Problems solved by technology

Since the right-of-way assignment problem at an intersection is a non-deterministic polynomial (NP)-hard problem, the methods provided by related technologies can only deal with scenes with fewer vehicles (less than 15 vehicles), and for more general scenarios with more vehicles scenarios (more than 20 vehicles), it is impossible to provide a real-time and efficient decision-making scheme for road right allocation; in addition, most of the methods of related technologies rely on the topological structure of the intersection. It cannot be deployed efficiently and quickly to the urban road network traffic system with various intersections
