TRANSIT SYSTEM NETWORK DESIGN

This article formulates a transit network design model for determining frequencies of each transit line in a network. This transit network design model requires a mode-split assignment model with distinct transit lines, each with its own specified frequency, to capture the mode split effects of increases or decreases in individual transit line frequencies. It is shown how to refine conventional mode-split assignment models to include this feature. The resulting model includes more precise measures of transit access and transfer delays, so that it more accurately predicts mode choices and link flows. This variation of the mode-split assignment model uses Dial's transit loader to solve Frank-Wolfe subproblems, using frequencies of individual transit lines to find fastest transit paths, considering access time, ride time, and any transfer delays. Computational shortcuts using the standard Hooke-Jeeves algorithm are demonstrated.
