Automatic Signal Retiming Using Vehicular Trajectory Data
Traffic signal optimization is a cost-effective method for reducing congestion and energy consumption in urban areas. However, due to the high installation and maintenance costs of detection systems, most intersections are controlled by fixed-time traffic signals that rely on manual data collection and are not regularly optimized. More cost-effective methods for signal optimization need to be explored, such as the use of vehicle trajectory data that is now available. Research is needed to determine if this process can provide optimized timings at more frequent and regular intervals, yielding better overall signal performance.
