Embodiment Construction

[0041] The technical solution of the present invention will be further described below in conjunction with the drawings and embodiments.

[0042] (1) Divide the service area into n blocks, and each block is set as a square with the acceptable walking distance of passengers as the side length. Generally, 100m is the acceptable walking distance of passengers. The number of endpoints in each block. It is required that the passenger needs of each time period are met by the same bus.

[0043] (2) According to the statistics of the number of passenger start or end points in each block in all periods of time according to step (1), the blocks are rearranged from large to small, and the distance between stations is fixed between the upper and lower limits. The upper and lower limits are set at 1000m-3000m, and the vehicle running speed along the baseline shall not be lower than the minimum speed as the control condition. It is determined in order whether all blocks can be set as fixed stat...

Abstract

The invention provides a method for determining fixed stations and dynamic stations of a variable-route bus, and the method comprises the following steps: dividing a service region into blocks, and carrying out the statistics of the traffic demands of passengers in the blocks; determining a fixed station and a to-be-selected dynamic station according to the passenger traffic demand and a certain limiting condition; and establishing an objective function by taking the minimum weighted sum of the passenger travel cost and the bus operation cost as a target, and searching by adopting a genetic algorithm to obtain the optimal dynamic station of each time period. According to the method, the minimum weighted sum of the passenger travel cost and the bus operation cost is taken as a target, and position planning of fixed stations and dynamic stations is carried out. And the bus operation cost is considered under the condition that the travel service quality of most passengers is improved. Themethod is high in adaptability and has high application value.

Description

Technical field [0001] The invention relates to a method for determining a variable line type public transportation fixed station and a dynamic station, and belongs to the technical field of traffic operation and dispatching. Background technique [0002] As a new type of public transportation service, variable-route public transportation can greatly increase the flexibility of public transportation operations, and transform ground public transportation and rapid public transportation from a competitive relationship to a complementary relationship, thereby improving the overall service level of public transportation and inspiring ground transportation Development vitality. [0003] The variable route bus can be described as: the vehicle travels along a fixed route in a certain service area, stops at a fixed station, and under certain conditions, stops at a dynamic station other than the fixed line according to the actual needs of passengers, if there is no other passenger demand ,...
