“Looking for a state database of highway-railway intersection crashes. Railroad layer in GIS and overlay highway, with a point feature of all railroad crossings and do a buffer around the crossings to see what crashes come up (5 years).”
We delivered two shape files. One has the 2013-2017 crashes within 150 feet of an active rail crossing. The second shape file has the 2013-2017 crashes within 150 feet of a an abandoned rail crossing.
We chose a 150 ft. buffer instead of the 100 ft. initially requested because these buffers were based on a single point at the center of the intersection. We used the extra 50 ft. to account for the width of the pavement around the crossing, that way the 100 ft. buffer extended from the edges of the crossing instead of the very center of the crossing.
KTC has helped my team with two projects now. The crash data they provided has been essential to improving our safety estimation tools. The work KTC does is outstanding and important to making our highways safer and I look forward to working with them on future projects!
