futures. One colleague recalled “if only they had listened and had the AGT tested the proper way”. He was referring to the proposal to have an independent evaluation of the vehicle in order to ensure that its technical specifications and capabilities were up to international standards. The AGT proponents didn’t agree and proceeded according to what they wanted despite what we heard was a similar recommendation from then DOTC officials to have the vehicle certified as safe for public use.

I am happy to know that at least one project from that ambitious program during the last administration will finally be operational. A different approach seems to have been undertaken for the hybrid train that was produced for the PNR. Recent news stated that the train has undergone a series of tests and needs to hurdle a few more before going into operation along the PNR’s commuter line. Hopefully, it succeeds and encourage production of more like it and lead to an evolution of Philippine-made trains.

Article on induced demand and why more roads mean more traffic

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.

VannPashak, J. (2018) “More roads, same congestion,” http://www.medium.com, https://medium.com/@jvannpashak/more-roads-same-congestion-b2b437ecaa94 [Last accessed: 11/22/2018]

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.

Professorial Chair Colloquium of UP’s Institute of Civil Engineering

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:

On the need to increase NMT and public transport use

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:

Global Climate Report Calls For Expansion Of ‘Non-Motorized’ Transport And Public Transit (2018)

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:

25th Annual Conference of the Transportation Science Society of the Philippines

The Transportation Science Society of the Philippines (TSSP) will be holding its 25th Annual Conference in Cagayan De Oro City next week. Here is the program and you can get more details about the conference and the society from its homepage and Facebook page.
