The WSDOT’s Northwest Region operates a Traffic Management Center (TMC) in its regional headquarters in north Seattle. This center manages the freeway systems in the central Puget Sound by controlling ramp meters, identifying incidents with closed-circuit televisions cameras, and informing the traveling public in real time. With this effort, the Pacific Northwest Transportation Consortium (PacTrans) and WSDOT are cooperatively providing professional experience, training, and research opportunities to students from the UW’s Department of Civil and Environmental Engineering at WSDOT’s TMC. Under the supervision of WSDOT engineers, students operate the region’s intelligent transportation system and perform various tasks such as identifying congestion and other problems that affect the operation of the Seattle area freeway system, operating high profile systems such as the I-405 Express Toll Lanes and SR 167 HOT Lanes, and managing centralized traffic signal control, variable messages signs, and ramp meter optimization. This arrangement helps WSDOT reliably staff the TMC without increasing costs while also helping UW students prepare for a future in transportation engineering.
