The Study And Simulation Of Expressway Electronic Toll Collection System

Intelligent transportation system(abbreviated to its) is a comprehensive transportation administration system, which feayures availability,accuracy and high effciency.By adopting the modern high-tech upon comprehensive transportation administration system of the whole ground,it indicates the future development of transportation and imporves the whole ground transportation system for its flexibility,safety,efficiency and resource utilization. Electronic Toll Collection (abbreviated to ETC),a special function of ITS,is a unique example applied to road transportation system.By adopting the modern high-tech,it is an administration system widely used in the toll station of road,bridge and so on in the world.Its main feature is that the computerized facilities could complete the charges for the vehicles automatically when they pass through the toll station with a high speed without stop.This paper gives a introduction on the current situation of the Electronic Toll Collection,and gives a concrete instruction on the double-chip Electronic Toll Collection.The technology has carried out description summarizing on whose key.The Electronic Toll Collection consists of the AutomaticVehicle Identification,the Automatic Vehicle Classification and the Vehicle Enforcement System. The On Board Unit of the double-chip Electronic Toll Collection is composed of the tag and the double-interface CPU card.It has two working mode that one is non-parking with tag and card the other is parking with card only.The paper has put up the entire ETC toll systematic frame with a view of the Shaanxi Province reality , brought forward every part hardware , software design and request. The software has carried out detailed description on charge for lane,it designs entrance and exit handle technological processres pectively on corrding to the ETC and MTC.In the end realized charge for lane software simulation emulation with VC.
