Changeable lane Assignment However, traffic demands can have entirely different characteristics between AM, Mid-Day, and PM peak operations, leading to the need for different lane use controls on a time-of-day (TOD) basis. In addition to the recurring daily traffic patterns that may require differing lane use control, freeway incidents often impact frontage roads by creating high frontage road traffic demands as diversion from freeway mainlanes occurs. While lane use information at intersections is typically communicated via pavement markings and static signing, static traffic control devices cannot accommodate situations where turning movement demands vary significantly over short periods

Unformatted text preview: of time (e.g., cyclical variations or during incidents). This shortcoming of static traffic control can significantly impact the efficiency of traffic operations when permitted lane use does not adequately match traffic demands. The Changeable Lane Assignment System (CLAS) on frontage roads addresses the lane imbalances seen on both a TOD basis and when freeway incidents change typical frontage road traffic demands. As traffic signals have long been used as a "time management" technique for optimizing traffic operations, CLAS is used as a "space management" technique to add an additional dimension to optimizing traffic operations....
