Method for selecting and adjusting conventional bus routes along rail transit

Abstract

The invention relates to a method for selecting and adjusting a conventional bus route along a rail transit line. The method specifically comprises a method for selecting a conventional bus route to be adjusted along a rail transit line based on a generalized travel time cost and travel time saving proportion model. According to the method, a common line segment generalized travel time cost and travel time saving proportion model of conventional buses and rail transit is constructed. The time effectiveness of the common line segment of the rail transit relative to the conventional buses is evaluated, and to-be-adjusted conventional bus lines are screened out. The invention discloses an endpoint line adjustment method based on a station importance mean value and a unilateral confidence interval. Station importance is calculated on the basis of conventional bus line transfer passenger flow. Whether an endpoint line is an important line or not is evaluated, and whether an important station exists in a non-important endpoint line or not is evaluated at a certain confidence level. An adjustment principle of the endpoint line is formulated by combining the length of the endpoint line. According to the invention, coordinated development of rail transit and conventional buses can be promoted, and a basis is provided for urban public transit development decisions.

Description

technical field [0001] The invention relates to the technical fields of smart city and intelligent transportation, urban traffic planning, big data analysis and excavation and comprehensive application, in particular to a method for selecting and adjusting conventional bus routes along rail transit lines. Background technique [0002] Rail transit occupies a dominant position in the urban public transportation system with the advantages of large transport volume, fast speed, and high punctuality rate. Since rail transit needs to carry the main flow direction of urban passenger flow, the route direction is usually the same as that of conventional bus lines. To coincide. After the opening of the rail transit, it often causes the transfer of conventional bus passenger flow along the line. In order to make it play a role in large capacity and avoid a certain degree of waste of conventional bus capacity, it is necessary to optimize and adjust the conventional bus lines along the ...

Problems solved by technology

The adjustments of conventional bus lines along the track studied by domestic scholars are all after the track is put into operation, only fixed indicators (collinear length 6.75km) that affect the adjustment of conventional bus lines are used to determine the bus lines to be adjusted, and cities use unified indicators in practice The empirical value of the collinear line above 6Km does not take into account the effect of rail transit relative to the conventional bus lines along the line for targeted adjustments

In terms of optimization of conventional bus lines along rail transit lines, domestic and foreign only focus on the coordinated operation of conventional buses and rail transit, optimize the station spacing and operating parameters of conventional buses, and optimize the entire network. The research on the adjustment of conventional bus lines only Judging by experience, the passenger flow distribution and transfer characteristics of conventional bus lines are not considered; The utility of the line segment track relative to the conventional bus is related to the spatial relationship of the stations
