摘　　要：讨论了高速公路联网收费与拆分系统中亟需解决的瓶颈问题——多义性路径及其产生的原因,分析了目前国内多义性路径识别的主要技术,重点研究和探讨了运用GIS进行多义性路径识别的原理和方法.经过作者在郑少高速公路等路段的试验,证实了交通网络分配模型和GPS/GIS技术识别多义性路径,具有快速、准确、误差相对较少的优点,将是今后高速公路多义性路径识别与联网收费及拆分系统的主要方向.This paper discusses the expressway bottleneck problem of ambiguous path in the interconnection tolls and its causes, the status of the ambiguous path identification technology was analysed. The paper also discusses and points out the principles and methods of the ambiguous path identification based on GIS technology, which include the methods of the shortest path, traffic probability allocation model and GPS/GIS. The experiments proves to have advantages of with less investment, intereonnection tolls accurate, and convenient about the principles and methods of the ambiguous path identification based on GIS technology including the methods of the shortest path, traffic probability allocation model and GPS/GIS. It will be the main direction of the ambiguous path identification and interconnection tolls.
