Multi-Request Transit Signal Priority Control Model

In reality, several buses usually appear in each signal intersection entrance lanes at the same time. For this case, the paper try to study on multi-request priority decision methods and bus priority phase distribution. The purpose is to decrease the total per capita delay of priority request and improve buses' schedule adherence. For this study, the dynamic planning theory is introduced firstly and transit signal priority control problem is transformed into dynamic programming problem. Then the multi-request transit signal priority control model is established. The model is solved by the inverted sequence method of dynamic programming. Finally, an example is used to verify the model. The result of the experiment behaved rationally give credibility to the multi-applied transit signal priority model.
