Description |
| Linked Signal System LAN | RS002 | 20 | 23.0 - 54.0
(2005) | 0.4 - 0.8
(1995) | This element provides the connections to the linked signal system. |
| Signal Controller Upgrade for Signal Control | RS003 | 20 | 2.5 - 6.0
(2003) | 0.2 - 0.4
(2005) | Local controller upgrade to provide advanced signal control. |
| Signal Controller and Cabinet |  | | 8.0 - 14.0
(2005) | 0.2 - 0.5
(2005) | Includes installation of traffic signal controller per intersection. |
| Traffic Signal | | | 95.0 - 115.0
(2001) | 2.4 - 3.0
(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). |
| Signal Preemption Receiver | RS004 | 5 | 2.0 - 6.0
(2004) | 0.04 - 0.20
(2004) | Two per intersection. Complement of IDAS elements RS005 and TV004. |
| Signal Controller Upgrade for Signal Preemption | RS005 | 10 | 2.0 - 4.0
(2005) | | Add-on to base capability (per intersection). Complement of IDAS elements RS004 and TV004. |
| Roadside Signal Preemption/Priority | | 10 | 5.0 - 6.0
(2005) | 0.2 - 1.0
(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 | 25.0 - 50.0
(2003) | 1.2 - 2.8
(2003) | Includes ramp meter assembly, signal displays, controller, cabinet, detection, and optimization. |
| Software for Lane Control | RS011 | 20 | 25.0 - 50.0
(1995) | 2.5 - 5.0
(1995) | Software and hardware at site. Software is off-the-shelf technology and unit price does not reflect product development. |
| Lane Control Gates | RS012 | 20 | 100.0 - 150.0
(1995) | 2.0 - 3.0
(1995) | Per location. |
| Fixed Lane Signal | RS009 | 20 | 6.0 - 8.0
(1995) | 0.6 - 0.8
(1995) | Cost per signal. |
| Automatic Anti-icing System - Short Span | | 12 | 25.0
(1998) | 2.0
(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 at cost of $3.5K. For a short span system ranging from 120 to 180 feet. O&M includes system maintenance, utilities, materials, and labor. |
| Automatic Anti-icing System - Long Span | | 12 | 50.0 - 495.0
(1999) | 1.5 - 29.5
(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 five years at cost of $3.5K. 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. |
