A model that predicts how long it will take a group of pedestrians to cross a busy intersection, for example, generally fails to reconstruct the chaos seen when people try to escape a crowded room.
例如,一个预测行人过繁忙的十字路口要用多长时间的模型,通常都不能重现人们拼命逃离拥挤房间的混乱景象。
Watch for pedestrians about to cross the intersection and vehicles edging into the intersection or approaching at higher speeds.
注意横穿路口的行人,以及低速进入路口或是高速靠近路口的车辆。
