Abstract

The invention discloses a system and method for improving bus rapid transit dispatch precision and belongs to the field of intelligent transportation applied technologies. A bus rapid transit vehicle is used for driving one time in advance according to a bus rapid transit line, wherein the bus rapid transit vehicle is provided with a vehicle-mounted GPS positioning unit and a vehicle-mounted mileage counting unit. Position information determined by the vehicle-mounted GPS positioning unit and the vehicle-mounted mileage counting unit at every second serves as reference positions, and in the process of driving, the position information detected by the direct adoption of a GPS positioning sub-module serves as actual position information of the vehicle. When the vehicle is driven under a tunnel, a flyover and the like, a GPS signal is sheltered and position data can not be output, the system determines the current position of the vehicle through the mileage counting sub-module, so that bus rapid transit is corrected to seconds per second, and the situation that issued arrival information is corrected to seconds is further guaranteed.

Description

technical field [0001] The invention relates to the field of rapid transit dispatching, in particular to a system and method for improving dispatching accuracy of rapid transit. Background technique [0002] Urban road traffic is the "blood vessel" of the city, and making it smooth is the guarantee for the sustainable development of the city. At present, the supply of urban road traffic is far from meeting the traffic demand, resulting in urban road traffic congestion. The causes of urban traffic congestion are multi-faceted. How to improve the efficiency of public transportation to meet traffic demand and alleviate traffic congestion is one of the main issues that traffic management decision-makers care about. [0003] Traffic demand refers to the requirements for people and things to move in various ways in social public space for various purposes. Therefore, it is the pursuit of traffic management decision makers to use transportation means with large passenger capacity...
