Abstract
State data of vehicles in a control area is collected, then time of starting control and selection of controlled vehicles are decided according to a position of a ramp merging vehicle, information is transmitted into a traffic control module by means of a data transmission module, and an artificial intelligence based ramp merging multi-objective control model ensures efficient, safe, and energy-saving operation of overall traffic of a road while completing ramp merging by means of a vehicle traveling track in the cooperative ramp control area. Compared with a traditional method, the present invention greatly promotes merging of the ramp vehicles, and different from other methods having the defect of transforming the problem of ramp merging into the problem of vehicle sequencing, the present invention greatly improves efficiency of ramp merging.
