Abstract:The NCDOT has made significant strides to reduce collisions and increase capacity along
strategic highway corridors across the state. Efforts have led to the implementation of many
different access management techniques along corridors, such as installing medians versus
two-way left turn lanes, using leftovers, closing median openings, and installing superstreets.
The Department has continued to receive comments from businesses along these corridors
indicating their concern that these new designs will have a negative economic impact because
of the lack of direct access to their properties. This study employs a perception based survey
technique with the use of comparison sites to create a pseudo before-after study. Owners of
businesses along treatment corridors viewed access management techniques in a more positive
light than the perceptions of those on comparison sites. Their similar performance in terms of
business revenues indicates that there is no direct evidence of negative economic impacts due
to access management installations.
