Supported by a $25 million TIGER grant, the Truck Parking Information Management System identifies empty parking spaces along interstate highways, then funnels the information to truckers through mobile apps or highway signage.

The project got off the ground a few years ago, when the Mid America Association of State Transportation Officials (MAASTO) applied for the federal grant to create a system that would inform truck drivers in advance of the amount of parking at public rest areas as well as private businesses.  TIGER grants stand for  Transportation Investment Generating Economic Recovery.
