摘要： 经过长期的交通基础设施建设和机动化发展，北京市道路网络已经形成并且道路网络系统的供给能力和服务需求日渐趋近，路网供需之间的平衡变得脆弱，路网的交通拥堵更加容易发生，偶然事件对整体网络的破坏性影响越来越大。路网可靠性评相对传统评价指标，它能够另一个侧面反映路网运行的波动性，评估路网承受扰动的能力。出租车是北京道路交通系统的重要组成部分，其运行状态对北京市道路网络整体的状态具有较好的代表性。本文以出租车车载智能卡采集的载客行程时间数据为基础，研究提出新的单位距离行程时间可靠性评价指标和方法，并使用该指标和方法对北京市路网的可靠性水平进行实例评价。

Abstract: With the booming of urbanization and motorization, the transportation system is becoming more and more unreliable due to the weak balance between supply and demand. Transportation network reliability study is developing very fast around the world which is a new technology to evaluate the stability of the transportation network, especially when disturbance or incident occurring. Thus, it is necessary and important to study the road network reliability to support planning and operation in Beijing. Taxi is one main component of traffic flow. The smart card, IC card which is installed in taxi can record the travel time and distance per trip. Using the smart card recorded data, the travel rate time per trip can be calculated, and the regulation of travel rate time by taxi can be fond from the cumulative taxi datum. In this paper, three new reliability indices and methodologies about travel rate time are developed, and Beijing transportation network reliability is analyzed by using these indices and the taxi trip datum.

Key words: Road Network Reliability, Travel Rate Time Reliability, Evaluation Index
