Agencies are frequently challenged with moving traffic in congested conditions and situations where the traffic demand exceeds the capacity of the system. The focus of this workshop is to diagnose types and causes of oversaturated conditions at signalized intersections, identify appropriate operational objectives based on observed conditions and discuss available mitigating strategies that can have an appreciable effect on overall system performance.


Since 2010, the Traffic Signal Academy has provided services to over 1,000 participants in 6 different courses. Federal, state, county and city agencies plus consultant firms have attended our classes.
