abstract="Left-turning vehicles cause fewer problems at a signalized intersection when it operates under low volume condition. As the traffic volume of an intersection approaches capacity, however, fewer opportunities for left-turning maneuvers exist. The left-turning vehicles may suffer long delays before clearing the intersection. Thus, drivers sometimes become impatient and make hazardous maneuvers after experiencing long delays.<p />",
