A METHODOLOGY FOR THE ASSESSMENT OF TRUCK LANE NEEDS IN THE TEXAS HIGHWAY NETWORK. FINAL REPORT

Special truck lanes have been proposed as a measure for dealing with the increasing traffic of larger and heavier trucks on the Texas highway system. This report describes an integrated network modelling methodology for the study of truck lane needs in the Texas highway network. It consists of three major components: critical link programming, network traffic assignment, and optimal link selection/network design. The critical link programs allow the user to diagnose and assess the adequacy of the links in a highway network for handling excessive truck traffic under specified conditions. The traffic assignment model is essential for the prediction of link flow patterns and subsequent user costs calculation in response to particular changes in the network corresponding to truck-related link improvements. The assignment problem addressed here allows the asymmetric interaction between cars and trucks sharing the roadway in the determination of link travel times. The optimal link improvement selection problem is cast as a discrete network design problem with multiple improvement options per link. One of its main features is the definition of link improvement in terms of both lane addition (capacity expansion) and operating scheme (lane access restrictions to cars and trucks).
