How Road Design Improves Pedestrian Visibility

Safer crossings depend on drivers and pedestrians being able to see one another early enough to react. Street design can improve those sight lines by changing where people wait, where vehicles park, and how crossings are positioned.

Which design features help?

Curb extensions bring pedestrians closer to the edge of moving traffic and can prevent parked vehicles from blocking the view. Raised crosswalks make the crossing more prominent. Refuge islands place waiting pedestrians in a protected, visible location between traffic streams.

Why does visibility matter even at marked crossings?

Paint alone cannot compensate for a pedestrian hidden behind parked cars, a wide turning radius, or a crossing located where sight distance is poor. The physical geometry around the crossing affects how much time both road users have to recognize the conflict.

What should be reviewed?

Parking near the crossing, turning movements, road curvature, lighting, traffic speed, vegetation, lane width, and the location where pedestrians naturally want to cross.

Policy context

Sam supports improved intersections and crossings. Visibility is one of the practical criteria that can guide which safety improvements make sense at a specific location.
