Fixed-Time Traffic Signal: This type of signal works on a fixed cycle, regardless of the traffic volume.
Actuated Traffic Signal: This type of signal detects the presence of vehicles and pedestrians and adjusts the signal timing accordingly.
Adaptive Traffic Signal: This type of signal uses real-time traffic data to adjust signal timings and optimize traffic flow.
Coordinated Traffic Signal: This type of signal is synchronized with neighboring traffic signals to allow traffic to flow smoothly along a corridor.
Intelligent Traffic Signal: This type of signal incorporates advanced technologies like artificial intelligence and machine learning to optimize traffic flow and reduce congestion.
Pedestrian-activated Traffic Signal: This type of signal allows pedestrians to request a crossing by pressing a button.
Bicycle-activated Traffic Signal: This type of signal detects the presence of bicycles and adjusts signal timing accordingly.
Transit Priority Traffic Signal: This type of signal is designed to give priority to public transit vehicles like buses and trains.
Emergency Vehicle Traffic Signal: This type of signal is activated by emergency vehicles to clear traffic ahead of them.
HAWK Signal: This type of signal is used to provide safe pedestrian crossings on busy highways.
- "Traffic engineers use signal timing to distribute right-of-way at a signalized intersection."
- "Signal timing involves deciding how much green time the traffic signal provides an intersection by movement or approach (depending on the lane configuration), how long the pedestrian WALK signal should be, whether trains or buses should be prioritized, and numerous other factors."
- "The process includes selecting appropriate values for timing, which are implemented in specialized traffic signal controllers."
