Description |
|---|---|---|---|---|---|
| Linked Signal System LAN Index: 2 | RS002 | 20 | 20 - 47 (2005) | 0.3 - 0.5 (1995) | This element provides the connections to the linked signal system. |
| Signal Controller Upgrade for Signal Control Index: 2 | RS003 | 20 | 2.1 - 5 (2003) | 0.2 - 0.3 (2005) | Local controller upgrade to provide advanced signal control. |
| Signal Controller and Cabinet Index: 2 |  | | 7 - 12 (2005) | 0.2 - 0.4 (2005) | Includes installation of traffic signal controller per intersection. |
| Traffic Signal Index: 2 | | | 76 - 92 (2001) | 1.8 - 2.3 (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 Index: 2 | RS004 | 5 | 2 - 5 (2004) | 0.03 - 0.2 (2004) | Two per intersection. Complement of IDAS elements RS005 and TV004. |
| Signal Controller Upgrade for Signal Preemption Index: 2 | RS005 | 10 | 2 - 3 (2005) | | Add-on to base capability (per intersection). Complement of IDAS elements RS004 and TV004. |
| Roadside Signal Preemption/Priority Index: 2 | | 10 | 4 - 5 (2005) | 0.2 - 1 (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 exceed $20K to $30K per intersection if traffic control equipment and/or systems need to be replaced. |
| Ramp Meter Index: 2 | RS006 | 5 | 21 - 42 (2003) | 1.0 - 2.3 (2003) | Includes ramp meter assembly, signal displays, controller, cabinet, detection, and optimization. |
| Software for Lane Control Index: 3 | RS011 | 20 | 25 - 50 (1995) | 2 - 5 (1995) | Software and hardware at site. Software is off-the-shelf technology and unit price does not reflect product development. |
| Lane Control Gates Index: 2 | RS012 | 20 | 66 - 100 (1995) | 1.3 - 2 (1995) | Per location. |
| Fixed Lane Signal Index: 2 | RS009 | 20 | 4 - 5 (1995) | 0.4 - 0.5 (1995) | Cost per signal. |
| Automatic Anti-icing System - Short Span Index: 2 | | 12 | 19 (1998) | 1.5 (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. |
| Automatic Anti-icing System - Long Span Index: 2 | | 12 | 38 - 380 (1999) | 1.2 - 22.7 (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. |
