Note: Equipment list adjusted to 2014 dollars. The date in parentheses under the capital cost value and O&M cost value represents the dollar year from which the cost value was adjusted. All costs are in $K.
|Unit Cost Element||IDAS#||Life (years)||Capital Cost $K, 2014 Dollars (Year)||O&M Cost $K/year, Dollars (Year)||Description|
|Highway Advisory Radio||RS017||20||16.00 - 37.00 (2005)||0.60 - 1.00 (2005)||
Capital cost is for a 10-watt HAR. Includes processor, antenna, transmitters, battery back-up, cabinet, rack mounting, lighting, mounts, connectors, cable, and license fee. Super HAR costs can exceed $9K additional. Primary use of the super HAR is to gain a stronger signal.
|Roadside Probe Beacon||RS020||5||4.00 - 6.00 (2001)||0.40 - 0.60 (2001)||
Two-way device (per location).
|LED Count-down Signal||10||0.24 - 0.33 (2001)||
Costs range from low (two 12x12-inch dual housing unit) to high (16x18-inch single housed unit). Signal indicates time remaining for pedestrian to cross, and a walk or don't walk icon. Count-down signals use low 8-watt LED bulbs, which require replacement approximately every five to seven years.
|Highway Advisory Radio Sign||10||4.00 - 7.00 (2005)||0.20 - (2005)||
Cost is for a HAR sign with flashing beacons. Includes cost of the controller.
|Dynamic Message Sign||RS015||10||37.00 - 92.00 (2005)||1.80 - 5.00 (2005)||
Low capital cost is for smaller DMS installed along arterial. High capital cost is for full matrix, LED, 3-line, walk-in DMS installed on freeway. Cost does not include installation.
|Dynamic Message Sign Tower||RS016||20||29.00 - 141.00 (2005)||
Low capital cost is for a small structure for arterials. High capital cost is for a larger structure spanning three to four lanes. DMS tower structure requires minimal maintenance.
|Wireline to Roadside Message Sign||RS013||20|
|Dynamic Message Sign - Portable||14||14.40 - 19.00 (2005)||0.50 - 1.40 (2005)||
Trailer mounted DMS (three-line, 8-inch character display); includes trailer, solar or diesel powered, and equipped with cellular modem for remote communication and control. Operating costs are for labor and replacement parts.
|Roadside Message Sign||RS010||20||30.00 - 45.00 (1995)||2.00 - 2.00 (1995)||
Fixed message board for HOV and HOT lanes.
|Variable Speed Display Sign||2.70 - 3.70 (2001)||
Low range is for a variable speed limit display system. High range includes static speed sign, speed detector (radar), and display system.
|Pedestrian Crossing Illumination System||5||20.80 - 32.00 (2003)||2.00 - 3.00 (2003)||
The capital cost range includes cost of equipment and installation. Equipment includes fixtures, four lamps per lane for a three lane crosswalk, controller, pole, and push button activator. Installation is estimated at 150% to 200% of the total equipment cost. Capital cost would be greater if the system included automated activation of the in-pavement lighting system. O&M is approximately 10% of the equipment cost.
