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.

Two-way device (per location).

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.

Cost is for a HAR sign with flashing beacons. Includes cost of the controller.

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.

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.

Wireline to DMS (0.5 mile upstation).

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.

Fixed message board for HOV and HOT lanes.

Low range is for a variable speed limit display system. High range includes static speed sign, speed detector (radar), and display system.

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.
