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,”, [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 other uses of ridesharing/ ridehailing services

We start 2018 with another article that I found this interesting. The article is on the other uses of ridesharing, particularly for medical emergencies:

Seipel, T. (2017) “Uber reduces ambulance usage across the country, study says”. (Last accessed: 12/22/2017).

This article was particularly interesting to me because we are currently doing research on ridesharing. This should be a good topic for students who are looking for something current and relevant, and should fit well in the bigger scheme of things in as far as our research agenda is concerned. There is a link to the study report in the article for those wanting to get the details on the outcomes.

Some recommended references for sustainable transportation design

We conclude the month of October with the following recommended readings:

While these are guidelines and manuals developed and published in the United States, the principles and much of the content and context are very much applicable here.

As an additional reference, here is the latest version of functional classifications for streets that is supposed to be context-sensitive:

New study on ride-hailing

Here’s a nice article that has a link to a study conducted at the University of California-Davis written by one of the authors of the study:

Clewlow, R.R. (2017) “New Research on How Ride-Hailing Impacts Travel Behavior” in Planetizen, October 11, 2017.

And here’s an article about that same study:

Bliss, L. (2017) “The Ride-Hailing Effect: More Cars, More Trips, More Miles ” in Citylab, October 12, 2017.

As usual, I am posting this for reference not just for my readers but for myself and my students who are currently doing research on ridesharing/ride-hailing in the Philippines.
