Final answer:
The installation of a traffic signal at a high-traffic intersection is advocated to improve pedestrian safety and control vehicle speed. Without the signal, pedestrians, including students, face danger crossing the street, and vehicles tend to ignore speed limits, leading to increased accidents.
Step-by-step explanation:
The question concerns the need for a traffic signal at a particular intersection, primarily to enhance pedestrian safety and regulate vehicle speed. This traffic signal is particularly advocated for because of the risk presented to pedestrians, many of whom are students, who have to navigate traffic when arriving at or leaving campus. A traffic signal installation would enable these pedestrians to cross roads at designated times, without risking their lives dodging speeding vehicles.
Furthermore, the installation of a traffic signal at this intersection would mitigate the issue of vehicles speeding through without regard for the posted speed limits. It has been noted that the absence of a traffic signal encourages such behavior, resulting in an increase in the number of accidents, potentially leading to injuries or even fatalities.
Concerns about road safety extend to areas around tollbooth stations, where measures such as wires in the pavement are put in place to interact with approaching vehicles. These are used for various purposes, including toll collection, vehicle counting, or ensuring vehicles slow down as they approach the tollbooth.
