基于道路行程时间的城市交通诱导模型研究

行程时间是交通出行服务水平的重要衡量指标，也是交通出行者所能直接感知的重要出行指标。良好的行程时间计算应用是进行道路交通管理、交通信息服务和路径诱导的重要支撑，亦是进行城市交通规划的重要数据支撑。本文总结了道路行程时间的有关参数及指标、行程时间的计算和行程时间分布规律，预测出城区任意两点间的近似行程时间，为城市交通诱导模型提供理论基础。

Travel time is an important measurement of traffic travel service level, and is also a key travel index which can be directly perceived by the travelers. Favorable calculation application of travel time is a vital support for road traffic management, traffic information service and route guidance, as well as a significant data support for urban traffic planning. This paper summarizes the related parameters and indicators of road travel time, the calculation and distribution principle of the travel time to predict the approximate travel time between any two points of the city, providing a theoretical basis for urban traffic guidance model.
