Component

Left turn vehicles colliding with oncoming traffic is a common and significant type of intersection crashes. Drivers’ decision to select a proper gap to initiate a turn in the midst of opposing traffic is often affected by driver’s own preferences and traffic conditions. Sometimes driving behaviors are further complicated by particular circumstances, such as traffic signal transition and pedestrian presence in an urban environment. This paper describes a study of contributing factors in potential conflicts at signalized intersections where the turning vehicle and the other vehicles came close to each other in their trajectories. Data from field observations were analyzed in detail to categorize the primary factor and associated traffic attributes in the occurrence of conflicts. The understanding of such circumstances provides much insight into the issues to be resolved in constructing effective intersection collision warning systems.
