Urban intersections increasingly rely on advanced signaling systems that operate using microcontrollers and light-emitting diodes. These systems ensure accurate vehicle flow control, adaptive timing, and real-time status monitoring through programmable logic.
- Microcontrollers execute predefined timing algorithms
- LEDs provide energy-efficient and high-visibility indicators
- Sensors enable dynamic traffic response
Smart signaling units reduce intersection delays by up to 30% during peak hours.
To manage multi-directional vehicle movement, the system incorporates a cycle-based logic sequence. Each phase of the cycle is assigned specific time values, ensuring structured transitions between stop, ready, and go signals.
- Phase 1 – Halt signal activated (red)
- Phase 2 – Prepare to move (yellow)
- Phase 3 – Passage granted (green)
| Signal | LED Color | Duration (seconds) |
|---|---|---|
| Stop | Red | 30 |
| Ready | Yellow | 5 |
| Go | Green | 25 |
A programmable LED system supports adjustments for emergency vehicles and pedestrian crossings in real time.
