Directional Average Weekday (24 hour average), AM Peak Hour (7-8 a.m.), PM Peak Hour (peak hour between 4-6 p.m.), and PM Peak Turn Movement (right, left, and through), are included in the summary. The final tab provides scanned PDF documents (where available) of the original count data for this intersection.
