LEFT-TURN PHASES--WHO NEEDS THEM?

A Los Angeles area ITE study shows how it is possible to evaluate, on the ground, how extensive the need for left-turn phasing is. Left-turn phasing should only be considered as a possible solution to a problem (either measured or projected) and only after less restrictive measures (for the majority of traffic involved) have been considered and rejected on the basis of factual engineering study. The two most common problems - excessive left-turn collisions and excessive left-turn delay - should be determined by real measurement whenever possible.
