Final answer:
Controlled and uncontrolled intersections serve different purposes in managing traffic flow and safety. Four-way stops provide an organized way for vehicles to navigate intersections.
Explanation:
Controlled intersections have traffic lights, yield signs or stop signs to regulate traffic flow and ensure safety. These intersections help prevent accidents and ensure that vehicles and pedestrians can navigate the crossing safely.
Uncontrolled intersections lack these control measures, making them more prone to accidents and confusion among drivers. Implementing traffic signals at busy intersections can significantly enhance safety and traffic flow.
Four-Way Stops are intersections where all vehicles must come to a complete stop, allowing each to proceed in turn. This system helps in managing traffic at intersections with similar priority levels.
