Abstract:

This study investigated the safety effectiveness of the flashing yellow arrow (FYA) treatment at signalized intersections. One objective of this strategy was to reduce the frequency of left-turn (LT) crashes, especially those that involve a collision between left turns and vehicles traveling straight through from the opposite direction (also called leftturn opposite through (LTOT) crashes). Many studies have explored the safety effectiveness of FYAs. However, most of them only used data from one State, and the studies that used data from multiple States had limited samples of intersections. It is clear that an evaluation with a large sample of sites from multiple States would provide useful information to practitioners on the effectiveness of this treatment under different circumstances.
