自然语言表示的特定径路规则下铁路网车流径路计算方法研究
Calculation Methods for Traffic Routes in Railway Networks under Specific Route Rules Represented in Natural Language
摘要
Abstract
Railway traffic routes comprise shortest routes and specific routes,with the latter represented by semi-structured natural language text.Research on the calculation methods for traffic routes under such specific route rules is of great significance for enabling intelligent traffic route management.This paper first analyzed the forms of representation and the components of specific routes.Then,it established regular expressions to extract specific route information,converting origin/destination domains,via-paths,and special lines into sets of stations,mandatory station sequences,and sets of prohibited segments,respectively.Based on shortest path algorithms,a method for calculating traffic routes under specific route rules was developed.Finally,taking Chengdubei Station as a case study,the paper parsed specific route information from the National Railway Freight Traffic Routes document and calculated both the shortest and specific routes for all departure and arrival flows under the defined rules.The case study demonstrates the practicality and effectiveness of the proposed method,showing its potential to enrich the digital management of traffic routes and provide robust support for field-level traffic organization.关键词
