Problems solved by technology

[0004] However, the needs of passengers are constantly changing, and the departure interval calculated by the existing method based on a certain moment is not optimal at other times, so there is still a lot of room for improvement in the efficiency of the entire bus system

Embodiment example

[0139] Select 15 consecutive stations of a bus line in Nanjing City, Jiangsu Province, and the departure interval of buses is 10 minutes, that is, 600s. Through a large number of investigations, and using the gray prediction GM (1,1) to predict the actual running time and planned running time of buses between two adjacent stations, as shown in Table 1:

[0140] Table 1 The actual time and planning time of vehicles running between stations

[0141]

[0142]

[0143] The number of people getting on and off at each station is predicted by GM(1,1) in a certain period of time, as shown in Table 2:

[0144] Table 2 The number of passengers getting on and off the vehicle at each station

[0145]

[0146]

[0147] Calculate the stopping time of vehicles at various stations

[0148] t st= t oc +max{t i ×PO,t 0 ×PI}

[0149] Through a large amount of data investigation, the t oc Take the average value of t oc = 5s. for t i and t 0 , also through a large amount of...

Abstract

The invention discloses a public transportation vehicle station-skipping scheduling method and system. With the public transportation vehicle station-skipping scheduling method adopted, station-skipping driving can be possibly realized in the operating process of public transportation vehicles since no passengers get off the vehicles or no passengers get on the vehicles in stations, or in order to ensure the punctuality of public transportation. According to the public transportation vehicle station-skipping scheduling method, based on passenger get-off information obtained in the vehicles and passenger get-on need information in the stations, and the number of waiting passengers and the number of passengers who get off the vehicles in each period, in each station and on each line as well as difference values of actual time and scheduled time of the operating of the vehicles between any two adjacent stations in each period are predicted according to a large amount of historical route operating data, and whether station-skipping scheduling is carried out or not can be judged according to defined passenger punctuality deviation values. With the public transportation vehicle station-skipping scheduling method and system of the invention adopted, the service level of urban public transportation and the punctuality rate of the public transportation can be improved, and the competitiveness of the public transportation can be improved.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, in particular to a control method and system for over-stop dispatching of public transport vehicles. Background technique [0002] During the operation of urban public transportation, many factors cause the operation of public transportation to deviate from the preset timetable. With the continuous improvement of users' requirements on the level of public transport services, the punctual rate of buses arriving at various stations and the time passengers wait for buses have become important indicators to measure the level of urban public transport services and development. [0003] Existing control strategies include reservation dispatching, express dispatching and other methods. Among them, over-stop dispatching is also called "express train dispatching", that is, vehicles pass over some stations during operation (without stopping), avoiding related stop time, and thus improving operati...
