摘要/Abstract

摘要： 在城市群交通一体化迅速发展的大背景下，本文针对城际铁路的运输能力计算问题提出一种与之相适应的计算模型。首先，文章在分析城际铁路运营特点基础上，基于整数线性规划建立计算模型，该模型利用平均最小间隔时间法中将两列相邻的列车组合为运行列车组作为运行图结构单元的思想来计算列车占用运行图总时间，并以最大化运行列车组总数为目标函数，以规定列车占用运行图总时间的有效时间范围为约束条件。最后，文章通过京津城际实际数据算例，验证了文章所提计算模型相较于传统计算方法更切合城际铁路运营实际。该模型大幅简化了城际铁路线路运输能力的计算步骤，提高了计算效率，能够助力于改善城际铁路运输能力及其运营服务水平。

Abstract: In the context of rapid development of traffic integration among urban agglomeration, a calculation model is proposed to calculate transport capacity of intercity railway lines. Firstly, on the basis of analyzing the characteristics of intercity railway, an integer linear programming based calculation model is formulated. Similar to the average minimum headway method, the proposed model calculates the total occupied time in train timetable by combining two adjacent trains into an operation train group. The objective of the model is to maximize the total number of operation train groups, where the total occupied time of train in train timetable is constrained to a certain range. Second, based on the real data of the Beijing-Tianjin intercity railway, numerical examples are presented to illustrate the effectiveness of the proposed calculation model, and verify the superiority over the traditional calculation method. The model greatly simplifies the calculation steps of transport capacity of the intercity railway, which makes the calculation more efficient. Moreover, it can contribute to improve the transport capacity of intercity railway and its operation services.

Key words: operation train group; intercity railway; transport capacity; integer linearprogramming
