Final answer:
Considering the increased vehicle speeds, pedestrian traffic, and accident rates, the installation of a traffic signal is justified for improved road and pedestrian safety.
Step-by-step explanation:
When approaching the decision to install a traffic signal at an intersection, several factors must be considered to ensure both vehicle and pedestrian safety. The reasons to support such an installation are multifold: firstly, to regulate the speed of vehicles that tend to ignore the posted speed limit, thus compelling them to slow down. Secondly, the safety of pedestrians, especially in areas frequented by students and campus visitors, must be taken into account since a traffic signal can aid them in crossing at appropriate times, reducing the need to navigate through fast-moving vehicles.
Additionally, the overall traffic has increased due to new developments such as manufacturing plants and business expansions. This rise in traffic volume further warrants the introduction of a traffic control measure. Most importantly, the increase in traffic accidents, including those resulting in the loss of life, underscores the urgent need for a traffic signal to mitigate these risks.
