SCOOT / STRATOS Outstation

SCOOT is the World's Leading Adaptive Traffic Control System.

SCOOT / Stratos Outstation

SCOOT is a dynamic, on-line, real-time method of signal control that continuously measures traffic demand on all approaches to intersections in a network and optimizes the signal timings at each intersection to minimize delay and stops. Timing changes are small, to avoid major disruption to traffic flows, and frequent, to allow rapid response to changing traffic conditions.


  • SCOOT, which is an acronym for Split Cycle and Offset Optimization Technique, is a dynamic, on-line, real-time method of signal control.

  • Optimization of the network is achieved using small, regular changes designed to avoid major disturbance of traffic flow.

  • Cycle Split and Offset are all optimized.

  • Performance indexes (stops and delays) are used to measure effectiveness similar to TRANSYT.

  • Update your signal timing plans every 3 seconds.

  • A proven strategy for ‘Hot Spot’ Traffic Control that can be implemented on a selected basis. SCOOT uses a flexible coordination plan that will expand or contract to match the latest traffic conditions.

  • SCOOT makes an ideal complement to standard Time of Day and Traffic Responsive based traffic control.


  • Fully responsive to varying traffic flow conditions, i.e., sporting events and incidents.

  • Suitable for implementation on all types of urban roads, grids, corridors, and arteries.

  • Easy-to-use window style graphical user interfaces.

  • Can be added to existing Urban or Freeway Traffic Management Systems or provided as part of a complete traffic management system.
