With the development of new technologies such as computer network and communication system, the highway traffic net is to be more consummate, traditional charge cannot meet the demand that require quickly, accurately, and efficiently. According to the advanced technologies of highway traffic communication network and the data transmission requirement for toll management system, this paper put forward the project for toll management system of highway traffic based on computer network, used IC card management system as the passing medium, and gives a sufficient discussion on the goal and structure of toll management system． 1. Introduction

Intelligent toll management system of highway traffic is designed to resolve the problem of different charging unit on the road, and the charging unit set their own closed facilities for charging independently. Traditional toll management is lack of uniform technical criterion and supervisory mechanism [1-2]. This paper research toll management system of highway traffic is easy to upgrade to meet the centralized management. System and other related systems to achieve the sharing of resources, and it provide communications and information services to transport system and community.

As toll management system of highway traffic used advanced, reliable technology and mature equipment, therefore it can reduce the staff on duty in the toll of the control room, lower operating cost management. And the use of networking system for manage department is easy centralized supervision and management. This will change the traditional "one company for one way, construction integrating with manages” management structure and operation of the charges shortcomings. It will be an inevitable trend in the future development of a modern payment system.

2. System Analysis and Description

As the defect of traditional toll management system leads to every highway section carry out an independent of highway charge. And the adjacent sections are connected with the main line toll stations, which resulting in the main line of toll Station is intensive, so it restricted the road traffic capacity into full play. Facilities of charge

and technology are also incompatible with each other, which would give rise to an increase of building and operating costs. Toll systems can not effective interconnection will resulting in Lack of effective integration of resources and so on [3-5].

This system uses artificial judgment vehicle type in the entrance, release traffic-ticket of non-contact IC card, exit artificial recheck vehicle type, recovery of non-contact IC card and collect tolls. When the vehicle to pass the vehicle detector, it will check the number of vehicles. The computers is semi-automated statistical management charge standard. Traffic-ticket uses the repeated non-contact IC cards. Charge business is mainly to receive cash, but also have credit cards and others payment methods prepare for highway. Each section by section from the jurisdiction of the management system can be designed for two-level computer administration system, that is the computer system and toll charges center computer system, and set aside the interface with the parent body.

The entire highway system is consists of various management centers that owned the charges center computer system. And all sub-toll stations manage themselves computer systems, as well as sub toll stations of exit/ entrance lane toll system. Charging system has the following basic requirements: full closed the charge structure, traffic-ticket of non-contact IC card, toll stations and the sub center is two-level administration system, advanced communications equipment: Fast Ethernet LAN and WAN SDH fiber. 3. Architecture of Application Systems 3.1. Toll System

Intelligent toll management system of highway traffic has two-level administration system, their mutual relations: charges sub center is responsible for the supervision and management of toll stations, toll station manages each toll lane. Each one is a complete computer management system, sub-centers with toll stations through SDH synchronous digital network rapidly transfer data of charges, toll stations through LAN to implement monitoring and acquire related charges information. Toll station and sub center relations is shown in Figure 1.

Figure 1. Relationship diagram of toll station and sub center 3.1.1. The computer system of charges sub center. The computer system of charges sub center is set in the central control room used for the collection of the changes data that from each station's computer system so as to complete the combined audit. The computer system of charges sub center through communication systems

connected with all the toll station of the computer system. Charges sub center is constituted by a computer system that link several small computers LAN and the corresponding software components, and its main function is to provide statistics and road data of each jurisdiction charges collected by the station computer system, to manage the IC card, to scheduling and real-time enquiry, to establish the network model of demolition clearing accounts. And according to data of traffic charges established analysis and decision-making module, the computer system through the toll stations will transmitted charge standard and system parameters that from the Center to the lane controllers. The computer systems of charge sub center, computer of tall stations and the lane controller work independently. Toll station and the computer of lane controller can not be affected to operate independently when the computer system of charges sub center fault occurs. Figure 2 shows network structure relationship diagram of toll sub center.
