Green traffic controller cabinet

The objective of the program is to reduce the power consumption of NYC traffic control equipment and to improve the quality of the intersection operation monitoring such that it can provide more reliable and sustainable operation. It is estimated that the power consumption of the intersection – which includes the signal heads and the controller and cabinet could be reduced from 30-50% which could result in operational savings of more than $1M per year and a reduction of more than 10 MWh per year in power consumption. However, to take advantage of these types of savings, the cabinet design must be altered to use lower power devices and improved monitoring. In addition, with the available LED signal heads, it is now possible to consider an entire intersection design that operates at 48 Volts or less – which is more typical of the telephone line operation – and hence can be serviced by technicians which has the potential to make repairs more efficient since the same staff that troubleshoot the electronic equipment can now service the traffic controllers.TransCore will work with the New York City DOT and one or more vendors and the standards development organizations to develop and deploy a “green” traffic controller which can operate at lower voltages (below 50 volts), support lower power signal heads, integrate more comprehensive monitoring, and eliminate the need for forced ventilation. The net effect should be lower costs of operation, a much smaller cabinet, and lower power consumption for the entire intersection. Further, it could reduce the overall cost of maintenance by allowing signal technicians, rather than electricians to perform most conventional high-tech maintenance since there will be no line voltage in the cabinet or field wiring. This could produce a compact, safer, and greener cabinet. The project will proceed through with the procurement of 5 sample cabinets from each of 2 suppliers to verify both the procurement specification and the interchangeability of the major subassemblies. The cabinets will consider the communications now in use (NYCWiN) and the future (fiber) and support such additional features as digital CCTV, network devices, and video analytics. Further, this cabinet is expected to support the deployment of the connected vehicle technology as described by the AASHTO Footprint analysis and guidelines to prepare for the next generation connected vehicle development.
