Black spots

Black spots are road locations that have a record of large numbers of crashes. There are often common problems at these sites which can be treated with engineering methods.

Examples of problem solving for intersection-related crashes:

• conversion of unsignalised cross intersections to roundabouts
• new or revised traffic signals
• grade separation
• staggered cross intersections
• extension of median through intersections (turn prohibited)
• provision of protected right turn facilities.

Examples of problem solving for non-intersection-related crashes:

• central median to divide the road
• pedestrian facilities
• shoulder sealing
• removal and/or shielding of roadside hazards
• road delineation
• overtaking lanes.
