| 摘 要： | 为解决大型车对路侧交通标志的遮挡问题,针对普通公路大型车比例较高的特征,分析了我国常见的双向4车道普通公路外侧车道行驶的大型车遮挡内侧车道行驶的小型车驾驶员视认路侧交通标志的过程,推导了视认过程中的遮挡长度和遮挡概率的计算公式,设计了确定路侧交通标志重复设置次数的计算流程,建立了路侧交通标志重复设置间距的计算模型,并用算例进行了验证.结果表明:重复设置一次后,两块限速标志都被大型车遮挡的概率为0.023；路侧交通标志重复设置的最佳间距为155 m.

| Abstract: | Heavy vehicles account for a large proportion on ordinary highways.In order to solve the occlusion problem that heavy vehicles shelter roadside traffic signs,an analysis was made for the sign recognition process of car drivers at the median lane being occluded by heavy vehicles at the outside lane on an ordinary bidirectional highway with 2 lanes in each direction,and the calculation formulas for occlusion length and occlusion probability in the sign recognition process was derived.Then,the calculation flow... |
