Signal Timing for Four-Phase Intersections Based on Efficiency Optimization
Abstract:
To utilize time-space resource of intersections efficiently, signal timing based on efficiency optimization was studied. The number of vehicles and speed were selected as two parameters constructing efficiency model for four-phase intersections, the relation model between these two parameters was developed basing on field data. The volume corresponding to optimal efficiency through derivation and signal timing on the basis of this volume were obtained by applying Synchro software. Conclusion through an actual case indicates that this method can achieve minimum delay on the premise of efficiency optimization and make the performance of signalized intersection better.
