研究发现，在信号交叉口左转和右转对行人的危险比直行要高三到六倍，这主要是因为司机未能观察行人或给行人让路。目的是评估“转弯交通必须让行人”标志，该标志旨在提醒转弯驾车者有法律义务让路给行人，从而减少车辆与行人的冲突。该标志安装在两个城市的 12 个有标记的人行横道上，并在安装前后收集了车辆与行人冲突数据。该标志可有效减少左转冲突 20% 至 65%，右转冲突减少 15% 至 30%；两次降低均达到 0.05 水平，具有统计显着性。该标志在减少左转冲突方面比减少右转冲突更有效。随着行人离开，行人和转弯交通之间的冲突百分比有所下降
Left- and right-turn movements at signalized intersections have been found to be three to six times more hazardous to pedestrians than through movements mainly because drivers fail to observe or yield the right of way to pedestrians. The objective was to evaluate the Turning Traffic Must Yield to Pedestrians sign, which was aimed at reminding turning motorists of their legal obligation to yield the right of way to pedestrians and, consequently, reducing vehicle-pedestrian conflicts. The sign was installed at 12 marked crosswalks in two cities, and vehicle-pedestrian conflict data were collected before and after its installation. The sign was effective in reducing left-turn conflicts 20 to 65 percent and right-turn conflicts 15 to 30 percent; both reductions were statistically significant at the 0.05 level. The sign was significantly more effective in reducing left-turn conflicts than it was for right-turn conflicts. Percentage conflicts between pedestrians and turning traffic decreased as the pedestrian g...
