Virtual Traffic Lights

next-gen traffic lights powered by AI & state of the art multi-agent reinforcement learning algorithms

trafluid

Real-time, cycle-free, AI-powered adaptive traffic signal control.

State of the art reinforcement learning techniques

Unlike traditional adaptive systems that operate on fixed cycles, Trafluid leverages advanced reinforcement learning to dynamically activate the most efficient signal phase at any moment. By analyzing both real-time and historical traffic data, our AI models learn optimal control strategies and respond instantly to changing conditions across the entire road network. Integrated directly with traffic signal controllers and cabinet equipment, Trafluid ensures every decision is not only efficient but also 100% safe.

Cut Commute Times and Costs with Trafluid

Trafluid reduces commute times by up to 40% compared to fixed-time signals, and by over 10% even when measured against optimized, coordinated systems. Best of all, these performance gains come without the usual price tag: Trafluid is up to 50% more affordable than traditional solutions, thanks to its cloud-based design and hardware efficiency!
