Intelligent vehicle afflux method and device and intelligent road information physical system

The invention provides an intelligent vehicle afflux method, an intelligent vehicle afflux device and an intelligent road information physical system. The method comprises the following steps: acquiring an afflux interval, and calculating a minimum gap value of each gap based on communication time delay; determining a first convertible gap and a corresponding convertible parameter in combination with a preset collision avoidance condition; analyzing whether the to-be-converged vehicle meets the convergence requirement of the first convergence gap based on the vehicle performance, and determining a second convergence gap and a convergence strategy; and determining the second convertible gap at the foremost end as a target convertible gap, and sending the corresponding convertible strategy to the to-be-convertible vehicle, so that the to-be-convertible vehicle converges to the target convertible gap according to the convertible strategy. In the confluence mode, the limitation of a fixed confluence point is brok
