The term "transit desert" is a new concept that looks at the gap between level of transit service (supply) and needs of a particular population (demand). These populations are often referred to as "transit dependent," people that are too young, too old, or too poor or who are physically unable to drive. " Transit deserts" in this case are defined as areas that lack adequate public transit service given areas containing populations that are deemed transit-dependent. This study aims to analyze and establish a clear method for calculating and quantifying gaps between transit demand and supply using Geographic Information Systems (GIS). The study looks at four major U. S. cities: Charlotte, North Carolina; Chicago, Illinois; Cincinnati, Ohio; and Portland, Oregon. Transit deserts often occur in neighborhoods surrounding historic downtowns; however, exceptions occur in very isolated rural areas.
