Safety and Operational Evaluation of Adaptive Signal Control

项目名称：	Safety and Operational Evaluation of Adaptive Signal Control
摘要：	The objective of this project is to perform an operational and safety evaluation of three adaptive signal control deployments (Birmingham, Huntsville, and Montgomery) in Alabama. Specifically, the project will document changes in operational performance measures (delay, travel time, number of stops, etc.). The project will comprise detailed analyses of traffic operations at all signalized intersections along the study corridors and unsignalized intersections at major midblock traffic source/sinks (as agreed with the Alabama Department of Transportation) for existing peak-hour traffic conditions and for similar peak-hour conditions after implementation of adaptive control. The analyses will be conducted using the VISSIM traffic-simulation software and travel time runs conducted along the three corridors. In addition, we will conduct a detailed review of the safety performance attributable to the implementation of adaptive signal control. We will compare three years of crash data from these corridors before implementation of adaptive signal control to three years of data we collect after implementation of adaptive signal control. If feasible, crash modification factors will be developed for future use, and the project will investigate the use of the Surrogate Safety Assessment Model to predict the safety impacts of adaptive control.
