Final answer:
The need for a traffic signal at an intersection is highlighted by the tendency of vehicles to speed, the safety concerns for pedestrians, and the high rate of traffic accidents, some of which have been fatal.
Step-by-step explanation:
The discussion around the installation of a traffic signal at an intersection involves several important factors. First, it is clear that the lack of a signal allows many vehicles to speed through the intersection without adherence to the posted speed limits. Consequently, a traffic signal would act as a deterrent, compelling vehicles to slow down and preventing them from speeding through.
Moreover, pedestrian safety is a significant concern. The intersection in question is frequented by students and others who face difficulties safely crossing due to the traffic. Introducing a traffic signal would enable pedestrians to cross at designated times, significantly enhancing their safety.
Additionally, the sharp increase in traffic accidents, including those resulting in fatalities, underscores the urgent need for a traffic signal. Data from police reports indicate that the intersection is the site of frequent accidents, with at least three occurring every month. This rising accident rate provides a compelling argument for the installation of a traffic regulation device.
