Final answer:
The question focuses on pedestrian safety at intersections and the benefit of having traffic signals to regulate both pedestrian and vehicle movement. Traffic signals help in making pedestrians crossing safer by giving them the opportunity to cross at appropriate times and make drivers slow down. Pedestrians must also plan their route and timing carefully to ensure safety and punctuality.
Step-by-step explanation:
The question relates to the importance of pedestrian safety and the role of traffic signals in promoting it. When there is an ambulance or any emergency vehicle, a pedestrian should stop moving and become stationary till it passes by, rather than trying to run toward or alongside the ambulance. This ensures your own safety and doesn't obstruct the emergency vehicle. Moreover, the presence of a traffic signal can be very beneficial at busy intersections near places like schools or campuses. It makes crossing the street safer as it regulates traffic and provides appropriate times for pedestrians to cross.
A traffic signal also compels vehicles to slow down, adhering to the posted speed limits, and prevents them from speeding through the intersection. This would significantly reduce the risks for both pedestrians and drivers. Planning your route in advance and allowing extra time for potential delays, as exemplified in the heuristic of working backwards, helps in reaching destinations on time and safely. The same principle is applicable when preparing for important events or a first day at work.
