Measurable energy and environmental benefits were reported during the following project.

Deployment of a SCOOT Signal System in Toronto

SCOOT (Split Cycle Offset Optimization Technique) was an adaptive signal control system that quickly updated signal timings to meet the needs of changing traffic volumes and patterns. Toronto conducted a demonstration project to compare SCOOT to fixed (i.e., predetermined) signal timing control plans.

The results indicated adaptive signal control decreased fuel consumption by 4 to 7 percent and reduced harmful emissions by 3 to 6 percent.
