摘要: 针对CACC车辆与普通车辆混合行驶的道路环境,综合考虑交通流、信息流与病毒传播之间的相互关联,计算CACC车辆病毒感染概率,构建出车联网环境下的CACC车辆病毒信息传播动力学模型。之后分析了不同环境下CACC车辆病毒感染概率,并对病毒信息传播过程进行仿真。仿真结果表明:无论是在不同的通信范围限制条件下,还是在不同的交通流密度环境中,都可以通过降低CACC车辆病毒感染概率来有效控制病毒信息传播范围,提升CACC车辆信息传播安全性。

Abstract: To analyze the virus propagation under the road environment mixed with CACC vehicles and common vehicles, considering the interaction among traffic flow, information flow and virus propagation, CACC vehicle virus infection probability is calculated and the dynamic model of virus propagation is built. Then, the probability of virus infection under different environments is analyzed and the process of virus propagation is simulated. The simulation results show that reducing the probability of virus infection can control the spread of virus effectively and improve the security of information propagation of CACC vehicles,both in different communication range limits and in different traffic density environments
