Traffic signal design

Traffic signal design involves creating a system of lights that manages vehicle and pedestrian movement efficiently and safely at intersections. It considers factors like traffic flow volume, road layout, and safety requirements to determine light timing, placement, and coordination. Proper design ensures minimal congestion, reduces accidents, and allows smooth transition between different directions and modes of travel. Engineers also account for visibility, environmental conditions, and pedestrian needs, using standards and data to optimize signal operation. Well-designed signals balance efficiency and safety, guiding traffic predictably and reducing conflicts or delays.
