Final answer:
The question explores the need for installing traffic signals at intersections to address vehicle speeding and pedestrian safety, specifically near campus areas.
Step-by-step explanation:
Making a protected left turn at an intersection without a special turn light involves a traffic scenario where safety and law intersect, which is an element of social studies. There are significant reasons for installing a traffic signal at such an intersection. Vehicle speed is often a concern, as vehicles tend to ignore the posted speed limit and speed through, creating hazardous conditions. The presence of a traffic signal would theoretically enforce speed reduction because drivers would need to adhere to the traffic signal's control, thus slowing down when necessary.
Pedestrian safety is another critical aspect to consider. Students and others who cross at the intersection, especially in high traffic areas near campuses, are put at risk when there is a lack of traffic control. Pedestrians must currently navigate between cars, which is dangerous and could lead to accidents. A correctly timed traffic signal would offer a safe window for pedestrians to cross, thereby improving the overall safety of the intersection.
Focusing on one specific example, the installation of a traffic signal at the intersection of Clay Street and Eagle Avenue resulted in improved safety measures. Prior to the signal installation, the location was notorious for speeding vehicles and pedestrians were at risk. The introduction of the traffic signal has organized traffic flow and provided a safer crossing environment for pedestrians, proving the effectiveness of such measures.
