Embodiment Construction

[0022] A service network design method including regional multi-standard rail transit, the present invention is described in detail below with reference to 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. The present invention is described below by taking five rail transit stations as examples. like figure 2 As shown, A, B, C, D, and E all represent rail transit stations, and the trains between two points only run between the two points, and there is no case of running across the line. Consider multiple modes of transportation, including subways and other rail modes other than subways (eg, intercity railways, urban railways, ...

Abstract

The invention discloses a dynamic service network optimization design method for multi-system regional rail transit, including constructing a regional rail transit dynamic service network during peak hours and constructing a regional rail transit dynamic service network model: step 1, establishing a generalized travel cost for passengers The minimum is the objective function of the objective; Step 2, determine the following constraints: capacity constraints, flow conservation constraints, minimum departure interval constraints and logic constraints of decision variables. Compared with the prior art, the positive effects of the present invention are: during peak transportation hours, real-time passenger transportation needs can be met as much as possible, passenger travel time can be reduced, passenger travel trajectories can be accurately described, and urban congestion can be appropriately alleviated; it can be compatible with various transportation The method and collaborative optimization make inter-regional trains more reasonable; the nonlinear departure is represented by linear constraints, which reduces the difficulty of solving this method; and does not require algorithm programming, and the solution speed is faster when 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 it is the "backbone" and "blood" of the city. Regional rail transit mainly includes urban rail transit for travel in urban centers, suburban railways for passenger transport needs in suburban and downtown areas, and intercity and trunk railways for transportation between urban agglomerations. The quality of the train service network design, which includes the running plan and the running time, directly determines the quality of rail transit operation services. Among them, the static service network design is mainly to solve the problem of optimal allocation of transportation resources, while the dynamic service network can solve more time-sensitive problems because of the consideration of time factors. The...
