Final answer:
Caution, clear, and danger signals are meant for drivers, pedestrians, and cyclists to ensure road safety, manage speeds, and prevent accidents.
Step-by-step explanation:
The caution, clear, and danger signals are displayed for the information of all road users, which include drivers, pedestrians, and cyclists. Traffic signals play a critical role in ensuring the safety of everyone on the road. They help in managing vehicle speeds and providing safe crossing opportunities for pedestrians. Specifically, the installation of a traffic signal can make a significant impact on pedestrian safety around busy intersections, such as those near campuses, where individuals often need to navigate through traffic. A proper understanding of traffic signals and road signs is crucial for avoiding accidents and ensuring a safe environment for all.
For instance, a traffic signal encourages vehicles to slow down instead of speeding through intersections, thereby reducing the chances of accidents. The presence of these signals is a direct response to safety concerns, including the troubling trend of accidents, some of which may result in tragic outcomes such as loss of life.
