We want you to have an exceptional customer experience at the Seattle-Tacoma International Airport (SEA) parking garage. SEA is incorporating new technology and installing 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 Seattle-Tacoma International Airport (SEA) garage, finding an open stall quickly can be a challenge. With the Park Assist APGS, parkers will be able to 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 will be 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.
Transitioning to Pre-Booked Parking and Variable Pricing
Installing the APGS comes with the additional benefit of being able to better transition the garage to be a mostly pre-booked parking facility. The goal is that when you pre-book, you will have a guaranteed stall in a designated location within the garage and the APGS smart sensors will assist with that. With this system, we will also be able to offer a variable pricing model that will allow SEA to offer lower pricing during times of low occupancy.
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 will increase our EV charging capacity in the garage by nearly 50%, expanding the number and charging speed of electrical charging stations to meet public demand.
Currently, there are 48 Level 1 public parking charging receptacles in the garage that are consistently occupied. This project will nearly double the number of EV charging stations to 94 stalls, as well as provide the capability to double the vehicle charging capacity (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 Phase: In Progress
Our partner for this project, PCL Construction, began installation of the system in March 2021. PCL is installing the electrical infrastructure, APGS equipment and the electric vehicle charging equipment.
The phased construction will temporarily close parts of the garage to parkers. Currently the parking closures include select areas on floors 1, 2 and 4. We estimate that 700-1,000 stalls may be unavailable at a given time.
