In order to solve the problems of disorderly traffic,low traffic efficiency and frequent accidents at intersections without traffic signals,this paper proposes to apply a vehicle-road coordination system,fully consider the difference between networked vehicles and traditional vehicles,establish a coordination model of non-signal intersections,and coordinate the traffic of vehicles at intersections without traffic signals.The coordination system calculates and coordinates the mixed traffic vehicle information at the intersection without traffic signals,and calculates the priority according to the principle of"first come,first served",which is conducive to improving the traffic efficiency of the intersection.Vehicles in the same phase with no risk of cross-collision in the driving path are allowed to pass through the intersection together with vehicles driving in the same lane and following the vehicle at a small distance from the front and back.According to the time it takes for the vehicle to reach the stop line,T1 size can be divided into a number of different levels,and the highest priority vehicle or vehicle community obtains the right of way,which can drive normally through the intersection,and other priority vehicles have no road right.When the road right needs to be transferred,the road right is transferred to the next phase vehicle 2S in advance,so that the driver has enough reaction time and reduces the idle time at the intersection.
