The American Association of Airport Executives (AAAE) and San Francisco International Airport (SFO) have announced the establishment of a system that tracks app-based ground transportation (ABT) transactions in the airport environment within a designated GPS "geo-fence" area for fee calculation, roadway planning, and facility improvement efforts. AAAE will be providing this service under contract with SFO for Uber, Lyft, Sidecar and other ABT providers. The system was developed by SFO and licensed through AAAE for use at airports across the country. "AAAE delivers service, innovation and results for our members," AAAE President and CEO Todd Hauptli stated. "We congratulate San Francisco on its groundbreaking efforts with app-based transportation companies and we are proud to bring this elegant revenue tracking solution to airports all across the country." He continued, "This is a win-win approach for airports to prevent continued revenue leakage and for users and providers of app-based ground transportation services." "We are proud to be an industry leader, by creating a solution for tracking app-based ground transportation," said SFO Airport Director John L. Martin. "We appreciate the partnership with the AAAE to make this system available to airports across the United States."
