Abstract:

In order to solve the deficiency of the existing arterial signal coordination control methods based on double-cycle, Firstly, a new loop integer constraint suitable for double-cycle is derived. Secondly, the deficiencies of the existing methods are analyzed thoroughly. Thirdly, a double-cycle signal coordination model with maximizing the sum of weighting bi- directional progression bandwidths is established. Finally, taking Wangdao road in Yiwu city as an example, the VISSIM simulation software has been used to make contrastive analysis of advantages and disadvantages between the signal coordination plan generated by the established model and the signal timing plan generated by revised MULTIBAND model. The simulation results show that compared to the signal timing plan generated by revised MULTIBAND model, the signal coordination plan generated by the proposed model can efficiently decrease the average delay and stops in high, medium and low traffic demand, which indicates that the proposed model is effective and practicable.
