1. The application subsystem includes traffic information collection system, signal light control system, traffic guidance system and parking guidance system. Make full use of the collected information, timely release the corresponding traffic congestion situation, guide the best route information, and provide reference for travelers. For the traffic flow information of each traffic trunk line, reasonably control the length of traffic lights to reduce traffic congestion; For vehicle failures, timely release road information and notify the accident handling agency.
Traffic guidance information includes information from automatic acquisition systems such as microwave acquisition and video acquisition, as well as information about traffic incidents, traffic accidents, traffic control, traffic alarms and so on. All data are fused by the data computing center system and released on the traffic guidance screen in real time, which provides convenience for travelers.
By collecting the information of passing vehicles and queue length collected by electronic police, smart card port and traffic detection system, combined with the historical traffic time of the road network, the traffic situation of the road network can be detected in real time, and at the same time, the traffic guidance system will release traffic information on the outdoor traffic guidance screen to provide convenient and fast traffic data for travelers.
2. The traffic information service center includes six parts: remote service module, remote monitoring module, pre-test module, online operation and maintenance module, data exchange module and consulting management module.
3. Command and control center includes traffic facilities data platform, traffic information data platform, GIS platform, application management module, data management module, operation and maintenance module and information release module. With the support of GIS platform, the command and control center establishes the component and event platform. Components mainly refer to transportation facilities. Through the management of each application subsystem, aiming at centralized management, it has the functions of data analysis, data mining, report generation, information release and centralized management.
Intelligent transportation system mainly solves the application requirements.
1, real-time traffic monitoring. Know where the traffic accident happened, where the traffic is crowded and which road is the most smooth, and provide it to drivers and traffic managers as quickly as possible.
2. Public * * * vehicle management. Realize the two-way communication between the driver and the dispatching management center, and improve the operating efficiency of commercial vehicles, buses and taxis.
3. Tourism information service. Provide all kinds of comprehensive traffic information to outbound passengers in time through multimedia and multi-terminals.
4. Vehicle auxiliary control. Use real-time data to help drivers drive cars, or to drive cars automatically instead of drivers.
