摘要
A new coordinated control model was proposed aiming to solve the problems of the heavy traffic congestion on the bottleneck of freeway, the increase of total delay and the decline of the traffic efficiency, etc. The congested degree indexes were formulated based on the analysis of main characters of the traffic operation and congestion in freeway mainline bottleneck zone. The foundation of congestion degree indexes was the queue length of the freeway bottleneck zone upstream mainline and ramp. The coordinated control model was proposed considering the priority for vehicles on the ramp and the mainline of bottleneck zone upstream. The coordinated control method aimed to improve the traffic volume and the average travel speed. The effectiveness of the coordinated control model was verified by the contrastive analysis of three control cases. Results show that the proposed coordinated control model can effectively improve the maximum traffic capability. Compared with the cases of no control and mainline control, the maximum traffic capability was enhanced by 5.04% and 4.09%, respectively. ©, 2015, Zhejiang University. All right reserved.
