Final answer:
Key factors for installing a traffic signal include managing vehicle speed, enhancing pedestrian safety, and reducing the number of accidents. A traffic signal compels vehicles to slow down, gives pedestrians safe crossing times, and can decrease the frequency of traffic collisions.
Step-by-step explanation:
Reasons for Installing a Traffic Signal
When considering the installation of a traffic signal at an intersection, several factors are taken into account. Vehicle speed through the intersection is an important concern, especially when drivers ignore the posted speed limit, which can lead to dangerous conditions. The installation of a traffic signal often becomes necessary as it ensures vehicles slow down, making the intersection safer.
Another crucial factor is pedestrian safety. In areas with heavy foot traffic, such as near a campus, pedestrians may be forced to navigate through cars, putting themselves at risk. A traffic signal provides structured crossing times, greatly increasing the safety for those on foot.
Finally, an increase in the number of accidents at an intersection, sometimes with tragic outcomes, is a compelling reason to install a traffic signal. The installation of the signal would significantly reduce the risk of accidents, as evidenced by traffic studies and police reports indicating frequent collisions.
