Highway Planning and Operations for the Dallas District: Freeway Operations UnderCongested Conditions

摘要

Freeway bottlenecks are a primary source of congestion, and the removal ofserveral bottlenecks in Dallas has shown a favorable reduction in delay. Solving a freeway bottleneck can be highly complex, and existing analytical tools have been inadequate for congested conditions. Driving behaviors in congestion were observed at several sites on freeways in Dallas and include queue jumping, weaving in congestion, and shoulder driving. These observations have furthered the understanding of freeway operations in congestion.
