Flashing Yellow Arrow Intelligent Transportation Systems

KAI conducted traffic operations and safety analyses for over 30 intersections in Alaska's Central Region, identifying for signal enhancements (including conversion to Flashing Yellow Arrow (FYA) indications), signal interconnect (wireless), and new signal poles.

KAI brings national experience with FYA implementation, including criteria for preferred operations to balance vehicle delay reductions with enhanced vehicle and pedestrian safety. Project deliverables include a technical report with site operations and safety review analysis, along with recommendations for implementation location and operational strategies (e.g. control FYA by time of day, gaps detected, or pedestrian presence).
