Example 100m buffer. I got intersected road polyline parts for the 100m buffer using a main road network shape file.

I got the output raster with 0.00000024. The unit for this output raster should be kilometer per square kilometer(km/sqkm2) as given in units, since my road length is 262 meters for the buffer.
