SCOOT Adaptive Control Software
SCOOT, which represents 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.
Continuously Measure Traffic Demand
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 Traffic Model
The heart of SCOOT is a traffic model that predicts a short-term traffic demand. SCOOT uses this model to predict the effect of small changes to the current timing of signals. The SCOOT traffic model is based on data collected from presence detectors at the rate of once per second on each link to the network.
This data is processed, then updates the cyclic flow profiles - one for each link. The traffic flow model contains a representation of traffic demand at the stop line.
Results of implementing a SCOOT system include reduced travel time and driver delay, improvements in air quality, lower fuel consumption, and savings on planning time.
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
