Abstract
 Using GIS to Determine Risk Factors of Urban Bicyclists Track: Transportation Author(s): Elizabeth Cahill, Jean-Claude Thill, Eric Delmelle As issues related to oil dependencies, rising gas prices, and global warming come to the forefront of topics of concern for Americans, the need for alternative modes of transportation has become critical. Urban settings are seemingly ideal for bicycling to become a predominant mode given the compactness of destinations. However, in the United States, bicycling is both scarcely used and very dangerous as bicyclists are 12 times more likely to be killed than automobile drivers. The purpose of this study is to use GIS to model bicycle accidents in Buffalo, NY in order to determine and compare risk factors of both child and adult bicyclists. Physical road characteristics such as intersection composition(arc-node connectivity), and road classification in addition to social variables and potential trip attractors are examined. Given the spatial nature of these variables, a spatially weighted regression model is incorporated to limit potential dependencies amongst the attributes.
