Design Of Expressway Ambiguous Path Identification System Based On 5.8G DSRC Technology

With the continuous development of the highway network,the road network is more and more complex;the highway multipath problem appears to be particularly prominent.Currently,toll expressways in Tianjin use the shortest path toll and the shortest path splitting method,which causes the collection and splitting of toll fees unfair and unreasonable.It is easy to cause controversy among the owners of expressways.Therefore,in order to solve the unreasonable and unfair toll collection and split toll,it is very necessary to speed up the application of accurate path identification technology to achieve accurate path identification.First,the thesis describes the path and system of path identification system with the gradual complexity of the national highway network and the emergence of ambiguous path.Combined with the status quo of the development of path identification system both at home and abroad.Secondly,it analyzes the various existing ambiguous path identification techniques.Path recognition includes two major categories: probability identification and accurate identification.By analyzing various technology implementations and comparing the advantages and disadvantages of various technologies,it is found that the 5.8GHz technology can simultaneously solve the path identification of MTC and ETC vehicles with obvious Therefore,it is determined that 5.8GHz dedicated short-range communication technology will be used in the design of highway ambiguous path identification system.Thirdly,the principle of 5.8GHz dedicated short-range communication technology path identification is analyzed,and the key technologies of 5.8GHz path identification technology are analyzed and researched.From the system architecture,system functions,system workflow and equipment requirements form the ambiguous path identification based on 5.8G technology overall design.Finally,according to the background of the whole road network in Tianjin,the status quo of network charging and the problems faced by the network charging,this paper puts forward the design scheme suitable for the polytope path identification of expressway in Tianjin.Through researching on the technology of ambiguous path identification,the ambiguous path identification technology based on 5.8GHz can realize the accurate identification of path information,and solve the problem of unreasonable toll collection and unfair splitting,which has practical significance and promote the value.
