单向交通组织条件研究

Research on One-Way Traffic Organization Conditions

摘要: 交通拥堵已成为城市共同面对的难题，在解决交通拥堵问题上，单向交通是一种重要的交通组织方式，为了解决单向交通评价中主观性较强及网络效应考虑不足的问题，本文探究了考虑绕行效应的单向交通综合评价模型，并尝试建立从微观仿真数据向层次分析法(AHP)决策权重的客观映射机制，旨在为城市单向交通组织提供更具量化支撑的决策依据。本文在整理前人文献的基础上，总结了单向交通的基本概念及其优缺点，对单向交通路段交通特性以及单向交通网络模式特性进行分析。介绍了层次分析法的基本原理，并运用层次分析法构建了综合评价模型，将单向交通这一问题分解为多个组合因素影响的层次结构。本文通过交通仿真软件VISSIM构建仿真道路，运用软件输出项获取道路运行指标统计数据，将仿真结果用于层次分析法中各层的比较以对评价模型进行验证，最终得出在不同条件下应优选哪种方案。

Abstract: Traffic congestion has become a common problem faced by cities. One-way traffic is an important traffic organization method for solving this problem. To address the issues of strong subjectivity and insufficient consideration of network effects in one-way traffic evaluation, this paper explores a comprehensive evaluation model for one-way traffic that considers detour effects. It also attempts to establish an objective mapping mechanism from microscopic simulation data to the decision weights of the Analytic Hierarchy Process (AHP), aiming to provide a more quantitatively supported decision-making basis for urban one-way traffic organization. Based on a review of previous literature, this paper summarizes the basic concepts and advantages and disadvantages of one-way traffic, and analyzes the traffic characteristics of one-way traffic segments and the characteristics of one-way traffic network patterns. The basic principles of the AHP are introduced, and a comprehensive evaluation model is constructed using AHP, decomposing the one-way traffic problem into a hierarchical structure influenced by multiple combined factors. This paper constructs simulated roads using the traffic simulation software VISSIM, uses the software output to obtain statistical data on road operation indicators, and uses the simulation results to compare the various layers in the AHP to verify the evaluation model, ultimately determining which scheme should be preferred under different conditions.
