Method of optimizing departure interval of multiple bus lines collaboratively with multi-objective model

Abstract

The invention discloses a method of optimizing a departure interval of multiple bus lines collaboratively with a multi-objective model. The method includes the three steps of collecting basic relevant information, dynamically scoring, and solving for a multi-objective model. In the optimizing process, maximizing operation profits of bus companies is met, and minimizing the passenger waiting time and passenger travel cost is also considered, the interests of the two aspects of the bus companies and passengers are maximally ensured to be optimal, and comprehensive collaborative optimization is performed from the points of view of both the system and users. Considering the multiple aspects from multiple angles and combined with actual bus operation characteristics, the method of the invention is highly practical, can provide theoretical support for decision-makers of bus organization and management, maximally ensures the interests of both bus companies and passengers, improves the satisfaction of the passengers with the bus, greatly improve the operating efficiency of multi-line buses, and has important practical significance.

Description

technical field [0001] The invention belongs to the field of urban multi-line public transport network organization, management and optimization, and relates to a multi-objective collaborative optimization method for bus departure interval optimization under the urban multi-line public transport network. Background technique [0002] At this stage, my country's huge urban traffic demand has formed a sharp contradiction with the overall relatively backward traffic system and traffic structure, and the problems of travel difficulties and traffic congestion are becoming more and more serious. Facing the increasingly prominent pressure of population, resource and environment contradictions, the relevant national policies also explicitly put forward the priority development of urban public transportation and improve the utilization efficiency of transportation resources. Priority intelligent management of urban public transport" has been listed as a priority theme, and the nation...

Problems solved by technology

[0004] After the inventor's long-term research, it has been found that at present, the bus departure interval establishment system in my country mainly compiles the timetable based on a single bus line, and determines its departure interval, and considers the connection and transfer between multiple bus lines, resulting in There is little coordination between lines, which is not conducive to the sharing of public transport resources. There is often a phenomenon of waiting for a long time when transferring, which has an adverse effect on the convenience and comfort of travel, and greatly reduces passenger satisfaction with public transport.

The method of determining the departure interval in the single-line operation mode is basically to analyze the passenger flow characteristics of a single line, and use statistical methods to calculate the departure interval. The calculation efficiency is low, and the revenue of the bus company is also low, and there is a lack of public transport from multiple lines. Coordinate the operation between lines from different perspectives, thereby reducing the overall service quality of public transport, reducing people's travel efficiency, and making the multi-line public transport network unable to exert its greatest advantages
