Final answer:
Installing a traffic signal at a busy intersection is essential for pedestrian safety, managing vehicle speeds, and handling increased traffic volume. It's especially crucial where accident rates are high, indicating a serious threat to public safety that can be mitigated through proper traffic control measures.
Step-by-step explanation:
Improving pedestrian safety is a crucial issue, particularly in areas where there is a significant flow of students and traffic.
Installing a traffic signal is a measure that serves to alleviate safety concerns for a few reasons. The primary benefit of a traffic signal is to manage the speed of vehicles, compelling them to slow down and adhere to speed limits, which enhances safety for pedestrians who need to cross the street.
Furthermore, the volume of traffic at a particular intersection might necessitate the installation of a traffic signal.
If there has been a noticeable increase in traffic due to nearby developments like a manufacturing plant or the expansion of a strip mall, this can lead to a higher incidence of traffic accidents.
In such cases, a traffic signal can effectively regulate the flow of vehicles and provide safe crossing times for pedestrians.
Last but not least, the consideration of accident rates is critical. A high frequency of accidents, especially those resulting in serious injury or loss of life, underscores the urgent need for a traffic control mechanism like a traffic signal to improve road safety for everyone.
