Description |
|---|---|---|---|---|---|
| Roadside Message Sign Index: 2 | RS010 | 20 | 33 - 50 (1995) | 2 - 2 (1995) | Fixed message board for HOV and HOT lanes. |
| Wireline to Roadside Message Sign Index: 1 | RS013 | 20 | 6 - 8 (1995) |  | Wireline to DMS (0.5 mile upstation). |
| Dynamic Message Sign Index: 2 | RS015 | 10 | 41 - 101 (2005) | 2.0 - 5 (2005) | Low capital cost is for smaller DMS installed along arterial. High capital cost is for full matrix, LED, 3-line, walk-in DMS installed on freeway. Cost does not include installation. |
| Dynamic Message Sign Tower Index: 9 | RS016 | 20 | 28 - 136 (2005) | | Low capital cost is for a small structure for arterials. High capital cost is for a larger structure spanning three to four lanes. DMS tower structure requires minimal maintenance. |
| Dynamic Message Sign - Portable Index: 2 | | 14 | 15.9 - 21 (2005) | 0.5 - 1.6 (2005) | Trailer mounted DMS (three-line, 8-inch character display); includes trailer, solar or diesel powered, and equipped with cellular modem for remote communication and control. Operating costs are for labor and replacement parts. |
| Highway Advisory Radio Index: 1 | RS017 | 20 | 15 - 36 (2005) | 0.6 - 1 (2005) | Capital cost is for a 10-watt HAR. Includes processor, antenna, transmitters, battery back-up, cabinet, rack mounting, lighting, mounts, connectors, cable, and license fee. Super HAR costs can exceed $9K additional. Primary use of the super HAR is to gain a stronger signal. |
| Highway Advisory Radio Sign Index: 2 | | 10 | 4 - 8 (2005) | 0.22 (2005) | Cost is for a HAR sign with flashing beacons. Includes cost of the controller. |
| Roadside Probe Beacon Index: 2 | RS020 | 5 | 4 - 6 (2001) | 0.4 - 0.6 (2001) | Two-way device (per location). |
| LED Count-down Signal Index: 2 | | 10 | 0.261 - 0.361 (2001) | | Costs range from low (two 12x12-inch dual housing unit) to high (16x18-inch single housed unit). Signal indicates time remaining for pedestrian to cross, and a walk or don't walk icon. Count-down signals use low 8-watt LED bulbs, which require replacement approximately every five to seven years. |
| Pedestrian Crossing Illumination System Index: 2 | | 5 | 22.8 - 35 (2003) | 2.2 - 3 (2001) | The capital cost range includes cost of equipment and installation. Equipment includes fixtures, four lamps per lane for a three lane crosswalk, controller, pole, and push button activator. Installation is estimated at 150% to 200% of the total equipment cost. Capital cost would be greater if the system included automated activation of the in-pavement lighting system. O&M is approximately 10% of the equipment cost. |
| Variable Speed Display Sign Index: 2 | | | 3.0 - 4.0 (2001) | | Low range is for a variable speed limit display system. High range includes static speed sign, speed detector (radar), and display system. |
