The Research And Design Of Dynamic Traffic Information Guidance System Based On Data Fusion And GIS

Intelligent Transportation Systems have been widely recognized as the solution to many problems in the field of transportation. For many traffic management or application systems, traffic information, especially the dynamic traffic information is the core content, which is centric to various features of systems. As the focused research issue in the field of intelligent transportation system, Dynamic Traffic Information System is based on the processing and application of dynamic traffic information. The system can provide real-time, accurate and comprehensive traffic information and the best travel route guidance. Thanks to this system, the dynamic traffic information collected by the traffic management department can serve the public. On the other hand, some references about decision-making could also be provided for the traffic management department. Dynamic Traffic Information System Research and Development The main technologies involved in the research and development of Dynamic Traffic Information System include collection technologies of dynamic traffic information, data preprocessing, data fusion technology, shortest route guidance algorithm and GIS.This paper seeks to do some research and development of the Dynamic Traffic Information Guidance Systems. Some research in data fusion of dynamic traffic information and dynamic traffic route guidance technology has been done. Some related algorithms are improved to enhance their efficiency. And then, a Dynamic Traffic Information Guidance System has been developed based on GIS techniques.The main contents of this paper are as follows.To begin with, a brief introduction about Intelligent Transportation Systems and interrelated technologies including data collection methods and data preprocessing, data fusion technology is made. Then the paper puts the emphasis on the research of some common data fusion technology. After that, this paper develops the comprehensive statistical analysis algorithm to do data fusion for the dynamic traffic information.Secondly, after introducing some commonly used shortest path algorithms in the Dynamic Traffic Route Guidance system, a detailed analysis the classical Dijkstra algorithm is made. Then the paper improved the network storage model and search method of Dijkstra algorithm. And then, simulation is completed and the results demonstrate that the improved algorithm is highly effective compared with the classical one.And then, the paper designs the overall framework and data flow for the Dynamic Traffic Information Guidance System from the perspective of system development and design. After that, the data fusion module and shortest route guidance module are integrated with the GIS-platform. As a result, a Dynamic Traffic Information Guidance System has been designed and implemented to serve the general traveler and improve the efficiency of urban transport system.Finally, the research and development, as well as the following improvement of this paper is summarized.
