Final answer:
A traffic signal was installed to improve safety at an intersection near a campus where vehicles sped through and pedestrians had high risks when crossing, leading to an increased number of accidents, one being fatal.
Step-by-step explanation:
A traffic signal is an important safety feature for road crossings, particularly in areas with high pedestrian traffic such as near campuses. Installing a traffic signal serves multiple purposes: it forces vehicles to slow down, it allows pedestrians to cross at designated times, and it can significantly reduce the number of accidents. For instance, at the intersection of Clay Street and Eagle Avenue, where there was an increase in accidents including one that resulted in a loss of life, the introduction of a traffic signal was essential. This measure followed the cause-and-effect reasoning that an increased traffic signal was warranted because vehicles sped, pedestrians had to dodge traffic, and accidents increased.
Moreover, factors such as a new manufacturing plant and an increase in nearby businesses, alongside changes in traffic routing for events, have all contributed to an increased traffic load, further compounding the urgency for a traffic signal to ensure safety for all road users.
