Session 1: Tuesday, October 19 from Noon to 1:00 PM

Project Techniques and Treatments for using Big Data as a Travel Model

Presented by
Robert J. Watts, PE, PTOE, AICP
Transportation Engineer, McCormick Taylor

The COVID-19 pandemic presented traffic engineers with a variety of data collection challenges but also unveiled how “big data” could be used to meet some of those challenges. While this data can be used as a direct replacement for traffic counts and other studies, the various assumptions, potential biases, and sampling concerns built into it should be understood and addressed. We will present COVID adjustment techniques and estimations of other unique traffic conditions from two projects—the Lehigh Valley/MacArthur Road Signals Project and Laurel Valley Transportation Improvement Project. Both projects were advanced using data collected during the pandemic and incorporated data processing techniques that treat big data more as a “model” of travel, rather than a direct observation.

Session 2: Friday, October 22 from Noon to 1:00 PM
