Embodiment Construction

[0022] A service network design method including regional multi-system rail transit, the present invention will be described in detail below in conjunction with the accompanying drawings, such as figure 1 As shown, this method mainly includes two parts, the construction of the service network and the construction of the dynamic service network model, including the following contents:

[0023] 1. Service network construction stage

[0024] The present invention aims to optimize the design of the regional rail transit dynamic service network during peak hours, and the present invention will be described below by taking five rail transit stations as examples. Such as figure 2 As shown, A, B, C, D, and E all represent rail transit stations, and trains between two points only run between the two points, and there is no cross-line operation. Consider a variety of transportation methods, including subways and other rail transportation methods other than subways (for example: inter...

Abstract

The invention discloses a dynamic service network optimization design method for multi-standard regional rail transit. The method comprises the steps of constructing a regional rail transit dynamic service network in a peak period and constructing a regional rail transit dynamic service network model: step 1, establishing an objective function taking passenger generalized travel cost minimizationas an objective; and step 2, determining the following constraint conditions: capacity constraint, flow conservation constraint, minimum departure interval constraint and decision variable logic constraint. Compared with the prior art, the method has the positive effects that at the peak transportation moment, the real-time passenger transportation requirement can be met as much as possible, the passenger on-way time is shortened, the passenger travel track is accurately described, and urban congestion is properly relieved; various transportation modes can be compatible, collaborative optimization is achieved, and inter-regional train running is more reasonable; the nonlinear departure is represented through linear constraint, so that the solving difficulty of the method is reduced; and algorithm programming is not needed, and the solving speed is higher by using corresponding solving software.

Description

technical field [0001] The invention relates to a dynamic service network optimization design method for multi-standard regional rail transit. Background technique [0002] Regional rail transit is an important part of the comprehensive regional transportation system and the "backbone" and "blood" of a city. Regional rail transit mainly includes urban rail transit for urban center travel, suburban railways for suburban and downtown passenger transport, and intercity and trunk railways for transportation between urban agglomerations. The quality of the train service network design, which includes the operation plan and operation time, directly determines the quality of rail transit operation service. Among them, the static service network design is mainly to solve the problem of optimal allocation of transportation resources, and the dynamic service network can solve more time-sensitive problems because of the time factor, so the high-quality regional rail transit dynamic se...
