Lane change experiment that was aimed at reducing a traffic congestion

On an expressway which has two lanes running each way, there is a tendency for traffic to concentrate disproportionately in the inner lane when traffic volume reaches a high level just before actual congestion. When volume increases past this point, traffic in the inner lane begins to exceed that lane’s capacity, resulting in congestion occurring in the inner lane which immediately spreads to all lanes. At this point, the outer lane has not yet reached its capacity. In other words, traffic congestion is occurring even though the capacity of the two lanes is not being fully utilized. In order to sufficiently utilize the capacity of both lanes, it is desirable to correct the concentration of traffic volume in the inner lane during periods of high traffic volume by equalizing volume between to two lanes. This experiment was aimed at equalizing lane usage. The chief characteristic of this experiment was to change lane operation in the section from two traffic lanes, with a climbing lane added to the left and then closed on the left; to adding one lane on the right to make three traffic lanes, and then closing the left lane at the end of the section.
