Flashing beacons (also called flashers or flashing lights) are frequently requested in the belief that they will reduce vehicle speeds and make drivers more alert of the road conditions. Unfortunately, national studies indicate that this is frequently not the case. It has been found that flashers can yield an initial benefit, however they soon lose much of their effectiveness (typically after 3-months) and the flasher is ignored because it becomes part of the normal driving environment. Therefore Traffic Operations does not recommend installation of unjustified flashers. For any traffic control to be effective (including flashers) it must command the respect of the traveling public and provide a useful function. If you have a safety concern that you would reviewed, please contact Traffic Operations via a Work Request, or email us at firstname.lastname@example.org, or call 770-528-1600.
