Final answer:
The purpose of traffic signs, particularly traffic signals, is to regulate the flow of traffic, improve pedestrian safety, and provide essential information to prevent accidents. The installation of such signals is vital especially in high-risk intersections to reduce speeding and facilitate safer pedestrian crossing.
Step-by-step explanation:
The purpose of traffic signs is to ensure the safety of drivers, pedestrians, and cyclists by regulating the flow of traffic and providing essential information. Traffic signals, in particular, play a pivotal role in enhancing road safety. When installed at crucial intersections, they can significantly reduce the likelihood of vehicular speeding and potential accidents. For instance, a traffic signal at the intersection of Clay Street and Eagle Avenue was necessary because many vehicles disregarded the posted speed limit, jeopardizing pedestrian safety. Students and others needed to cross to and from campus but were forced to navigate through constant and dangerous traffic. The compelling need for a traffic signal was underscored by an alarming number of accidents, with police reports indicating at least three traffic accidents a month, including one that tragically resulted in a loss of life.
Furthermore, pedestrian safety is greatly improved with the presence of a traffic signal. It provides a structured opportunity for pedestrians to cross intersections safely and could potentially lower the risk of accidents. Lastly, traffic signals aid in the interpretation of road signs, many of which are universal, but still require additional cues, such as signals, for correct interpretation and action by drivers and pedestrians alike.
