Arterial Progression Signal Optimization for Speed Uncertainty Scenarios.

In order for the progression band to be effective, the convoy must travel at the fixed green band speed. However, due to the objective influence of uncertain factors, it's difficult for vehicles to drive at the green band speed, especially on the arterials, which have multiple important path flows in different directions. Due to the entanglement of path flows in different directions in the arterial segment, the operational interference between vehicles will increase. As a result, the speed of vehicles will inevitably fluctuate, which greatly weakens the control effect of arterial coordinated signal control methods. In order to improve the green bandwidth utilization efficiency, this paper proposes a multi-path arterial signal coordination control method that considers the speed uncertainty. The results of extensive simulation studies show that the proposed model outperforms other methods in terms of overall arterial performance, intersection performance and path performance. And the signal timing generated by the proposed model shows promise in reducing travel delays and stopping times, which indicates that it can achieve better multipath progression effect.
