The design of rural at-grade intersections is often referred to as an 'art' rather than a 'science.' The specific decision of whether to provide a left-turn lane is an example of the lack of an available rational objective approach to a major problem. This research has reviewed the various techniques and procedures in use, has measured traffic characteristics at typical Iowa intersections, and has developed a rational approach as a guideline for inclusion of a left-turn lane. The procedure is based on relating the benefits to the road user to the cost of providing the added turning lane. (Author)
