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

Dynamic Message Sign RS015 10 34.95 - 87.01 (2005) 1.71 - 4.46 (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 31.58 - 151.59 (2011)

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 Roadside Message Sign RS013 20 6.41 - 9.62 (1995)
Dynamic Message Sign - Portable 14 13.61 - 17.85 (2005) 0.45 - 1.34 (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.

Pedestrian Crossing Illumination System 5 19.60 - 29.93 (2003) 1.89 - 2.89 (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.
