oa Civil Engineering = Siviele Ingenieurswese - Lagging versus leading green right turn arrows

 

Abstract

At an intersection, the right turn is the movement with the highest accident potential and the lowest capacity. At the majority of intersections, right-turners must take gaps in opposing traffic. At a signalised intersection, drivers may be presented with a flashing green arrow to aid the right turn. The SADC Road Traffic Signs Manual (RTSM) describes the decision as whether or not to install a protected right-turn stage as the single most important factor when designing a signalised intersection.
