The Northern Illinois Transit Authority (NITA), formerly the Regional Transportation Authority, was created by the Illinois General Assembly and Governor JB Pritzker to make transit across northeastern Illinois work for riders as one regional transit system. 

NITA sets regional fares, service standards, and schedules across the Chicago Transit Authority (CTA), Metra, and Pace; plans and funds transit investment; and oversees system performance and finances. Across the six-county region, the transit system provides more than 1.3 million rides a day.
