A comprehensive review of all crash types along US 27 was performed. There were 948 rear end crashes which was the predominant type of crash. Rear end crashes are common on an interrupted flow facility at intersections. As congestion increases, the probability of rear end collisions increases. Dense crash locations are US 27 at SR 64, between Sebring Parkway and South of Lakeview Dr, US 27 at SR 66 and US 27 at E Interlake Blvd/County Rd 621 E.

The second highest crash type are left turn crashes (476), followed by sideswipe crashes (345). Left turn crashes are generally caused by a motorist failing to stop at a red light or stop sign or failing to yield ROW to oncoming traffic. Sideswipes occur in an interrupted flow facility due to aggressive or negligent driving and thereby failing to keep proper lane
