• Description:
  The report details the work performed by the New York City Department of Transportation (NYCDOT) and TransCore ITS LLC. to design and deploy low power and low voltage traffic controller cabinets using 48 VDC technology. Theoretically, the 48VDC devices should offer a power savings at each signalized intersection, which extrapolated over the approximately 14,000 intersections in NYC should be quite significant. In addition, the low voltage field wiring should make the overall maintenance on the traffic signals safer for the technicians. The cabinet design would leverage 48 VDC devices defined in the Advanced Transportation Controller Cabinet standards (ATCC Standards: ITE-5301) with modifications to support the data rates used in the existing traffic controller. The original plan was to deploy these cabinets at ten locations in Long Island City, New York and perform a before after study on the overall power draw. Throughout the process of the cabinet shop testing, the team determined multiple design mismatches between the power draw of the 48VDC signal and pedestrian heads and the rated power outputs of the ATCC standard devices. These issues prevented the NYCDOT from certifying the cabinets as safe for field deployment at this time. NYCDOT created a simulated field environment in their shop to collect data on the cabinet power draw for the study. The NYCDOT is continuing to work with both the cabinet and signal head vendors to address the issues and be able to field install the cabinets at some point in the future.
