The Passenger TSI, which measures the volume of for-hire passenger services in the United States, fell 123 points from February to April of 2020, and recovered only 42 points by January 2021.
The Passenger TSI includes local mass transit, intercity passenger rail, and passenger air transportation. The Freight TSI includes for-hire trucking, freight railroad services, inland waterway traffic, pipeline movements, and air freight.
