The purpose of this experiment was to evaluate the effects of signs reading "STOP HERE FOR PEDESTRIANS" alone and in conjunction with advance stop lines on pedestrian safety at multilane crosswalks with pedestrian-activated amber flashing lights. Motorist and pedestrian behaviors measured throughout this experiment included the occurrence of various types of motor vehicle-pedestrian conflicts; the distance that motorists stopped before the crosswalk when yielding to pedestrians; and the percentage of motorists yielding to pedestrians. The introduction of the sign alone 50 feet (15.15 m) before the crosswalk increased the distance before the crosswalk that motorists yielded to pedestrians and reduced the percentage of motor vehicle-pedestrian conflicts whether the flashing light was activated or not. The addition of the advance stop line was associated with further improvements in both measures.
本实验的目的是评估“行人在此处止步”标识单独使用以及与提前停止线结合使用时，对设有行人触发式琥珀色闪烁灯的多车道人行横道上行人安全的影响。在整个实验过程中测量的机动车驾驶员和行人行为包括各类机动车与行人冲突的发生情况；驾驶员在人行横道前让行行人时停车的距离；以及驾驶员让行行人的比例。在人行横道前50英尺（15.15米）处单独设置该标识，无论闪烁灯是否启动，都增加了驾驶员在人行横道前让行行人的距离，并减少了机动车与行人冲突的比例。增设提前停止线使这两项指标都得到了进一步改善。
