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|
|Linked Signal System LAN||RS002||20||18.00 43.00 (2005)||0.20 0.50 (1995)||
This element provides the connections to the linked signal system.
|Software for Lane Control||RS011||20||26.00 51.00 (1995)||3.00 5.00 (1995)||
Software and hardware at site. Software is off-the-shelf technology and unit price does not reflect product development.
|Signal Controller Upgrade for Signal Preemption||RS005||10||2.00 3.00 (2005)||
Add-on to base capability (per intersection). Complement of IDAS elements RS004 and TV004.
|Automatic Anti-icing System - Long Span||12||35.00 346.00 (1999)||1.00 20.60 (1999)||
Typical automatic anti-icing system consists of a control system, chemical storage tank, distribution lines, pump, and nozzles. Pump and control hardware replaced every 5 years. For a long span system ranging from 320 feet to greater than 1/2 mile. O&M includes system maintenance, utilities, materials, and labor. The high O&M cost is for a much larger system; hence, the need for a greater amount of materials.
|Fixed Lane Signal||RS009||20||4.00 5.00 (1995)||0.40 0.50 (1995)||
Cost per signal.
|Lane Control Gates||RS012||20||60.00 91.00 (1995)||1.20 2.00 (1995)||
|Roadside Signal Preemption/Priority||10||4.00 5.00 (2005)||0.20 1.00 (2005)||
Includes infrared detector, detector cable, phase selector, system software, and installation. Capital costs range is for two-directions. O&M cost estimate for operating, monitoring, and maintaining. Complement to transit (or emergency vehicle) on-board Signal Preemption/Priority Emitter. Capital costs can rise to $20K to $30K per intersection if traffic control equipment and/or systems need to be replaced.
|Ramp Meter||RS006||5||19.00 38.00 (2003)||0.90 2.10 (2003)||
Includes ramp meter assembly, signal displays, controller, cabinet, detection, and optimization.
|Signal Controller and Cabinet||6.00 11.00 (2005)||0.20 0.40 (2005)||
Includes installation of traffic signal controller per intersection.
|Signal Preemption Receiver||RS004||5||2.00 5.00 (2004)||0.03 0.20 (2004)||
Two per intersection. Complement of IDAS elements RS005 and TV004.
|Signal Controller Upgrade for Signal Control||RS003||20||1.90 5.00 (2003)||0.20 0.30 (2003)||
Local controller upgrade to provide advanced signal control.
|Automatic Anti-icing System - Short Span||12||17.00 (1998)||1.40 (1998)||
Typical automatic anti-icing system consists of a control system, chemical storage tank, distribution lines, pump, and nozzles. Pump and control hardware replaced every five years. For a short span system ranging from 120 to 180 feet. O&M includes system maintenance, utilities, materials, and labor.
|Traffic Signal||69.00 84.00 (2001)||1.70 2.10 (1999)||
Includes installation for one signal (four-leg intersection), conduit, controller, and detection device. Cost ranges from traffic signal with inductive loop detection (low) to non-intrusive detection (high).
