The joint Industry Council and Traffic Engineering Council LightEmitting Diode (LED) Specification Committee has completed a working group draft of the following new LED purchase specifications:

Vehicle Traffic Control Signal Heads Part 3: Light-Emitting Diode (LED) Vehicle Arrow Traffic Signal Modules

The purpose of this specification is to provide minimum performance requirements for 300-millimeter (mm) or 12inch (in.) LED arrow traffic signal modules. This specification is not intended to impose restrictions upon specific designs and materials that conform to the purpose and the intent of the specification. This specification refers to definitions and practices described in "Vehicle Traffic Control Signal Heads," published in Equipment and Material Standards of the Institute of Transportation Engineers. This specification applies to modules purchased after the effective date of the specification and is not restricted to any specific LED technology.

Pedestrian Traffic Control Signal Indications Part 2: Light-Emitting Diode (LED) Pedestrian Traffic Signal Modules

The purpose of this specification is to provide minimum performance requirements for LED "walking person" and "hand" icon pedestrian signal modules. This specification includes the following three sizes (nominal message bearing surface): 406 mm x 457 mm (16 in. x 18 in.), 305 mm x 305 mm (12 in. x 12 in.) and 229 mm x 229 mm (9 in. x 9 in.). This specification is not intended to impose restrictions upon specific designs and materials that conform to the purpose and intent of the specification. This specification refers to definitions and practices described in "Pedestrian Traffic Control Signal Indications," published in Equipment and Material Standards of the Institute of Transportation Engineers. This specification applies to modules purchased after the effective date of the specification and is not restricted to any specific LED technology.

These standards can be found on ITE on the Web at www.ite.org/standards/ led.asp.
