The Design And Implementation Of The Highway Geographic Information System Based On ArcGIS

With the development of city modernization and information construction, the popularity of vehicles in the life will be improved.Traffic situation is becoming more and more serious problem.In view of the difference of highway construction in Guizhou province and other provinces.Guizhou Province, the main trend of the investment of the highway will be different, more bridges and tunnels. The other provinces’ s investment type tend to be single.With the increase of highway construction, the road of the "two meaning" road also increases,the vehicle from the starting point to the end of the road can be a variety of travel, similar to the "closed loop" road.But the road on the “closed loop” was built by the different investment business owners.So the Department of highway vehicles management and vehicle cost split is also facing a huge challenge,So it is very urgent and important to construct the highway vehicles. the highway geographic information system has received extensive attention in this background.This paper introduces the research background, domestic and foreign research status and future development trend of the highway geographic information system.Taking the expressway in Guizhou Province as an example, the research design scheme and implementation of the highway geographic information system are put forward.The key technologies of asynchronous communication, Ajax,Server ArcGis architecture, development mode, Engine ArcGis components, such as the characteristics of a detailed exposition and research.Focus on solving the "two means" path of network toll road network costs split standards.On the established map model.Quick get the shortest path and the minimum amount of query results, to provide the corresponding data for each owner, etc..The system through the development of Microsoft Corp studio visual platform.Under the System development, using C# development language to call the COM protocol components provided by Engine ArcGis.System has mainly realized the control and display of the map layer、path and expense to proofread and query、playback of travel History road、Spatial data query、display the shortest path and the minimum charge and other key functions.To optimize the road,increase the rate of road traffic,reduce the human intervention and labor cost,the system provides some important methods. In the application background of guizhou highway shows the function of the whole system.It has played a good role in the development of the highway geographic information system in the future.
