Roadside Control (RS-C)
Note: The date in parentheses under the capital cost value and O&M cost value represents the dollar year of the cost values. All costs are in $K.
| Unit Cost Element | IDAS# | Life (years) | Capital Cost $K (Year) | O&M Cost $K/year (Year) | Description | |
|---|---|---|---|---|---|---|
| Linked Signal System LAN | RS002 | 20 | 23.00 - 54.00 (2005) | 0.40 - 0.80 (1995) | This element provides the connections to the linked signal system. |
|
| Software for Lane Control | RS011 | 20 | 25.00 - 50.00 (1995) | 2.50 - 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 - 4.00 (2005) | Add-on to base capability (per intersection). Complement of IDAS elements RS004 and TV004. |
||
| Automatic Anti-icing System - Long Span | 12 | 50.00 - 495.00 (1999) | 1.50 - 29.50 (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. |
||
| Fixed Lane Signal | RS009 | 20 | 6.00 - 8.00 (1995) | 0.60 - 0.80 (1995) | Cost per signal. |
|
| Lane Control Gates | RS012 | 20 | 100.00 - 150.00 (1995) | 2.00 - 3.00 (1995) | Per location. |
|
| Roadside Signal Preemption/Priority | 10 | 5.00 - 6.00 (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 | 25.00 - 50.00 (2003) | 1.20 - 2.80 (2003) | Includes ramp meter assembly, signal displays, controller, cabinet, detection, and optimization. |
|
| Signal Controller and Cabinet | 8.00 - 25.00 (2020) | 0.20 - 0.50 (2005) | Includes installation of traffic signal controller per intersection. |
|||
| Signal Preemption Receiver | RS004 | 5 | 2.00 - 6.00 (2004) | 0.04 - 0.20 (2004) | Two per intersection. Complement of IDAS elements RS005 and TV004. |
|
| Signal Controller Upgrade for Signal Control | RS003 | 20 | 2.50 - 6.00 (2003) | 0.20 - 0.40 (2003) | Local controller upgrade to provide advanced signal control. |
|
| Automatic Anti-icing System - Short Span | 12 | 25.00 (1998) | 2.00 (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. |
||
| Traffic Signal | 95.00 - 115.00 (2001) | 2.40 - 3.00 (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). |
