In modern cities, traffic signal systems are essential tools for managing the flow of vehicles and pedestrians. These systems are designed to regulate the movement of traffic, ensuring safety and reducing congestion on busy streets. By using traffic lights, urban planners can optimize travel times and prevent accidents.

Key Components of Traffic Signal Systems:

  • Signal controllers
  • Traffic detection systems
  • Signal poles and lights
  • Pedestrian push buttons

Types of Traffic Signal Phases:

  1. Red: Stops all traffic.
  2. Green: Allows vehicles to move.
  3. Yellow: Warns vehicles to prepare to stop.

"Proper synchronization and timing of traffic signals can reduce traffic delays by up to 25%."

Signal Control Methods:

Method Description
Fixed Time Control Signals change based on preset intervals regardless of traffic volume.
Adaptive Control Signals adjust dynamically based on real-time traffic flow and demand.
