ABSTRACT
Public transportation routes are the ultimate output of public transportation agencies. However, routes cannot be understood in isolation from the network in which they operate. The network confi guration is often central to performance and investment analysis, even of a single route. This confi guration is the product not only of conscious choice by current managers but also of the inherited urban form: its road patterns, development densities, geographical features, previous infrastructure investment decisions, demographics, and public expectations. Thus, the existing network facilitates or hinders how well investment and performance goals can be met.
