Status: Completed
We want you to have an exceptional customer experience in the Seattle-Tacoma International Airport (SEA) parking garage. SEA incorporated new technology and installed the Park Assist® automated parking guidance system (APGS) to solve many customer parking issues once inside the garage.
Elevating Efficiency and Safety
With over 12,000 stalls spread across eight floors in the parking garage, finding an open stall quickly can be a challenge. With the Park Assist APGS, parkers can find an open stall quickly using a system of wayfinding signage, smart sensors and LED lights to designate available or occupied stalls. Sensors and lighting were installed above all drive lanes in the garage to help you navigate the parking garage more efficiently. Each sensor also comes equipped with camera-based license plate recognition (LPR) technology to assist our Operations staff with parking policy enforcement (ex. restricted, premium stalls, overstays) and help locate your vehicle in case you forget where you parked, and motion-activated video surveillance to improve vehicle monitoring and security in the garage.
Getting Greener
We heard your feedback regarding the lack of EV stalls and we understand that the number of electric vehicles in the region is continuously rising. The APGS project increased our EV charging capacity in the garage by nearly 50%, expanding the number and charging speed of electrical charging stations to meet public demand.
Previously, there were 48 Level 1 public parking charging receptacles in the garage that were consistently occupied. This project has nearly doubled the number of EV charging stations to 94 stalls and improved the vehicle charging capacity with the addition of new Level 2 chargers (120V vs 240V power supply). There is the opportunity for further EV stall expansion should future demand require it. This improves the customer service for plug-in vehicle drivers, while also reducing emissions from ground transportation.
Construction
Our partner for this project, PCL Construction, began installation of the system in March 2021; construction was completed in December 2024. PCL installed the electrical infrastructure, APGS equipment and the electric vehicle charging equipment.
Estimated Project Costs
The APGS project is estimated to cost $22.9 million.
