I am trying to calculate line length in polygons.
the polygon file is large ~50,000, the polyline file are roads.

with smaller file sizes I used arcgis 'intersect' and then did tabular analysis.

the file size created by doing intersection is going to be too big to handle with this approach.

any suggestions?
