| 摘 要： | 高速公路和城市快速路通常将内侧车道设置为小车道,外侧车道设置为大车道,这将有可能导致内侧小车驾驶员视线被遮挡,无法及时获得路侧交通标志的信息采取相应的措施,从而引发交通事故。通过对驾驶员对路侧交通标志视认过程的分析,提出了计算单个路侧交通标志被遮挡概率的计算方法,并运用概率论的知识建立了求解连续多个路侧交通标志设置数量的数学模型和标志设置位置的计算公式,提出了路侧交通标志设置的具体步骤。通过计算示例证明理论模型及算法实用可行。

| Abstract: | For intercity and urban expressways there are lanes usually divided for different vehicles,with offside lane for cars and nearside lane for trucks.This may made the drivers of the cars can't see road side traffic signs,which may cause traffic accidents.On the base of analyzing the recognizing process of road side traffic signs,the method to calculate the probability of the individual road side traffic sign being blocked off is put forward.The mathematical models of road side traffic signs' setting amount and position are proposed,including the traffic sign development program.The demonstration results show that those models and theory are feasible. |
