Available in PDF, EPUB and Kindle. Book excerpt: The primary contribution of this dissertation is the development of analytical relationships to determine the upstream and downstream boundary points that define the transition between basis tow-lane highway segments and the effective influence area of the signalized intersection and the TWSC intersection, as well as the corresponding method for calculation of an overall facility service measure based upon percent time-delayed and then translating it to a Level Of Service (LOS) grade. The dissertation focuses the efforts on developing the methodology for operational analysis of a two-lane highway with an isolated signalized intersection at the facility level. Nonetheless, this research also provides a model for the basic structure of a facility-level analysis that will be amenable to the incorporation of a variety of segment types. Finally the methodology has been incorporated into the existing HIGHPLAN software program.
