The INFORM (INformation FOR Motorists) system was one of the Nations first and is one of the largest and most advanced transportation management and information systems in the country.

INFORM covers Long Island's Northern and Southern corridors, consisting of the island's major east-west highways and their busiest north-south connecting routes, including the Long Island Expressway (LIE/I-495), Northern State Parkway (NSP) and Southern State Parkway (SSP).

INFORM operates 24 hours a day, 365 days a year from the Transportation Management Facility located in Hauppauge, NY.
