Accessibility Calculations In Six Swedish Towns
Free (open access)
The Swedish National Road Administration (Vägverket) has financed the development of a GIS-method (Geographic Information System) to analyze different users’ accessibility to different facilities in real footway, cycleway, public transport and car networks. The focus is on the standard setting user groups (children, elderly and the disabled) in Swedish transport policy as well as on women and their assumed demands concerning safety, security and comfort in foot- and cycleway networks. The method has been used in six Swedish towns, Helsingborg (86872 inhabitants), Umeå (70844), Luleå (57560), Trelleborg (24722), Alingsås (22183) and Säffle (9222). The foot- and cycleway networks have been given 24 different attributes, which are considered to be of importance for the safety, security and convenience of the user groups studied. Different accessibility analyses have been performed within the project To calculate public transportation accessibility, a GIS-model has been built, which connects bus stops to the foot- and cycleway network. The GIS-model for car use considers one-way streets, forbidden turns and average speed. Like the other models it can calculate travel time between real estate coordinates of free choice. Using these three models it is possible to calculate accessibility and travel time quotients between the four modes of travel with origin and destination of free choice among the real estate coordinates. The latest report from the project, (Reneland) is written in Swedish. A paper on the background of the project was presented in English at the Urban Transport IX conference (Reneland). Keywords: GIS, accessibility, traffic safety, impaired individuals, children, walking, bicycling, public transport.
