Note: Equipment list adjusted to 2020 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, 2020 Dollars (Year)||O&M Cost $K/year, Dollars (Year)||Description|
|Highway Advisory Radio||RS017||20||17.53 - 40.91 (2005)||0.70 - 1.17 (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||3.45 - 5.51 (2001)||0.34 - 0.55 (2001)||
Two-way device (per location).
|LED Count-down Signal||10||0.22 - 0.31 (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||3.72 - 6.69 (2005)||0.19 - (2005)||
Cost is for a HAR sign with flashing beacons. Includes cost of the controller.
|Dynamic Message Sign||RS015||10||34.95 - 87.01 (2005)||1.71 - 4.46 (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||31.58 - 151.59 (2011)||
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||6.41 - 9.62 (1995)|
|Dynamic Message Sign - Portable||14||13.61 - 17.85 (2005)||0.45 - 1.34 (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||28.48 - 42.72 (1995)||1.42 - 2.14 (1995)||
Fixed message board for HOV and HOT lanes.
|Variable Speed Display Sign||2.55 - 3.45 (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||19.60 - 29.93 (2003)||1.89 - 2.89 (2001)||
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.
