Abstract

The invention discloses a generalized vehicle-road cooperation system and method. The method comprises the following steps of collecting traffic related data and vehicle characteristic data through a traffic information collection module, matching collected information with a data collection position and a map data position in a spatial dimension, forming an information time sequence relation in a time dimension, using the map data as a basis, fusing traffic structure characteristic points, using roadside intelligent facilities as relative positions, and fusing related information according to a facility coverage range, and forming traffic information based on the position, respectively processing different traffic information with spatial attributes to form traffic control and service information based on vehicle positions, classifying various types of information according to emergency degrees, and performing information release and control according to different types of vehicles and different release means. Traffic safety management and control and precise service can be realized, traffic safety is ensured, and travel efficiency is improved.

Description

technical field [0001] The invention belongs to the field of intelligent transportation, and specifically relates to a generalized vehicle-road coordination system and method for safety control and precise service. Background technique [0002] Safety and efficiency are the goal and development theme of expressway operation. Expressway operation management ensures the safe driving of people, vehicles and roads from two aspects of emergency monitoring, and effective and efficient service, management and decision-making. Wisdom Expressway conducts demand analysis from two aspects: safety management and control and precise service. By comprehensively deepening data development and sharing, improving the monitoring system, and ensuring communication, real-time knowable, measurable, controllable, and serviceable will be realized. The development direction of smart transportation must be a comprehensive transportation system integrating people, vehicles and roads. Vehicle-road c...
