摘要

This study presents a modified MULTIBAND model to address the defects of the conventional MULTIBAND model, the restricted solution scope due to the constraint of symmetric green-wave and the unstable green-wave performance due to improper location of green-wave within the whole green interval. The proposed model overcomes the constraint of the symmetric green-wave to acquire a more flexible green-wave and establishes another constraint on the green-wave location to allow the green-wave to be in the middle of the upstream/downstream green intervals as much as possible, the optimization model is modified accordingly. A simulation model based on the empirical data collected at 8 intersections along Yimeng road in the city of Linyi, China, is established to assess the performance of the proposed model. Results show that the proposed model is able to increase the total green-wave band width by 7.1%, and reduce the average delay and number of stops by 20.8% and 30.8% respectively, as compared with the conventional MULTIBAND model.
