Regional multimodal rail transit passenger flow dynamic allocation method under operation interruption condition

Abstract

The invention discloses a regional multimodal rail transit passenger flow dynamic allocation method under an operation interruption condition. The method comprises the following steps: 1, constructinga regional multimodal rail transit timetable extension network; 2, constructing a multi-system rail transit network passenger flow distribution model; and 3, under the condition of operation interruption, solving the multi-standard rail transit network passenger flow distribution model by utilizing station and interval numbers, interruption accident duration and driving measures for maintaining operation after interruption contained in an interruption interval, and finally obtaining the passenger flow distribution quantity of each OD for passenger flow based on an effective path and corresponding indexes thereof. The model constructed by the invention can better describe the actual situation distribution situation of passengers in each path; on the basis of the operation interruption condition, various transportation modes can be compatible, and emergency cooperative management among the multimodal rail transit is facilitated; real-time travel tracks and distribution conditions of passengers can be described more accurately and effectively, and theoretical support and guidance are provided for emergency passenger flow distribution of multi-type rail transit.

Description

technical field [0001] The invention relates to a method for dynamically allocating passengers of regional multimodal rail transit under the condition of operation interruption. Background technique [0002] The future regional rail transit of urban agglomerations in my country is a comprehensive network rail transit system that coordinates the development of various rail transit modes. There is no strict definition of regional rail transit, and it is generally considered to include three levels: Urban rail that mainly undertakes travel needs in urban centers Transportation: Suburban railways that mainly undertake the passenger transportation needs of the suburbs and central urban areas; intercity and trunk railways that mainly undertake the passenger transportation needs between cities. During the transformation of regional rail transit from single-system relatively independent operation management to multi-system networked comprehensive operation management, due to the diff...

Problems solved by technology

During the transformation of regional rail transit from single-system relatively independent operation management to multi-system networked comprehensive operation management, due to the differences in functional positioning, passenger flow, main technical standards and service objects of various rail transit systems, the scale of the network Increasing complexity, diversification of networked transportation organization methods, increasing types and scale of maintenance system equipment, increasing difficulty in passenger flow management, leading to an increase in unstable factors affecting operational safety

[0003] At the same time, with the changes in the rail transit network structure and the diversification of travel modes, networked operations will inevitably bring about intersection and parallelization between lines, which will also bring about a large number of transfers between various systems of rail transit , the transfer flow of passengers between different systems in the form of regional rail transit network, choose different travel modes, transfer points and travel routes, the utility brought to travelers is not the same, and the mutual influence between various modes, giving Multi-mode transportation network operation brings many uncertainties
