Capacity and Road User Cost Analysis of Selected Freeway Work Zones in Texas

This research was developed to produce usable and meaningful estimates for work zone capacities under a variety of roadway and traffic conditions, work zone configurations, and lane closure scenarios within Texas. Using data collected at eighteen work zone sites, the research presents updated guidance for expected capacities of various freeway work zone lane closure configurations. In addition, models used to evaluate traffic conditions in work zones were evaluated and recommendations for their use were made. Finally, recommendations concerning road user cost analysis for freeway construction projects are included.
