Final answer:
The question pertains to the critical role of traffic signals in enhancing pedestrian safety by providing safe crossing times and enforcing speed limits at intersections.
Step-by-step explanation:
The statement pertains to pedestrian safety at an intersection near a campus where students and others frequently cross, facing the danger of dodging traffic. The presence of a traffic signal at such intersections is a crucial measure to ensure pedestrian safety. Traffic signals play a dual role; they not only provide designated times for pedestrians to cross safely but also compel vehicles to adhere to the speed limit, reducing the likelihood of speeding through the intersection. With a traffic signal in place, it establishes a regulated flow of both pedestrian and vehicle traffic, thereby augmenting overall safety and minimizing the risk of accidents.
