Central Hatching - Wide Centrelines
Fewer head-on and overtaking crashes. Can remove turning vehicles from through traffic lanes, resulting in fewer rear-end and turning crashes and improved traffic flow. Improved delineation. Some reduction in speeds. Possible protection for pedestrians. Inexpensive.
If rumble strips, or other raised pavement devices are also used, the risk to motorcycles and pedestrians (trip hazard) must be considered. Coloured surfacing may be applied to the hatched area to further enhance the conspicuity of the treatment.
