The Study And Development Of The Web-Based Management Information System Of Traffic Illegality

The Management Information System of Traffic Illegality (TIMIS) is an important part of the intelligence transportation management system. By the management and the whole distance supervisions to traffic illegality, the ability of transportation management can be improved greatly. At moment, the TIMIS has already got the extensive application in domestic and international transportation. But in all, the systems presented are developed mostly according to the distribute database system with C/S structure. Its high price, low efficiency and difficulty of maintenance are the main shortcoming. Moreover, the share of information is limited and it is hard to carry out the data integral processing. There is not an interactive interface with the driver. Because the development is large-scale, difficult, and complicate, and it is under network environment, so it is hard to find a successful case that the information system can combine with other part of the intelligent traffic management system effectively.Based on the development of Hunan Transportation Information Management System, this paper has presented how to develop a TIMIS based on a mixed structure of B/S and C/S. The system is developed with Oracle database and has reserved enough resources and interface for the upgrade and extension. The main work includes:1. Having presented a reasonable software development method, object-orientated design based on UML, by the comparation of instance and the analysis of theory and combined with the research background. So it can guarantee the software model and the reasonable structure of the system.2. Having studied the application for database modeling and having resolved the problem of the represent and realization of complex connection in database and the problem on data integral processing. Having implementing the open interface between many standard data formats for exchanging;3. After having studied the Web technology and middle-ware technology, we implement the system with 3-tiers structures. Aimed at the applied environment of the system, we resolve the safe problem of Web with the mature project of EASI.This paper is valuable for the domestic study in realization of TIMIS. And it has important and actual meaning for the study of the 3-tiers structures optimizing and the application of Web, middle-ware, data security technology to the development.
