Reviewing Traffic Reliability Research

Multi-dimension, stochastic, and dynamic are essential nature of urban traffic operation. Traffic reliability introduces the idea of reliability into traffic research and is an important field of cause analysis of traffic problems. Considerable researches have been conducted on traffic reliability, covering from theory to practice, and from model to algorithm. There already exists a framework for reliability analysis. However, few comprehensive review literatures can be obtained. The goal of this paper is to fill this blank from describing of development of traffic reliability research. Basic definitions, theory, and methods are depicted accompanied with the application to traffic optimization. In the last section, the future development of traffic reliability research is concerned.

摘要多维、随机、动态是城市交通系统运行的本质特征，交通可靠性将可靠性思想引入交通研究中，形成了分析复杂交通问题的一个重要方面。针对交通可靠性，学术界展开了大量的研究，从理论到实践，从模型到算法，交通可靠性研究目前已经形成了初步的分析框架，但是目前尚缺乏这一领域的综述性文献。本文从可靠性研究历程出发，综述了交通可靠性的概念定义、基本理论和方法以及其在交通优化中的应用，最后对交通可靠性的研究进行了展望。
