A traffic signal is a control device that assigns right of way among road users at an intersection or crossing. A project may include warrants or justification studies, design, equipment, timing, and agency approvals. Requirements vary by jurisdiction. Engineering review addresses the specific site and applicable standards, with operation and maintenance managed under assigned responsibilities.
Why it matters for owners
Signal projects involve design, power, communications, and agency interfaces. Define deliverables and approval paths in the scope.
