The problem of road traffic efficiency is becoming increasingly serious,especially the rescue efficiency of e-mergency rescue vehicles with the increasing number of vehicles.when the rear emergency rescue vehicles follow at low speed due to the inability to judge whether they can safely overtake the slow moving vehicles in front,a safety prediction method was proposed to predict the safety of overtaking in curve sections based on vehicle road communication.The spe-cific research contents included:First,the vehicle road interconnection technology was used to obtain accurate road condi-tion information;Then a four degree of freedom vehicle dynamics model was established to calculate the safe speed;Fi-nally,the safety collision prediction algorithm for vehicles overtaking in curves was designed,and simulation verification was conducted through typical curve road conditions.The simulation results show that the method can provide accurate prediction information for drivers,effectively enhance the safety(no collision with opposite and same direction vehicles)and stability(no side slip and rollover of the vehicle)of overtaking,and improve the road traffic efficiency.
