60021-3 Report Abstract

Workzone Mobile Source Emission Prediction

Pattabiraman Seshadri and Rob Harrison, University of Texas at Austin, May 1993, 138 pp.

The traffic congestion that results from freeway reconstruction and rehabilitation work often leads to an increase in vehicle emissions within the construction workzone. In this report, the authors develop a methodology for calculating these excess emissions. This methodology, presented in the form of a computer model, takes into account workzone configuration and traffic characteristics. Using the model, planners can compare different workzone strategies to identify the one that most effectively reduces vehicle emissions.
