I-Ped placements (A–D) to assess the effect of HH on detection of potential hazards for a right (R) or left (L) turn. Objects in the direction of A and D could be a hazard for a right-turning vehicle. Objects at or near A, C, and B could be a hazard for a left-turning vehicle. Thick lines: the outline of the recommended clear sight triangle for a stop-controlled intersection at a 30-mph cross street.19 The driver would have to scan almost 90° to the left and right to view the whole area within the sight triangle. Schematic is approximately to scale.
