Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] like figure 1 Shown is an application framework of an urban rail transit timetable optimization technology, and the present invention will be further described below in conjunction with examples.

[0045] Module1: passenger flow data extraction and preprocessing module

[0046] It is advisable to select the complete passenger transaction records of Nanjing Metro Line 1 collected by the Nanjing Metro AFC system on a certain working day in history as the module input, and follow the steps below to extract the valid passenger transaction information required in the subsequent link:

[0047] ① Extract all outbound transaction records according to the transaction type keywords for use;

[0048] ② All outbound transaction records are distributed upstream and downstream according to the OD vector direction between stations;

[0049] ③ Prepare data processing program...

Abstract

The invention discloses an urban railway transit timetable optimizing technology application framework. The urban railway transit timetable optimizing technology application framework comprises a passenger flow data extraction and preprocessing module 1, an interstation passenger flow distributive-law extraction module 2, a platform passenger arrival rate extraction module 3, a dispatch model establishment and analysis module 4 and an optimization result output and verification module 5. The module 1 is in charge of extracting available passenger transaction information from original passenger flow data for use in follow-up links; the module 2 and the module 3 are in charge of extracting passenger-flow characteristic parameters significant to later modeling; the module 4 serves as the core of the framework and is capable of establishing a dispatch optimization model and solving on the basis of the passenger-flow characteristic parameters; the module 5 is mainly used for converting optimization results into corresponding train timetables. The urban railway transit timetable optimizing technology application framework is used for optimizing and adjusting current departure timetables of urban railway transit lines, and can be combined with the short-term passenger flow forecasting technology for providing technique support for working out a train optional dispatch plan within a given future period.

Description

technical field [0001] The invention relates to an application framework of urban rail transit timetable optimization technology, which belongs to the intelligent technology of urban rail transit. Background technique [0002] With the rapid development of urban rail transit, the road network structure is becoming more and more complex, and the passenger flow is increasing. Whether the urban rail transit system can operate normally and efficiently depends not only on the infrastructure conditions such as rails and vehicles, but also on the advanced nature of operation management and its technical means. As the core of rail transit operation management and the link between passengers and operating companies, train timetable optimization technology research is increasingly valued. [0003] Urban rail transit belongs to the category of urban public transportation, which is quite similar to road public transportation. Therefore, scholars at home and abroad usually use the rese...
