Based on the previous research results, this paper applies cellular automata to the research of two lane traffic flow, and introduces the vehicle-to-vehicle communication mechanism under the environment of the Internet of vehicles. In the lane changing rules, it focuses on the consideration of the relative speed of vehicles in front of and behind the adjacent lane and the vehicle in front of the lane, so as to increase the chance of lane changing as much as possible. After analyzing the traffic characteristics under the environment of the Internet of vehicles, the MATLAB software is used to simulate the traffic flow, and the traffic flow parameters are obtained under different initial density and different penetration rate of Internet of vehicles. The simulation results show that: the vehicles in the Internet of vehicles environment have a better running state, specifically, it can increase the chance of vehicle lane change, alleviate the traffic congestion to a certain extent, improve the driving speed, and make the vehicle operation more orderly. But at the same time, it can also be found that the Internet of vehicles only optimizes the traffic flow, and does not increase the capacity of the road.
