Problems solved by technology

[0003] The theory and method of coordinated dispatching of public transport and rail transit have achieved certain results at home and abroad, but there are still some shortcomings, mainly in the following aspects: less consideration is given to the carrying capacity of public transport, and it will There are stranded passengers, which leads to a certain deviation between the theoretical research and the actual situation; the fixed departure interval is used as the assumption or optimization goal, and the departure interval of the ground bus is often uncertain; The stop time of the station, and in practice, the stop time of the vehicle is a key factor affecting whether passengers can transfer successfully

Embodiment Construction

[0096] The technical solution of the present invention will be described in detail below: A bus dispatching method based on rail transit coordination mainly includes the following steps:

[0097] Step 1: Determine the rail transit station to be optimized, determine the research bus route and research time period;

[0098] Step 2: Collect the bus route data, rail transit data and other data to be optimized. The bus route data includes the free travel time of the vehicle from the origin to the transfer station, departure time, number of research vehicles, maximum departure interval, and minimum departure Interval, and the average arrival rate of non-transfer passengers; rail transit data includes train arrival time, the number of trains arriving, the number of people arriving at the bus station per train, the transfer time of passengers, and the research determined through sample surveys The transfer ratio of the bus line; other data includes the traffic volume between the bus origin...

Abstract

The invention discloses a bus dispatching method based on rail transit coordination, and the method comprises the following steps: determining an optimized rail transit stops and a bus line; collecting the selected bus line and the related data of rail transit traffic; dividing passengers waiting for buses at transfer stops into three classes according to the structure of a conventional bus passenger flow: random passengers, transfer passengers and detained passengers; calculating the waiting time of each class, and building a bus dispatching model with the shortest waiting time of passengers; designing an improved genetic algorithm, solving the model, and obtaining a departure time table of a bus; calculating the parking time and traveling time of the bus, and obtaining the departure time table of the bus. According to the invention, the method can improve the transfer efficiency of passengers, and improves the bus service level of the whole city.

Description

Technical field [0001] The invention belongs to the field of intelligent transportation systems, and in particular relates to a bus dispatching method based on rail transit coordination. Background technique [0002] In recent years, the construction of rail transit in big cities has accelerated significantly. As a large-capacity, safe, and environmentally friendly passenger transportation method, rail transit has played a very important and key role in solving urban problems with its unique advantages. However, because the overall capacity of the rail transit network will always reach the upper limit, it is impossible to build endlessly, and its service range can usually only cover both sides of the line. At this time, the ground public transportation needs to attract the passenger flow for the second time and extend its coverage. To every corner of the city. Therefore, it is particularly important to coordinate and optimize the timetable of ground public transportation based o...
