面向车联网的交通应急管理可视仿真方法

With the development of global urbanization, the number of cars in the city grows rapidly. All kinds of emergencies can easily cause traffic congestion, which brings great challenge for urban vehicle emergency management. Combining with the development of Internet of Vehicles (IoV) technology, the status of vehicle virtual simulation was systemically summarized. The key technology was comparatively analyzed, including traffic simulation, crowd mood models and virtual reality simulation. Vehicle emergency management and virtual reality technology were combined, visual simulation framework for traffic emergency management was proposed. Through IoV monitoring technology, vehicles and driver information were obtained, driver's emotions were perceived timely. The vehicle crowd behavior was observed by three-dimensional (3D) visualization. All the work provides a new way for carrying out intelligent traffic emergency management.
