采用时域有限差分法分析了交叉口V2V通信中周围建筑物对大型车辆遮挡的影响。在传播损耗方面，将时域有限差分分析结果与射线追踪分析结果进行了比较。虽然大型车辆的阴影会产生很大的衰减，但来自建筑物的反射波将传播损失减轻了5-20 dB。射线追踪的结果显示，与FDTD相比，损耗值减小了约5 dB。
Effect of surrounding buildings on large vehicle shadowing in intersection V2V communication has been analyzed by FDTD method. The result of FDTD analysis is compared with that of ray tracing in terms of propagation loss. Although the shadowing of large vehicles issues large attenuation, reflected waves from the buildings mitigate the propagation loss by 5–20 dB. The results of ray tracing show smaller loss values by around 5 dB from that of FDTD.
