Job accessibility tends to be one of the most important factors in transit planning. Major investments warrant careful study of all significant social, environmental, physical, and financial impacts. However, practice incorporates job accessibility analysis only speculatively and generally at best. This paper addresses how new GIS analytical and modeling methods for quantitatively measuring job accessibility may be incorporated into contemporary transportation planning practice. It provides an example of the technique's application and reviews its limitations and potential in the context of transportation planning practice.
