Based on the OV model, this study, by taking into account individual vehicles’ perception of the road ahead in the mixed traffic flow, established a car-following model of multiple distances and analyzed its linear stability theoretically. The platoon, mixed with the vehicles of multi-distance car -following characteristics, is more stable and the large acceleration in OV model can be improved. It applied the car-following model of mul- tiple distances into the modeling of driving behaviors and traffic flow in mixed traffic flow. The numerical simu- lation was demonstrated to study the mutual transformation between high -speed steady state and low -speed steady state in the mixed traffic flow with different cart proportions and traffic entropy. The research results show that the traffic wave in the mixed traffic flow spreads faster and the time of acceleration and deceleration is shortened, which, to a certain degree, can alleviate traffic congestion. It maintains that with the increase of traffic entropy, traffic congestion becomes less and less obvious.
