1201. 1 1201. 2(b) INTELLIGENT TRANSPORTATION SYSTEM ( ITS) DEVICES

1201.1DESCRIPTION —This work is the furnishing and installing fully functional and operational Intelligent

Transportation System ( ITS) devices . Provide furnished items to be new and utilize the most current technology. Provide subsystems that minimize the possibility that failure of any one component or module causes total subsystem failure. Failure of one compone nt or module must not damage any other component or module. Provide device subsystems that proceed automatically to full -functional mode at the device location and at the TMC/RTMC or remote control location, without the need for human intervention, if related electrical power supply is turne d on or restored. Comply with the following standards and codes as indicated and where applicable: NEMA, NTCIP, ASTM, IEC, UL, EIA, NEC, and AASHTO. Furnish ITS devices conforming to and compatible with structures contained in Publication 852 and the Standard Drawings .

1201.2MATERIAL —

(a)Materials Acceptance. Section 106 and as follows.

For all ITS devices submit for approval, at no additional cost to the Department, catalog cuts, drawings, sources of supply , and additional submissions as follows before purchasing equipment.

1.ITS Enclosure. For enclosure heating and cooling subsystems, submit heat -load calculation sheets,

accompanied by related manufacturer’s data sheets, as support materials for justifying the heating/cooling sizing choices. Use worst -case heat -load data of the energized devices for the calculations. Submit power usage calculations to support power distribution type and size.

2.Uninterrupted Power Supply (UPS ). Submit calculation sheets, accompanied by manufacturer’s

data sheet listing the power requirement of critical components, as support materials for justifying the UPS sizing choices. Use worst -case power -load data for the calculations.

(b)ITS Enclosure. Utilize enclosure for ground- mounted, pole- mounted, or other structurally mounted

enclosure installations as shown on the Standard Drawings and as indicated. House all ITS device electronics in the ITS enclosures according to Publication 647 and as indicated in the contract documents. For pole- mounted and ground -mounted enclosures, provide all material, including mounting equipment, and a concrete pad or elevated pedestal, to meet the requirements contained in Publication 647.

1.NEMA 3R Enclosure. House device electronics in a locking, weather resistant NEMA 3R, UL50 E

listed aluminum enclosure. Furnish enclosure to provide protection from rain, sleet, snow, dripping water and corrosion. Construct complete enclosure from 0 .125- inch-thick aluminum alloy type 5052- H32 to provide strong and rigid construction. Provide enclosure with mini
