Titel:
Examination of catchment areas for public transport

Abstract:
The paper presents a method to examine the catchment areas for stops in high quality public transport systems based on the street network in the examined area. This is achieved by implementing the Service Area functions from the ArcGIS extension Network Analyst. The method is compared to a more simple method using only the Euclidean distance from the examined stop and the paper describes the differences in detail-level of the results. Furthermore, the paper describes how the Service Area method can be used to examine increments in the catchment areas by adding extra entrances to stations or by making changes in the street network around the station. The paper also discusses the degree of realism in the used GIS networks and how it can affect the size of the catchment areas. It is concluded that the Service Area method improves the detail-level and accuracy in catchment area analyses. These improvements are well suited for examinations of changes in station entrances and/or street network.
