Queueing delay models for two-lane highway work zones

The paper describes the adaptation and application of queueing models to estimate average delay at two-lane highways operating with a lane closure. In their original form, the queueing models predicted impacts at highway intersections controlled by vehicle-actuated traffic signals. Validation efforts using simulation indicate that the adapted delay models adequately predict traffic performance at two-lane highway lane closures. (C) 1999 Elsevier Science Ltd. All rights reserved.
