Final answer:
The installation of a traffic signal at a sign-free intersection would improve traffic flow rate, enhance pedestrian safety, and reduce the number of accidents.
Step-by-step explanation:
The installation of a traffic signal at a sign-free intersection would have a significant impact on the traffic flow rate. Without signs, vehicles tend to speed through the intersection, disregarding the posted speed limit. However, with a traffic signal in place, vehicles would be required to slow down and stop when necessary, resulting in a more controlled and regulated traffic flow. Additionally, a traffic signal would improve pedestrian safety by providing designated times for crossing the intersection, reducing the need for pedestrians to dodge traffic.
Furthermore, the number of accidents at the intersection is likely to decrease with the installation of a traffic signal. Reports indicate that there have been frequent accidents at the intersection, with some resulting in fatalities. By implementing a traffic signal, it would help mitigate the risks of accidents and potentially save lives.
