The colorful neon effect shows the direction of the expressway on the GIS map, and it is carried out in the form of animation extension Display, let people shine. Cooperating with the road animation effect style diagram at the bottom, it fits the whole project scene better.
Tupu Software applies its self-developed core product HT for Web GIS to realize an interactive Web smart expressway traffic visualization management operation and maintenance platform, and provides a rich visual display of its geographic information system (Geographic Information System, GIS) data. The expressway visualization large screen combines GIS maps, supplemented by left and right panels for display. It is integrated from several dimensions such as tunnel machine room, ETC gantry, service area, toll station, etc., to control the operation status of road traffic in an all-round way.
The integration scheme of HT and GIS can provide the actual needs of the project to build a roaming route, and roam around various areas of the city according to the designated route. When formulating the route, you can refer to key areas or areas with a high level of intelligence to formulate and present to users Highway key development areas and intelligent development results. On the basis of the expressway BIM model, GIS information is integrated, and the geological and geographical conditions under different planning schemes are comprehensively analyzed, so as to avoid geological disasters and environmentally sensitive areas in road planning. At the same time, an optimization algorithm is embedded in the CIM (City Information Model) platform to further correct the planned route of the expressway.
The HT for Web GIS product supports the loading of different GIS data such as map tile service data, 3DTiles format data of aerial oblique photography and urban buildings. The urban architectural scene in this system achieves a practical and realistic effect by simulating 3D modeling of the buildings provided by the map supplier.

system analysis
ETC visualization
ETC gantry system is a high-speed non-stop charging facility. Some equipment for identifying car information can be installed on the gantry. According to the short-range communication between the vehicle-mounted RFID tag assembled on the front windshield of the car and the microwave antenna on the gantry of the ETC lane of the toll station, use the software Connect network technology applications with financial institutions to carry out background management and clearing solutions.
Video Surveillance Intelligent Analysis
Video surveillance intelligent analysis system is an indispensable means of supervision of road traffic.
