Conceptual Design and Feasibility Exploration of Matrix-Type Rail Network (MRN)

摘要: 针对当前轨道交通系统中所存在的资源利用率低、运力配置不灵活等痛点问题，本文提出了矩阵式轨道网络(MRN)的概念模式，并且建立了一套弹性网格的轨道框架结构、单向循环的运行规则以及分级停靠岛的客货混运核心机制，把系统运作形式化解为“带时空网络约束的动态车辆路径”优化问题。本文创新性在于提出了柔性网格、分层分布式调度等解决方案，同时在工程施工、模型算法、经济效能及运营安全的四大维度上宏观剖析了MRN落地的核心难点，旨在为下一代轨道交通的范式革新提供理论层面的创新思路。

Abstract: Aiming at the pain points of low resource utilization and inflexible transport capacity allocation in current rail transit systems, this paper proposes the conceptual model of the Matrix Rail Network (MRN). It further establishes a core mechanism for integrated passenger and freight transport, which comprises an elastic grid-based rail frame structure, one-way circular operation rules and graded stop islands, and thereby transforms the system operational mode into an optimization problem of dynamic vehicle routing with spatiotemporal network constraints. The innovative contributions of this paper lie in the proposal of solutions including a flexible grid and hierarchical distributed scheduling. In addition, it conducts a macroscopic analysis of the core challenges in the practical implementation of MRN from four dimensions: engineering construction, model algorithms, economic efficiency and operational safety, aiming to provide innovative theoretical insights for the paradigm innovation of next-generation rail transit systems.
