RDLENCINTE - Total road length of interstates Interstate length was calculated by summing the length of all interstates
in the 1 km grid cell reporting unit. Values are reported in meters.
Roads increase imperviousness, potentially decreasing water quality.
Roads also fragment habitat and may act as barriers, especially
to large mammals. Wider roads and higher traffic volumes will generally
have more adverse affects, and impact a larger surrounding area
then smaller, less traveled roads. |
