Intelligent Intersection Traffic Control Laboratory Fact Sheet
PDF version of Fact Sheet (272 KB)
The Intelligent Intersection Traffic Control Laboratory (IITCL) is an outdoor facility that supports the Federal Highway Administration's (FHWA) various research programs and research activities conducted by other U.S. Department of Transportation (USDOT) agencies. This includes USDOT's two major intelligent transportation system (ITS) programs: the Cooperative Intersection Collision Avoidance Systems (CICAS) initiative and the Vehicle Infrastructure Integration (VII) initiative. The IITCL serves as a testing ground for intersection-related research projects and as a place to integrate and demonstrate advanced technologies. Since its inception, many successful demonstrations and research activities have been conducted at the IITCL.
The IITCL is equipped with the most advanced technologies in the ITS and traffic control industries. For example, the IITCL features a comprehensive traffic signal control system, a dedicated short-range communication (DSRC) system, an advanced system for the detection of vehicles and pedestrians, a fiber-optic communication system, a CICAS driver infrastructure interface (DII) warning system, and a separate traffic signal cabinet with various computers and communication devices. The DSRC system can provide 5.8 and 5.9 gigahertz communication capacity to test vehicles equipped with DSRC onboard units.
The fiber-optic communication lines can transmit live videos and real-time data to central computers located in FHWA's Traffic Research Laboratory (TReL). FHWA also installed two DIIs with light-emitting diodes at IITCL for research and technology demonstrations. These technologies enable researchers to conduct numerous traffic engineering, human factors, traffic safety, pedestrian safety, collision avoidance, simulation, and other technology studies.
PRODUCTS AND SERVICES
IITCL combines the expertise of systems engineering, traffic engineering, communications, data acquisition and processing, and intersection-related ITS operations.
