Transit Signal Priority Evaluation Model Based on Interval D-S Evidence Theory

Xu, Chun-yang / Chang, Yu-lin / Wang, Qi-peng

Striving to develop public transport is an effective way of alleviating traffic congestion in large and medium-sized cities, and arterial transit signal priority is an important measure for improving the reliability of bus operations. However, only few studies have evaluated the quality of arterial transit signal priority scenarios. To address this gap this article proposes a transit signal priority scheme evaluation model. First, an evaluation index for arterial transit signal priority is established. Second, a decisive model of interval D-S evidence theory for arterial transit signal priority is built. Finally, to address the uncertainty of the index attribute and the one-sidedness of a single decision maker, the advantages and disadvantages of the model are assessed on the basis of D-S evidence theory, and the optimal scheme is selected. This research provides a new theory and method for the transit signal priority scheme that can effectively avoid the one-sidedness of a single decision maker in evaluating transit signal priority and the uncertainty of index attributes, and provides technical support for extending the application of transit signal priority.
