Abstract
This report summarizes the improved data base and analysis tools developed as part of Study 1108 for analyzing the travel impacts of freeway maintenance and reconstruction activities. The data base includes the travel impacts of 12 urban freeway reconstruction projects (six in Texas and six outside Texas), the safety impacts of 5 urban freeway reconstruction projects in Texas, the traffic-handling capacities of 33 short-term freeway work zone lane closures, and the diversion characteristics at 11 short-term freeway work zone closures. The analysis tools developed include new procedures for estimating short-term freeway work zone lane closure capacity and a new version of the QUEWZ model named QUEWZ-92.
