• Description:
  The London Roundabout on KY 363 at KY 1006 was programmed as a safety‐hazard elimination project. The city of London is located in Laurel County in south Kentucky (see Figure 1). The intersection at KY 363 and KY 1006 has been a high crash location for many years. The alignment of the KY 1006 southeast leg was badly skewed, which obstructed the drivers' line of sight when approaching the intersection. In the mid‐90s, KYTC converted the intersection to a four‐way stop. Prior to this, the intersection was two‐way stop controlled, with the stop condition on KY 1006. When this intersection was a two‐way stop, the crashes were frequent and often severe. When KYTC installed the additional stop signs, the crashes and their severity were reduced, and the capacity of the intersection was greatly diminished. While KYTC waited for the safety‐hazard elimination project to be delivered, they chose to live with low intersection capacity in order to reduce severe crashes. This intersection continued to have a high crash rate. In the three years prior to construction, 14 crashes were recorded, with one injury crash. Figure 2 shows an aerial view before roundabout construction was underway.
