| The rapid development of Internet technology has greatly enriched the mode of data transmission, the ability to dig out available information from huge data is limited. Using computer graphics, and image processing technology, we can optimize data visualization method. With the help of the maps, by fusing WebGIS with visualization technology, it will be beneficial to mine data information at depth. ETC has been promoted by networking in the whole country, which has great research significance and development prospects. Based on the advantages of the above, this thesis describes a visualization experimental system for ETC traffic based on WebGIS.The system takes Lanzhou as the research area, to select some representative sites as ETC toll site monitoring terminal experimental sample point, we can use GPRS to transfer the ETC traffic data to the server, and the sever will deal with a variety of data and based on the open source GIS platform. The visualization experimental system of ETC traffic was establish based on WebGIS for expressway toll station and parking lot.Firstly, we use the ETC-II as platform which was produced by Beijing BoChuang company to provide hardware foundation for the vehicle information real-time collection, so that we can simulate charge the cars ETC traffic fees by FRID technology and Zigbee technology, then we also can use SIM 900 A GPRS module to transfer the ETC vehicle data.Secondly, the monitoring center received the vehicle data and visualized, combined with GaoDe map’s JavaScript API, we can get the ETC traffic map visualization system which based on B/S architecture. This system can provide ETC parking information for the ordinary users and provide the ETC traffic vehicle specific information for the advanced users.Finally, we test the whole system in laboratory and verify the feasibility of the system to accumulate experience for the late promotion.ETC system has been rapidly developed across the country and completed the work of the national network in 2015, but the function is still stuck in the application of collect fees. The innovative point of this thesis is rationally to combine with ETC traffic and WebGIS technology, it will expand the function of the ETC system, and it will have a good prospect in the field of intelligent transportation. |
