SCOOT Adaptive Control

The World's Leading Adaptive Traffic Control System

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.

Deploying SCOOT in Seattle

Siemens SCOOT is the ASC selected by the Seattle Department of Transportation (SDOT) to improve overall travel times and travel reliability in their busiest corridors. SCOOT determines traffic levels, predicts the flow of traffic, and adjusts the amount of time available to each movement through an intersection. 

 

Based on the successful deployment in June 2017, traffic signal performance measures have reduced travel times an average of 21% along the corridor during the busiest peak hours.

Keeping Traffic Moving in Ann Arbor

In the City of Ann Arbor, traffic is anything but predictable. Its population of 115,000 residents swells to 185,000 when school is in session. On an average weekday, 130,000 commuters come to Ann Arbor for work, while another 40,000 go to work elsewhere. Special events can happen any day, or night, of the week and draw thousands. Football games at Michigan Stadium cans double the number of cars in town.

 

SCOOT reduced weekday travel times in Ann Arbor by 12% and weekend travel times by 21%.

Benefits

  • 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.

  • The Stratos Outstation has a future-proof platform – easily updatable to support new SCOOT functionality.

  • The Stratos Outstation is capable of full implementation of UG405.

  • The Stratos Outstation also has a wide range of NEMA controller and detection technology compatibility.

Features

  • 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.

  • The Stratos Outstation has a fully web-based user interface.
