The Research on the Ambiguous Path Identification Technology of Expressway Based on GIS

Abstract

With the expressway forming the network, different construction costs of expressway sections cause the ambiguous path problems of the expressway network. The identification of the expressway ambiguous path is the key technology that relates to the expressway's interconnection toll fair, accurate and efficient. This paper discusses the expressway bottleneck problem of ambiguous path in the interconnection tolls and its causes. Analysis of the status of the studies of the ambiguous path identification technology. The paper discusses and points out the principles and methods of the ambiguous path identification based on GIS / GPS technology. Through the author's experiments, proves to have advantages of with less investment, interconnection tolls accurate, and convenient. It will be the main direction of the ambiguous path identification and interconnection tolls.
