Minimizing traffic delays and stops with SCOOT Adaptive Control 

The City of Monterey, CA, a small town of 28,000 people, uses Siemens Mobility SCOOT adaptive control to keep traffic flowing as it handles as many as 5 million tourists each year.

Siemens Mobility SCOOT is the world's leading adaptive traffic control system. 

A dynamic, online, real-time method of signal control, it continuously measures traffic demand on all approaches to intersections in a network. SCOOT (Split Cycle Offset Optimization Technique) then uses this information to optimize the signal timings at each intersection in order to minimize delays and stops. Timing changes are small, to avoid major disruption to traffic flows, and frequent, to allow rapid response to changing traffic conditions. SCOOT is fully responsive to varying traffic flow conditions, such as sporting events and incidents, and is suitable for implementation on all types of urban roads, grids, corridors, and arteries. 


Comparison to Other Adaptive Systems

Other than adding capacity through roadway construction, implementing adaptive signal control is the single most effective strategy for reducing traffic congestion. Siemens Mobility SCOOT is the most proven, most widely deployed, and the most effective adaptive system in the world. This is shown by the successful deployment of over 125 SCOOT systems comprising over 7000 intersections over a 30-year period.

SCOOT is more far effective that other adaptive systems for several important reasons:

Deploying SCOOT in Seattle

Siemens Mobility SCOOT is the adaptive control system selected by the Seattle Department of Transportation (SDOT) to improve overall travel times and travel reliability in its busiest corridors.


SCOOT measures  traffic volumes,  predicts the flow of traffic and optimizes the amount of green time available for each movement through an intersection. Based on the successful deployment of SCOOT in June 2017, traffic signal performance measures have reduced travel times an average of 21% during the business peak hours along its Mercer Corridor, a critical artery serving a growing technology hub.

Keeping Traffic Moving in Ann Arbor

In the City of Ann Arbor, MI, 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 of people. 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%.
