摘要

摘要: 为解决综合交通体系中不同交通方式各自为政、条块分割的问题，研究了综合交通体系融合发展中缺乏一体化交通分析技术的瓶颈，提出了以交通枢纽为关键，覆盖铁路、公路、水运、航空、管道以及城市道路的“多网合一”的物理网络与虚拟网络拓扑结构模型; 构建了服务各交通运输方式、结果量化可比的交通阻抗函数模型与优势运输距离模型; 研发了异质交通网络环境下的一体化交通分配模型与算法，提出了综合交通系统客运组合出行与货运多式联运的交通量分析方法，形成了服务于综合交通系统一体化融合发展的交通分析模型与技术体系; 通过完全自主的“交运之星——TranStar”综合交通版交通仿真分析软件，搭建了综合交通系统虚拟仿真平台，实现了对大规模综合交通网络规划建设与运行管理的快速响应，并验证了分析模型与算法的可行性。研究结果表明：相比传统分析方法，提出的交通分析模型与算法可满足“多网合一”条件下综合交通系统的各类分析需求; 利用提出的交通分析模型与算法对综合交通网络的交通流量进行分析，相对误差不超过3%，平均误差不超过2%，分析结果精度高，满足工程实践要求。

Abstract: To solve the problem of fragmentation in comprehensive transportation system, the technical bottlenecks in the integration of comprehensive transportation system were addressed. The topological models of multi-network integration consisting of the physical and virtual networks with comprehensive transportation hubs at their core, and considering railways, highways, waterways, airlines, pipelines, and urban roads, were proposed. Traffic impedance function model and advantage transport distance model serving each traffic mode and quantifying the results were constructed. Integrated traffic assignment model and algorithm under the condition of heterogeneous network traffic distribution were developed, and a analysis method of traffic volume for passenger combined travel and freight multimodal transport in integrated transport system was proposed. The traffic analysis model and technical system to serve the integrated development of comprehensive transportation system were built. TranStar (Comprehensive Transportation Version), an independently developed software, was implemented to build a virtual simulation platform for the comprehensive transportation system, enabling the rapid responses of large-scale comprehensive transport network's planning, construction, operation, and management to be realized. The feasibility of the models and algorithms were also verified. Research result shows that compared with the traditional analysis methods, the proposed traffic analysis model and algorithm satisfy the diverse analytical demands of a comprehensive transportation system under the condition of multi-network integration. The traffic flow of a comprehensive transportation network is verified by the proposed traffic analysis model and algorithm. The relative error is less than 3%, and the average error is less than 2%. The analysis result is of high precision and meets the requirements of engineering practice. 5 tabs, 10 figs, 31 refs.
