ACCIDENT ANALYSIS OF LEFT TURN PHASING
Information on the effect of protected/permitted phasing on accidents is limited. Data from previous studies are not definitive but consistently indicate that when protected-only phasing is changed to protected/permitted, the number of left turn accidents increases sharply, while all other accidents generally increase slightly or not at all. However, the number of left turn accidents tends to decrease over time, particularly after the first 6 months as motorists become acclimated to the protected/permitted phasing. The study described in this article was conducted to further examine the effect of protected/permitted left turn phasing on accidents. The investigation was limited to high-speed signalized intersections with separate left turn lanes on the treated approaches.
