IN-PAVEMENT FLASHING CROSSWALKS - STATE OF THE ART

The past several years have seen the development and perfection of a new treatment for uncontrolled marked crosswalks. The device is known by many terms, including "Illuminated Crosswalk"; however, the most commonly known device of this type is generally referred to as an "in-pavement flasher system" (IPF). These devices are mounted in the street pavement to provide a flashing yellow light while the pedestrian crossing is in use. IPF systems address concerns that motorists may "tune out" conventional flashing beacons that are operated continuously. Motorists appear to be more apt to notice a device that is currently flashing, if it normally does not flash. Further, motorists may be more likely to properly react to the warning condition, if the flashing operation is more closely associated with the condition, not the site. The City of Fountain Valley, California retained Katz, Okitsu & Associates to review the state-of-the-art for use of IPFs. The study included a survey of existing users to obtain their experiences and opinions. Thirty-five public agencies were identified to use IPF systems when the study was being conducted in the year 2000. This represented about 100 installations, mostly in the states of California and Washington. However, the number of agencies that have installed these systems and the number of locations have continued to increase since the study was completed. This paper reviews current policy on usage of IPFs, system history and manufacturers, site characteristics, user satisfaction, detection issues, effectiveness and safety benefits, and comparison with alternative treatments. The paper concludes with recommendations for the use of IPF systems.
