Effect of Yellow-Interval Timing on Red-Light-Violation Frequency at Urban Intersections
This study shows that an increase of 0.5 to 1.5 seconds in yellow-light duration will decrease the frequency of red-light running by at least 50 percent.
92% Reduction In Red Light Violations With Longer Yellow Light Times
Thanks to a simple traffic engineering fix -- increasing the yellow light duration -- the number of left-turn violations in Loma Linda, California dropped 80 to 85 percent from about 240 monthly violations to about 25 or 30 a month immediately after the change. Straight through violations were reduced 92 percent.
