Problems solved by technology

Another important factor that affects the change of arrival time is the command and dispatch of BRT vehicles in the prior art. Only one scheme is adopted, that is, the same timetable is used for dispatch. When rainy and snowy weather occurs, resulting in slippery roads; or sudden foggy weather, resulting in reduced visibility, if the plan cannot be adjusted in real time, it will not be possible to ensure that BRT vehicles will operate accurately according to the timetable allowed by the current road speed limit. It is also impossible to accurately dispatch BRT vehicles

Embodiment 1

[0069] This embodiment provides a method for accurately dispatching BRT vehicles when an emergency occurs, such as Picture 1-1 with Figure 1-2 shown, including the following steps:

[0070] S1: Generate a planned schedule under different speed limit values, specifically including the following steps:

[0071] S11: According to different speed limit value V xi , use the BRT vehicles to drive along the BRT route at each speed limit value in actual operation in advance, and record the following driving data every second during the driving process under various speed limit values: BRT vehicles latitude and longitude information (X i ,Y i ), travel time T i , mileage S i , driving speed V i , and the stop time K at each stop j .

[0072] Among them, different speed limit values ​​correspond to the speed limit values ​​when some emergencies occur, such as sudden changes in weather and road conditions, which in turn have an impact on the speed limit value of the road. For ...

Embodiment 2

[0148] This embodiment provides a system for accurately dispatching BRT vehicles when an emergency occurs, such as figure 2 shown, including:

[0149] The first device is used to generate a planning schedule under different speed limit values, specifically including:

[0150] Data acquisition unit: according to different speed limit values ​​V xi , use the BRT vehicles to drive along the BRT route at each speed limit value in actual operation in advance, and record the following driving data every second during the driving process under various speed limit values: BRT vehicles latitude and longitude information (X i ,Y i ), travel time T i , mileage S i , driving speed V i , and the stop time K at each stop j .

[0151] Planned schedule generation unit: generate various speed limit values ​​V xi A plurality of planned timetables under each speed limit value records the starting station, passing station, and terminal station of the BRT route in the planned timetable c...

Abstract

The invention provides a method and a system for dispatching rapid buses accurately during emergencies. By means of the method and the system, when current speed limit is changed in case of emergency, rapid buses can be switched from execution time tables executed in the current speed limit condition to the corresponding speed limit execution time tables timely. Moreover, during the running of the rapid buses, real-time adjusting is performed on the execution time table corresponding to each speed limit constantly, so that all the execution time tables can be kept at the same reference position and reference time constantly, time and position errors when the different speed limit execution time tables of the rapid buses are switched can be prevented, and the rapid buses can be dispatched accurately at emergency time.

Description

technical field [0001] The invention relates to the technical field of rapid transit dispatching, in particular to a method and system for accurately dispatching rapid transit vehicles when an emergency occurs. Background technique [0002] Urban public transportation is one of the main means of transportation for people's daily travel in the city. It is an important part of ensuring people's basic living needs. Meeting people's growing travel needs and moving people from place A to place B in a safe, convenient, fast, punctual, comfortable and cheap manner is the goal pursued by decision makers at all levels of government. The emergence of BRT meets the needs of people to shorten the travel time. If the exact time of the BRT vehicle arriving at each station can be provided, the time for people to wait for a bus or transfer to other vehicles at the station can be shortened. [0003] In the daily operation of rapid public transport, one of the important factors for the inacc...
