Introduction to Scientific Computing for Planners, Engineers, and Scientists
Liming Wang
Building on the successful scientific computing training program offered by the Software Carpentry (http://www.software-carpentry.org/), the proposed course exposes students in science, engineering, and planning to the best practices in scientific computing through hands-on lab sessions and aims to help students tackle the challenge of "drinking from a hose" when dealing with overwhelming amount of data that is increasingly common in these disciplines. Although computing is now an integral pa...

Using High-Resolution Bus Detection Data to Improve Travel Time Prediction and Identify Urban Congestion Spots
Miguel Andres Figliozzi
Robert Bertini
Transit travel time, operating speed and reliability all influence service attractiveness, operating cost and system efficiency. These metrics have a long-term impact on system effectiveness through a change in ridership. As part of its bus dispatch system (BDS), the Tri-County Metropolitan Transportation District of Oregon (TriMet) has been archiving automatic vehicle location (AVL) and automatic passenger count (APC) data for all bus trips at the stop level since 1997. In 2014, a new and hi...
