Abstract

The invention discloses a system and method using windscreen projection to increase accuracy of bus rapid transit scheduling, and belongs to the technical field of intelligent transportation application. The method includes the steps of enabling a bus rapid transit vehicle provided with a vehicle-mounted GPS positioning unit and a vehicle-mounted mileage counting unit to run one time in advance according to a bus rapid transit route, using position information determined per second by the vehicle-mounted GPS positioning unit and the vehicle-mounted mileage counting unit as a benchmark position, and directly utilizing vehicle position information detected by a GPS positioning sub-module as vehicle actual positional information in the running process. When position data can not be output under the conditions that the vehicle runs below a tunnel, an overpass and the like due to the fact that vehicle GPS signals are sheltered, the system can determine the current position of the vehicle according to data of a mileage counting sub-module. Therefore, the system and method can ensure the running position of the bus rapid transit to be accurate to seconds and further ensure the issued arriving information to be accurate to seconds.

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 by utilizing windshield projection. 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 ...
