基于浮动车技术的城市路网功能层次分析方法

A Method to Analyze the Functions of the Road Network Using Floating Car Data

摘要: 介绍了一种基于浮动车数据的城市路网功能评价的研究思路和研究方法,利用浮动车数据对事例城市现有路网功能层次进行了分析,发现存在高等级道路承担了过多的短途出行、出行非直线系数(行驶距离与直线距离之比)过高等问题。并针对上述问题提出了路网功能整合建议.

Abstract: The auther addressed a new method to analyze the functions of the road network using Floating Car Data(FCD).The tracking data of GPS equipped and saved on floating cars was collected and matched with GIS data for the city.It shows that many roads with high level functions carry lots of short trips and the detouring rate(actual travel distance v.s.direct distance)is very high due to the inadequate functional hierarchy of road network which inflecting the performance of the network.The author also gives some advices directed at the problems mentioned above.
