A tram priority control method considering the upper limit of vehicle delay increase in non-priority phases

Abstract

The invention provides a tram priority control method considering the non-priority phase social vehicle and public transport vehicle delay increase upper limit, belongs to the field of urban traffic control, and aims at enhancing passage efficiency of trams and reducing influence on social vehicles and public transport vehicles. The increment of total people delay of each phase of each intersection is reduced as far as possible by limiting the upper limit of delay of the passing social vehicles and the public transport vehicles of non-priority phases. Firstly delay of the trams at the intersection is reduced by adjusting speed of the trams. Then a green light extension or red light early break strategy is selected to be applied to each non-priority phase by limiting the upper limit of the increment of delay of the passing vehicle of the non-priority phases so that influence on the single non-priority phase can be reduced. Meanwhile, delay caused on the regular public transport vehicles is specially considered and the increment of total people delay of each non-priority phase of the intersection is reduced as far as possible. Operation efficiency of urban public traffic can be enhanced and the healthy development of urban traffic can also be facilitated.

Description

technical field [0001] The invention relates to a tram priority control method, which belongs to the field of urban traffic control. Background technique [0002] Tram is an efficient, convenient and fast urban public transportation mode that runs on the ground. However, due to the greater influence of road intersection signal control, the traffic efficiency and service quality of trams are relatively low. There is no technical solution to solve the relatively low traffic efficiency and service quality of trams in the prior art. [0003] It is an effective means to solve this problem to implement the measure of prioritization at intersections for trams. When implementing intersection priority control for trams, the problem of increased delays caused by non-priority phase passing social vehicles and buses should be considered to avoid excessive increase in non-priority phase delays, which embodies the concept of people-oriented.
