Retrofit Access Management for Priority Corridors Overlaying GIS Crash & AADT Data on Aerial Photography

Use GIS technology to overlay crash and AADT data on aerial photography to identify retrofit access management priorities. Focus on moderate traffic volume, four-lane undivided cross-sections, few dedicated turn lanes, strip commercial land use, poor internal circulation design, high commercial driveway density, and short spacings between driveways, intersections, and signals.

  1. GIS Crash and AADT Data Overlayed on Aerial Photography To Identify Priority Corridors For Retrofit Access Management • Moderate traffic volume (AADT) • Four lane undivided cross section • Few dedicated turn lanes • Older “strip commercial” land use • Poor design of internal circulation and parking lots • High commercial driveway density • Short spacing between driveways • Short spacing between public road intersections • Short spacing between traffic signals
