Description
Maximizing the potential capacity of existing roadways is becoming a
priority due to growing congestion and limited resources for adding more capacity to the highway
system. Including turn lanes in the design of a highway improvement project, or requiring turn
lanes to be added as a result of new development, is a complex decision requiring the Cabinet to
evaluate the anticipated demands for right or left turns to abutting land development and the
anticipated benefits in delay and crash reduction against the cost and other impacts of the
installation. The common method of analyzing and designing intersections on the basis of past
experience, accident records, complaints from the traveling public, and engineering judgment has
led to inconsistencies. Even where technical analysis is attempted, the most commonly used
analysis tool (the 1967 Harmelink Methodology) is of questionable value due to the facts that the
underlying assumptions are no longer valid for today's driving conditions and queue storage
lengths frequently need to be longer than those indicated by the limits ofthe Harmelink curves.
