INFORM Operations


INFORM (INformation FOR Motorists) is a corridor traffic management system designed to obtain better utilization of existing highway facilities. INFORM has been implemented in a 50-mile long highway corridor on Long Island, New York  in accordance with a cooperative agreement between the Federal Highway Administration (FHWA), the New York State Department of Transportation (NYSDOT), and the transportation agencies of local governments on Long Island.

The INFORM corridor contains three major limited access roadways, the Long Island Expressway (LIE-Interstate 495), the Northern State Parkway / Grand Central Parkway (NSP/GCP), and the Southern State Parkway, along with a number of parallel and crossing arterial streets and freeways, a total of 128 miles of controlled roadways. The system consists of electronic surveillance, communications, signing and control components, traveler information for warning and route diversion, ramp control and signal control.

DEA personnel played instrumental roles in conceiving, designing, implementing and now operating INFORM. DEA participated in the overall evaluation of INFORM, lessons learned, and establishment of guidelines to be used in the design, operation and evaluation of similar systems.  DEA, in association with Parsons Brinckerhoff, now operates INFORM for New York State.
