ACTIVE ADVANCE WARNING SIGNS AT HIGH-SPEED SIGNALIZED INTERSECTIONS: A SURVEY OF PRACTICE (ABRIDGMENT)

A synthesis of current traffic engineering practice relative to accident countermeasures at high-speed signalized intersections is presented. The synthesis was prepared by using two main sources of information: a review of published and unpublished literature, and results of a questionnaire survey sent to practicing traffic engineers. Sixty-five state and local agency traffic engineers from all regions of the United States and Canada responded to the questionnaire. Physical environments known to cause problems at high-speed signalized intersections are described. The three most commonly used types of active advance warning devices are discussed along with quantitative and qualitative assessments of their effectiveness. The three types of devices are flashing RED SIGNAL AHEAD signs, PREPARE TO STOP WHEN FLASHING signs, and flashing strobe lights. Active devices are usually installed only as a last resort where conventional countermeasures have not proved to be effective. Although specific situations in which each type of device has been effective or in which its use should be avoided were identified, there is a need for guidelines to define the use, design, installation, and timing of active warning devices.
