Actuated signal control (ASC) works based on vehicle actuations that utilize vehicle headway or count for signal control. However, under mixed traffic conditions, it is nearly impossible to obtain such data from all the vehicles in the traffic stream. Under such scenarios, the average delay of vehicles obtained from a representative sample of vehicles can be used as an input for signal control. This study evaluated the effectiveness of RFID sensors for real-time delay estimation where the average approach delay obtained from RFID sensors was used as the control variable for the working of an actuated signal control system at an isolated intersection. Based on the simulation results, it was observed that a penetration rate of 80% of total car volume in the traffic stream would effectively represent a vehicle actuated system that works based on delay from all vehicles in the traffic stream along with better performance in terms of percentage reduction in overall intersection delay.
