The Gwinnett Place area traffic system consists of 57 signalized intersections with primary corridors including Pleasant Hill Road, Satellite Boulevard, Steve Reynolds Boulevard and Club Drive. The Gwinnett Place system also includes two interchanges with I-85, a half diamond at Steve Reynolds Boulevard and a DDI at Pleasant Hill Road. Pleasant Hill Road maintains heavy volumes throughout the day with additional commuter travel during the peaks. Satellite Boulevard includes 14 intersections and is parallel to I-85. It is a popular alternate route to I-85 with heavy peaks in the morning and afternoon. Steve Reynolds Boulevard, combined with Club Drive, is a popular alternative route to Pleasant Hill Road as it circumvents some of the congestion surrounding Gwinnett Place Mall.
Traffic Responsive Signal control systems (TRS) are useful in areas with heavy traffic volumes and unpredictable traffic patterns. The system reacts to changes in traffic demand and then implements timing plans most suited for the traffic conditions. It works well along popular alternative or bypass routes that are impacted by weather, incidents, seasonal variations or planned special events. The Gwinnett Place system is an ideal location for a TR system because of the heavy and often variable volumes along Pleasant Hill Road, alternate route options for I-85 and Pleasant Hill Road, and volume variation on weekends due to traffic generated by area retail. The goal for the Gwinnett Place TR system is to run the most suitable traffic control patterns based on traffic volumes.
