ACCIDENT COUNTERMEASURES AT HIGH-SPEED SIGNALIZED INTERSECTIONS. PHASE 1. SYNTHESIS OF PRACTICE
Physical environments known to cause problems at high-sped signalized intersections are described. The three most commonly used types of active advance warning devices are discussed along wiht quantitative and qualitative assessments of their effectiveness. The three types of devices are: (1) flashing RED SIGNAL AHEAD signs, (2) PREPARE TO STOP WHEN FLASHING signs and (3) flashing strobe lights. Active devices are usually installed only as a last resort where conventional countermeasures have proven not to be effective. While specific situations where each type of device has been effective or where 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. devices.
