Adaptive Traffic Signal Control
What is Adaptive Traffic Signal Control?
Adaptive traffic signals detect and respond to real-time travel conditions. Cameras are used to detect the size of queues waiting for a signal, and a central "brain" uses this information to decrease your wait and ensure efficient timing for vehicles all the way down the corridor. Alexandria's current traffic signal system works like a programmable thermostat, changing the traffic signals according to the time of day. This project will help the city better respond to unexpected disruptions, and empower a smoother travel experience for drivers, buses, and emergency vehicles.
The Adaptive Traffic Signal Control (Adaptive) project will:
- Upgrade traffic signal software
- Implement new traffic signal controllers for consistent infrastructure Citywide and to integrate with future autonomous vehicles
- Deploy vehicle sensors to allow traffic signals to adapt to changing traffic conditions.
