Two-way device (per location).

LED Count-down Signal 10 0.22 - 1.08 (2020)

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.

Highway Advisory Radio Sign 10 3.72 - 6.69 (2005) 0.19 - (2005)

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 - 251.45 (2020)

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 1.98 - 17.85 (2019) 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.
