Bus priority control system and method based on timetable

Abstract

The invention discloses a bus priority control system and a method based on a timetable. The bus priority control system comprises a vehicle identification unit, a timetable database unit, an intersection signal control unit and an intersection signal machine, wherein the vehicle identification unit obtains the information of a bus passing an intersection; bus lines passing the intersection and a preset running timetable are stored in the timetable database unit; and the intersection signal control unit obtains the information of the bus passing the intersection to compare with the running timetable in the timetable database unit, judges whether the bus is late, and executes vehicle priority control if the bus passing the intersection is late. The method solves the technical problem that whether the bus is late can not be judged in the condition that no GPS or wireless networks exist in the prior art. The method shortens the intersection passing time of the late bus, ensures that the late time of the bus at the next stop is reduced, and improves the on schedule rate of the bus.

Description

technical field [0001] The invention relates to a traffic signal control method in the field of intelligent traffic, in particular to a bus priority control method based on timetables. Background technique [0002] With the increase of urban population, road congestion and environmental pollution lead to a decline in the quality of life in the city. In order to improve energy utilization and improve environmental quality, the government advocates green travel and vigorously develops public transportation. Public transportation has become an important part of the field of intelligent transportation. bus schedule [0003] It is a regular and recurring driving plan formulated according to the flow law of urban public transport passengers, according to the quantity, direction and time of passenger flow. No matter from the perspective of passenger demand, vehicle operation or manager's scheduling, ensuring the punctual operation of buses can maximize the social benefits of the...

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that in the prior art, it is impossible to judge whether the bus is late without GPS or wireless network, thus proposing a method that can still judge whether the vehicle is late without GPS or wireless network. Timetable-based bus priority control method
