|---|---|---|---|---|---|---|
| Roadside Message Sign | RS010 | 20 | 50.0 - 75.0 (1995) | 2.5 - 3.75 (1995) | Fixed message board for HOV and HOT lanes. |  |
| Wireline to Roadside Message Sign | RS013 | 20 | 6.0 - 9.0 (1995) |  | Wireline to DMS (0.5 mile upstation). | |
| Dynamic Message Sign | RS015 | 10 | 47.0 - 117.0 (2005) | 2.3 - 6.0 (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 | RS016 | 20 | 25.0 - 120.0 (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 | | 14 | 18.3 - 24.0 (2005) | 0.6 - 1.8 (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 | RS017 | 20 | 15.0 - 35.0 (2005) | 0.6 - 1.0 (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 an additional $9K to $10K (larger antenna). Primary use of the super HAR is to gain a stronger signal. | |
| Highway Advisory Radio Sign | | 10 | 5.0 - 9.0 (2005) | 0.25 (2005) | Cost is for a HAR sign with flashing beacons. Includes cost of the controller. | |
| Roadside Probe Beacon | RS020 | 5 | 5.0 - 8.0 (2001) | 0.5 - 0.8 (2001) | Two-way device (per location). | |
| LED Count-down Signal | | 10 | 0.325 - 0.450 (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 | | 5 | 27.5 - 42.0 (2003) | 2.75 - 4.20 (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 | | | 3.7 - 5.0 (2001) | | Low range is for a variable speed limit display system. High range includes static speed sign, speed detector (radar), and display system. | |
