Although the technology of Internet of Vehicles (IoV) is developing rapidly, it will still take a long time to realize its overall popularization. Aimed at this transition phase, this paper proposes to set up an IoV lane on the urban road, which is specially designed for the connected vehicles, to provide a better driving environment for the connected vehicles. Considering the operation characteristics of traffic flow under traditional and IoV environment, this paper establishes a three-lane cellular automata model for urban road traffic flow considering IoV lane, modified on the basis of the Modified Comfortable Driving (MCD) model and symmetric two-lane cellular automata (STCA) model, and then takes simulation by MATLAB and makes analysis. The result shows that the setting of IoV lane can improve the velocity of networked vehicles to a great extent with no or just a bit decline in the ordinary vehicles’ speed, and it has a great effect on the mixture traffic flow, including the increase in both traffic volume and the average speed. What’s more, when the networking proportion is between 0.2 and 0.76, and the space occupation ranges from 0.18 to 0.56, the traffic benefit of IoV special lane can reach the best.

考虑车联网车道的三车道城市道路元胞自动机模型

车联网（IoV）技术虽然发展迅速，但要实现全面普及还需要很长时间。针对这一过渡阶段，本文提出在城市道路上设置专为网联汽车设计的车联网车道，为网联汽车提供更好的驾驶环境。考虑传统和车联网环境下交通流的运行特点，在改进舒适驾驶（MCD）模型和对称双车道的基础上，建立考虑车联网车道的城市道路交通流三车道元胞自动机模型。元胞自动机（STCA）模型，然后用MATLAB进行仿真分析。结果表明，车联网车道的设置可以在很大程度上提高联网车辆的速度，而普通车辆的速度没有或只是略有下降，对混合交通流有很大的影响，包括增加交通量和平均速度。更重要的是，当组网比例在0.2~0.76之间，空间占用范围在0.18~0.56之间时，车联网专线的通行效益可以达到最佳。
