Example Embodiment

[0033] Example 1:

[0034] The bus priority control system based on schedule of the present invention comprises:

[0035] Vehicle identification unit: including the vehicle sensing device and time module installed in front of the stop line at the intersection, to obtain the line information and passing time of the bus to and from the bus, and transmit the obtained information. The vehicle sensing device here is a vehicle detector, which is arranged 50 meters before the stop line at the intersection. Detectable coded information is set on the passing bus, and the coded information includes the route information of the bus. The vehicle detector can detect the arrival of the bus, and read the coded information on the bus at the same time to obtain its route information . Simultaneously described time module can record the time when bus arrives.

[0036] Timetable database unit: comprising a timetable database, which records the bus lines and preset passing timetables passing...

Example Embodiment

[0044] Example 2:

[0045] On the basis of the foregoing embodiments, the control method of the timetable-based bus priority control system may also include the following process:

[0046] In the step (2), when the delay judging module judges whether the bus is late, the following situations are included:

[0047] A. If the passing time of the bus is within 1 minute later than the running timetable, it will not be judged as late.

[0048] B. When a bus on the same bus line arrives at the intersection again within 3 minutes after the vehicle priority control is executed, the delay judging module does not consider the bus to be late.

[0049] C. From the time when vehicle priority control is executed to the preset next shift time in the transit time table corresponding to the bus line, the vehicle arriving between the time, the delay judging module judges that the bus of the next shift arrives ahead of schedule, Don't think the bus is late.

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...
