摘要

This project was conducted to investigate new concepts, new tools and emerging technologies directed at enhancing traffic operations and safety on signalized urban arterials that operate under saturated conditions. McFarland Boulevard, a six-lane urban arterial running north-south through Tuscaloosa, AL served as the research focus and test bed for the project. There are nine urban intersections along the study route, with a variety of configurations, turning movements and traffic volumes. In a unique approach, this project was conducted as three related and parallel efforts by the three participating UTCA universities. UAH investigated the feasibility of using video data for determining control delay on the approach to signalized intersections, and used the results to investigate the accuracy of delay predictions by popular simulation models. UAB investigated use of VISTA as a simulation model for saturated arterial traffic flow analysis. UA investigated methods to optimize traffic flow at saturated intersections through enhanced simulation models.
