Index: 2 | RS002 | 20 | 20.0 - 48.0
(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 - 5.0
(2003) | 0.2 - 0.4
(2005) | Local controller upgrade to provide advanced signal control. |
Signal Controller and Cabinet
Index: 2 |  | | 7.0 - 12.0
(2005) | 0.2 - 0.4
(2005) | Includes installation of traffic signal controller per intersection. |
Traffic Signal
Index: 2 | | | 78.0 - 94.0
(2001) | 1.9 - 2.4
(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 | 2.0 - 5.0
(2004) | 0.03 - 0.20
(2004) | Two per intersection. Complement of IDAS elements RS005 and TV004. |

Automatic Anti-icing System - Short Span
Index: 2 | | 12 | 19.0
(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 | 39.0 - 388.0
(1999) | 1.2 - 23.1
(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. |
