Unit Cost Element IDAS# Life (years) Capital Cost $K, 2020 Dollars (Year) O&M Cost $K/year, Dollars (Year) Description
Linked Signal System LAN RS002 20 17.10 - 40.16 (2005) 0.23 - 0.46 (1995)

This element provides the connections to the linked signal system.

Software for Lane Control RS011 20 27.35 - 54.70 (1995) 2.73 - 5.47 (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 1.49 - 2.97 (2005)

Add-on to base capability (per intersection). Complement of IDAS elements RS004 and TV004.

Automatic Anti-icing System - Long Span 12 32.94 - 326.14 (1999) 0.99 - 19.44 (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 3.42 - 4.56 (1995) 0.34 - 0.46 (1995)

Cost per signal.

Lane Control Gates RS012 20 56.95 - 85.43 (1995) 1.14 - 1.71 (1995)

Per location.

Roadside Signal Preemption/Priority 10 3.72 - 4.46 (2005) 0.15 - 0.37 (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 17.81 - 35.63 (2003) 0.86 - 2.00 (2003)

Includes ramp meter assembly, signal displays, controller, cabinet, detection, and optimization.

Signal Controller and Cabinet 5.95 - 24.54 (2020) 0.15 - 0.37 (2005)

Includes installation of traffic signal controller per intersection.

Signal Preemption Receiver RS004 5 1.46 - 4.37 (2004) 0.03 - 0.15 (2004)

Two per intersection. Complement of IDAS elements RS005 and TV004.

Signal Controller Upgrade for Signal Control RS003 20 1.78 - 4.28 (2003) 0.15 - 0.30 (2003)

Local controller upgrade to provide advanced signal control.

Automatic Anti-icing System - Short Span 12 16.18 (1998) 1.29 (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 65.46 - 79.24 (2001) 1.58 - 1.98 (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).
