Embodiment Construction

[0055] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0056] In order to effectively apply the model and method proposed by the present invention to solve practical problems such as generation, release and control of urban rail transit network dynamic accessibility, further steps can be carried out as follows:

[0057] (1) Development of dynamic accessibility calculation and simulation software for urban rail transit network. Considering the path search intensity caused by complex network results and the large amount of data to be processed, the network dynamic accessibility model and algorithm need to be realized by computer systems.

[0058] (2) Input relevant data of road network and operation. Including basic physical network information such as lines and stations, train operation information such as interval running time, stop time, and the time of the first and last train in each direction ...

Abstract

The invention discloses an urban mass transit network dynamic accessibility computing method based on time window constraints, which comprises the steps of network accessibility influence factor analysis, network accessibility analysis, last bus connection modeling, and flow calculation. An 'urban mass transit network dynamic accessibility analysis system' developed based on a model and algorithm disclosed by the invention is adopted for computing and emulating a first-last bus connection scheme among all the network stops. Contrast analysis on results shows that the model and algorithm disclosed by the invention have higher rationality and practicability. Computing result output is used for releasing dynamic and static accessibility information on the one hand, and on the other hand, passimeter controls such as preventing the last bus from the ticket-purchasing operations on the bus stops that the last bus stopped and preventing passengers from being incapable of arriving after purchasing tickets, and giving last bus time prompt for a target bus station and accessible path prompt when the passengers are purchasing tickets can be implemented; therefore, the intelligent level of passenger services is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of solving the dynamic accessibility evaluation of passengers traveling in an urban rail transit network and train operation connection. Background technique [0002] The urban rail transit system is a large-capacity, fast, punctual, and comfortable passenger transportation system. With the continuous expansion of the scale of the rail transit network in some cities in our country, the operation management has also entered the network operation stage accordingly. [0003] For passenger travel, the most notable feature of networked operation is the convenience of "one-ticket transfer". travel between stations. In order to meet the transfer needs of passengers during the travel process, the trains of each line should be reasonably connected at the transfer station, which is particularly important for the connection of the first and last trains of each line. When such a connection occurs on the first train, ...
