Final answer:
To mitigate risk at an intersection crowded with vehicles and a pedestrian, the implementation of a traffic signal can enhance safety by controlling vehicle speeds and providing safer crossing for pedestrians.
Step-by-step explanation:
The presence of four vehicles and a pedestrian approaching an intersection at the same time might represent a situation to mitigate the risk (and move forward to an alternative maneuver at a different intersection) of completing the maneuver. This is particularly important considering pedestrian safety, as crowded intersections near campuses can be dangerous for students and others trying to cross. The installation of a traffic signal at problematic intersections can regulate vehicle speeds, enforce stopping at red lights, and provide safe crossing for pedestrians.
Indeed, without proper signals, vehicles often disregard speed limits, and pedestrians are forced to navigate through traffic, which increases the possibility of accidents. These accidents can have serious consequences, including fatalities. Therefore, the implementation of a traffic signal can significantly enhance safety by controlling traffic flow and providing predictable crossing periods for pedestrians.
