Abstract: For the ambiguous paths of highway network, a highway pass card design based on BeiDou positioning technology is proposed. The highway pass card, which can record the precise position information of vehicles' movements, is realized through integrating BeiDou chip and Electronic Toll Collection (ETC) pass card. By matching the position record to map data, the actual vehicles' traveling tracks can be obtained, and then the highway tolls will be collected according to the traveling tracks. This design solves the ambiguous paths problem effectively, and can contribute to realize highway wide range network toll collection. Compared with the RFID technology and license plate recognition method, this solution has some advantages such as its precise recognition result, less modification to existing system and external influence etc, having the comprehensive value of application.
