CONGESTION THRESHOLDS FOR LANE ADDITIONS ON TOLLWAYS

This article explores the meaning of congestion on highway-type rural and suburban facilities, such as tollways and freeways, and develops congestion thresholds, above which it will be necessary to add lanes to specific sections of these facilities. The study originated from the need for the development of a tender for a major tollway facility in Israel. It was necessary to clearly identify the conditions at which the flow could be termed "congested," in the sense of lower levels of service, dense flows, and tense driving conditions. Several congestion measures for the defined purpose were explored. In the end, density of flow and the resulting flow rate were found to be the most appropriate measures.
