A Signal Timing Plan is a strategy used to control traffic signals at intersections. It determines how long each signal light stays green, yellow, or red, optimizing traffic flow and reducing congestion. This plan considers factors like traffic volume, pedestrian needs, and safety to ensure efficient movement for vehicles and pedestrians. The effectiveness of a Signal Timing Plan can be enhanced by using technology such as traffic sensors and adaptive signal control systems. These tools help adjust signal timings in real-time based on current traffic conditions, improving overall traffic management and reducing wait times at intersections.
