Regional road network collaborative management method and system based on cross-operation subject data interaction

Abstract

This invention relates to the field of traffic control technology, specifically to a regional road network collaborative control method and system based on cross-operating entity data interaction. The method determines the dominant impact mode of an event as either propagation-type or regional-type. In the propagation-type mode, a congestion diffusion trend index is determined based on real-time traffic flow information and impact intensity indicators of the upstream and downstream locations. In the regional-type mode, an environmental gradient index is determined based on environmental monitoring values ​​and environmental values ​​from nearby monitoring points, and a safety warning radius is determined based on real-time traffic flow information and standard reaction time. A spatiotemporal window is determined according to the mode, including an interaction space range and an interaction time window: in the propagation-type mode, the interaction space range is defined based on vehicle congestion, and the interaction time window is determined in conjunction with the congestion diffusion trend index; in the regional-type mode, the interaction space range is defined based on the safety warning radius, and the interaction time window is determined in conjunction with the environmental gradient index, thereby improving the effectiveness of collaborative control.
