Description

technical field

[0001] The invention relates to the field of route optimization of vehicle navigation systems. Based on the analysis of unimpeded reliability, a design and implementation of a delay risk avoidance standard with the dual objectives of minimum blocking possibility and shortest transit time in the absence of real-time information or limited real-time information An Efficient Algorithm for Dynamic Route Optimization. Background technique

[0002] Vehicle navigation system (VIS), as one of the applications of intelligent transportation system ITS, not only provides users with better route information services, but also helps reduce traffic jams, shorten travel time and save energy, so it has been widely used in recent years. Optimal route optimization is an important key technology in vehicle automatic navigation system. Our research in this area is still in its infancy. According to the source of information based on route optimization, vehicle automatic naviga...
