Research on Vehicle Conflict at Entrance of Expressway Based on Zero and Grey Game Model

Based on grey idea and game theory,this paper analyzes uncertain factors on conflicted vehicles at the entrances of expressways,presents that the conflicted vehicles when choosing strategies are restrained by interval grey numbers,and establishes zero and grey game model for conflicted vehicles.The calculations of algorithmic examples show the zero and grey game model reflecting the conflict of vehicles at the entrances of expressways objectively can perfectly conform to the realities.
