Physical Description

29 pages; maps


GIS address-matching and overlay techniques can be used in the analysis of specialized transportation problems. These techniques enhance the spatial resolution of transportation services relative to the locations of potential users of the service. This allows planners to evaluate accessibility issues for identifiable user groups and thus make decisions about the feasibility of adjusting routes or schedules, or providing new services for these users. A case study focused on the commuter base of Oregon Health Sciences University is presented as an example of such an application.
