Surtrac Smart Traffic Signals

Using Artificial Intelligence to Reimagine Traffic Control

Surtrac - Real-time Adaptive Traffic Signal Control

  • Real-time Response to Actual Traffic
    Surtrac optimizes every second based on actual traffic flows

  • Decentralized & Inherently Scalable
    Surtrac is decentralized and scalable to networks of any size & shape

  • Optimized for Complex Grids, Not Just Corridors
    While Surtrac is capable of handling suburban corridors with a single dominant flow, it really shines when optimizing more complex grid networks with multiple competing flows that change throughout the day

  • Multi-modal Optimization
    With advanced sensing, Surtrac can integrate vehicle, pedestrian, bus, and bicycle traffic flows according to pre-specified priorities

Surtrac

Intelligent Traffic Signal Control

Surtrac is the most advanced traffic signal control system on the market today. Using patented technology developed in the Robotics Institute and Traffic21 Labs at Carnegie Mellon University, Surtrac combines cutting-edge research in artificial intelligence and traffic theory.

  • Travel Time
    Reduced 25% by eliminating stops and reducing wait time, not just by increasing travel speeds which can negatively impact safety.
  • Delay
    Over 40% less time waiting at intersections.
  • Stops
    30-40% fewer stops, means less wear and tear on roads and tires translating into direct cost savings for drivers and cities.
  • Emissions
    By reducing stops and idling, vehicles produce fewer harmful emissions which improves air quality.

Phaenon Urban Analytics Technology

The Phaenon urban analytics system is designed specifically for cities, where measuring mobility is more than just measuring speed and travel time. Because we have developed the Phaenon sensor to be inexpensive enough for dense, urban deployments, Phaenon provides measurement of cruising for parking, network-level traffic signal performance, traffic congestion, and many other applications that can help improve quality of life.

  1. Sense vehicles, pedestrians, bikes, and transit to build a real-time model of travelers and where they are headed
  2. Every second, optimize over this model to build a Plan of how to best move travelers through the intersection
  3. Communicate with neighboring intersections to coordinate traffic flow in real-time
  4. Act to control the state of the traffic signals at the intersection
