Research on green light compensation model based on bus priority strategy

Aiming at the problem that the transit priority strategy may lead to the degradation of the level of service at intersections, this model firstly establishes a single-intersection transit priority request conflict model to solve the problem of sorting response to the priority request, in order to ensure that the transit vehicle with the highest sorting rank is given priority to pass through, so that the transit delay can be effectively reduced. Subsequently, on this basis, it is judged whether the intersection service level is greatly affected in the next cycle, and if it is greatly affected and needs to be restored, the phase is compensated for the green light through the intersection service level impact restoration model. Finally, the VISSIM simulation platform is used to verify the case, and the results show that the green light compensation model based on the bus active priority strategy can reduce the average social vehicle delay and the average bus delay, and improve the overall operational efficiency of the intersection.
