Based on the two-lane, symmetric traffic model (STCA), a modified traffic model, including Vehicle-to-Infrastructure (V2I) communication (STCA V2I model, for short), is presented. The combined full-autonomous and semi-autonomous vehicles are able to exchange information as well as the intentions of the driver with the surrounding vehicles through V2I communication. In the analyzed case, the communication between vehicles includes the sending of information to vehicles to the rear about the traffic situation ahead. Numerical simulations present a greater dispersion of vehicles with the same traffic density and fewer lane changes, while maintaining the same average vehicle speed as in the STCA model. Spatial–temporal profiles of traffic flow indicate that vehicles moving in accordance with the STCA V2I model are not subject to unnecessary concentration. Numerical studies have shown the positive and negative effects of transmitting traffic congestion messages.

考虑车路通信技术的元胞自动机交通模型计算机仿真

基于双车道对称交通模型（STCA），提出了一种改进的交通模型，包括车辆到基础设施（V2I）通信（简称STCA V2I模型）。组合的全自动和半自动车辆能够通过V2I通信与周围车辆交换信息以及驾驶员的意图。在分析的案例中，车辆之间的通信包括向后方车辆发送有关前方交通状况的信息。数值模拟显示，在保持与 STCA 模型相同的平均车速的同时，具有相同交通密度和更少车道变换的车辆分布更大。交通流的时空分布表明按照 STCA V2I 模型行驶的车辆不会受到不必要的集中。数值研究表明传输交通拥堵信息的积极和消极影响。
