Decision Support Tool for Nighttime Construction and Air Quality - User's Guide

The Texas Department of Transportation (TxDOT) Research Project 0-6864 Investigate the Air Quality Benefits of Nighttime Construction in Non-attainment Counties investigated the potential air quality benefits of shifting construction/maintenance activities to the nighttime. A decision-support framework in the form of a spreadsheet tool was developed as part of this study to put the findings on the air quality benefits into the broader context of decision making for nighttime construction. The framework is developed to help TxDOT make systematic decisions on whether a project is suited for nighttime construction activity, taking into account numerous factors including potential air quality benefits.
