A STUDY ON METHODOLOGY FOR EVALUATION AND MANAGEMENT OF VARIATION IN LEVEL OF SERVICE OF ROAD TRANSPORTATION BASED ON TRAVEL TIME RELIABILITY

本文提出了一套在丰富的动态交通数据可用性下，道路交通系统服务水平（LoS）及其变化的分析和评价方法。此外，本文还提出了提高道路运输系统LoS的交通管理对策。本研究的主要成果如下：1)基于路网旅行时间可靠性的概念，提出了道路运输系统LoS的评价方法。2)提供出行时间分布信息有助于提高交通管理水平。

This study proposes a set of methodologies to analyze and evaluate the Level of Service(LoS) provided by road transportation system and its variation under the availability of rich dynamic traffic data. In addition, this study proposes countermeasures for traffic management to enhance the LoS of road transportation system. Major outcomes of this study are as follows. 1) We develop the methodology to evaluate the LoS of road transportation system based on the concept of travel time reliability of network. 2) This study suggests that provision of distribution information on travel time might helpful for enhancement in traffic management.
