Traffic Signal Operations and Maintenance

Traffic volumes on signalized arterial roadways are ever changing. It is critical to have signal systems operating effectively and efficiently to serve this changing demand. Signal timing is a cost-effective approach to improving mobility, reducing delays, and improving corridor safety.

Alliant staff have diverse and extensive experience in traffic signal operations including coordinated timing plan development, controller programming, field implementation and fine-tuning, traffic operations analysis, and traffic simulation and modeling. We use this experience to complete major signal projects nationally and throughout the Midwest.
