Real-time queue length perception with green wave band point optimization based on floating vehicle

With the development of satellite positioning technology and network communication technology, the floating vehicle data has the advantages of large amount of data, high precision and wide Coverage. In order to improve the green wave control effect, combines the floating vehicle trajectory data with distributed wave theory, makes the real-time prediction of queue length of current cycle and the time of complete disappearance, and analyzes the green-start coordination, green-middle coordination and green-end coordination in the advantages and disadvantages, designs an optimal control strategy with dynamic green point floating vehicle queue length based on real-time sensing green, improves the efficiency of green band, through simulation experiments to prove the effectiveness of the proposed method.
