The objective of this research is to update ACRP Research Report 215: Transportation Network Companies (TNCs): Impacts to Airport Revenues and Operations to reflect the latest trends and practice. The report should include an overview of historic activity and future trends and guidelines to help practitioners plan for and manage TNC operations at their airports. The guidelines should help practitioners consider the following factors for TNC operations at airports and overall landside operations: Airport revenue, including fee setting and collection mechanisms, impact on other revenue sources, and protecting future airport revenues; Effect of TNCs on airport facilities, operations, airport congestion, and transportation demand management; State and local legislation, or airport rules and business practices relevant to ground transportation; Emerging technologies (e.g., autonomous vehicles, robo-taxis, ground transportation virtual queuing); Passenger experience and convenience (e.g., wayfinding, passenger dwell time, affordability); and Accessibility for travelers with mobility challenges. The report should include an executive summary and representative examples of best practices of TNC operations at airports of various sizes and passenger profiles.
