Description
Since the implementation of KYTC's auxiliary turn lanes policy, Highway Districts have experienced
some locations that do not experience safety related impacts, but have significant queuing and delays
from left turning volumes that do not meet the left turn lane threshold. Other states, notably Indiana,
have used Passing Blister designs, which provide wider areas of full depth pavement to accommodate
passing on the shoulder under these conditions. The overall effectiveness of such design has not been
fully evaluated though the reduced cost and potential for an effective solution as demonstrated by
other states points to this as a potential solution for low volume left turn lane blockages.
The objective of this research is to evaluate the cost-effectiveness of passing blister design on reducing
delay and improving safety as compared to traditional left turn lane designs.
