2.0 TRAFFIC VOLUMES
Existing traffic counts were conducted during the second week of February 2012. The data
collection included typical weekday AM, Noon, and PM peak hour turning movement counts at
each of the study intersections. Turning movement counts were also conducted on a Saturday
afternoon peak period. In addition, 24-hour directional counts were collected on Ohio Drive
between SH 121 and Lebanon Road.

Currently, Ohio Drive carries approximately 12,600 vehicles per day (vpd) between SH 121 and

in which northbound and southbound traffic volumes are relative equal.
