A Revised MULTIBAND Model for Arterial Road Coordinate Control

Abstract:

This study proposed a revised MULTIBAND model to address the existing problems of the conventional MULTIBAND model, which are restricted solution scope due to the constraint of symmetric green-wave and unstable green-wave performance due to improper location of green-wave within the whole green interval at each intersection. The proposed model removes the constraint of symmetric green-wave to acquire more flexibility of the green-wave, adds another constraint on the green-wave location letting the green-wave as far as possible in the middle of upstream/downstream green interval, and meanwhile modifies the optimization model accordingly. A simulation model based on the empirical data collected at 8 intersections along Yimeng road in the city of Linyi, China, was established to assess the performance of the proposed model. The results showed that the proposed model is able to increase the total green-wave band width by 7.1% and reduce the average delay by 20.8% and number of stops by 30.8% respectively, as compared with the conventional MULTIBAND model.
