在多车道高速公路上,小型车辆驾驶员视认路侧交通标志时,视线经常会被外侧车道上大型车辆所遮挡而漏看交通标志,为此建立了基于时间的路侧标志遮挡概率计算模型。与以往模型相比,该模型能够动态地分析大车对标志的遮挡情况,最大程度地还原遮挡发生条件;同时将标志的幅面及设置情况、驾驶员行为、交通流状态等影响因素加入到模型中,更加全面地考虑视线遮挡及漏看标志发生的外部条件。
On the multi-lane expressway, when a small vehicle driver regards the traffic sign on the roadside, the sightline is often overshadowed by the large vehicles on the outer lane to overlook the traffic sign. Therefore, a time-based obstruction probability calculation model of the roadside signage is established . Compared with the previous model, the model can dynamically analyze the obstruction of the sign on the trolley and restore the occlusion conditions to the maximum extent. At the same time, the influence factors such as the amplitude and setting of the sign, driver behavior and traffic flow state are added to the model , More comprehensive consideration of the occlusion of the sight and omission of the external conditions under which the signage occurred.
