location of transit lines and stations, as well as scheduling, provides an essential guide to research problems for all scholars. Although the reader may not agree with each of his problem formulations, Vucbic's consistent and expert expression of problems at various geographic scales, and his review of the current status of their solution in research and practice, provides an essential startin...

An origin-based solution algorithm, named OBTAIN (origin-based traffic assignment for infrastructure networks), was recently developed for solving the traffic assignment problems (Bar-Gera and Boyce, 2003). This algorithm defines the solution variables in an intermediate way between links and routes, and has been proven to be superior to the link-based Frank-Wolfe method in both computational t...
