The invention discloses a traffic guidance strategy realization method. Aiming at the problem that the phenomenon of 'congestion drift' exists in the existing traffic guidance strategy, the invention provides an AR* route guidance strategy of the same type by introducing a route counter impedance function defined according to guided vehicles and road characteristics into a shortest route cost function based on travel time. According to the improved guidance strategy, congested road section detection, guided vehicle selection and vehicle guidance grading are carried out first, and then, vehicles are guided to an optimal route enabling minimum travel time and route counter total cost function. Simulation results show that the two improved guidance strategy can reduce the occurrence of 'congestion drift' of a road network and the average travel time.
