Abstract

"Urban safety has become a key issue for life in the city. A strategy that may positively affect quality of life is the urban design of public spaces; however, previous efforts have not been based on hard data, hampering a serious evaluation of alternative solutions. This work discusses the methodology and primary results of a study geared to quantify the perception of safety in low income areas, and how this is affected by the spatial arrangement of neighborhoods. We are interested in quantifying the effect of spatial variables regarding the feelings of fear associated with the use of public space, with the objective to evaluate policies to improve security based on hard data rather than unproven speculation. We designed and implemented a stated preference survey to measure the relative perceptions of insecurity experienced by residents traveling through specific neighborhoods in Santiago. The relative importance of each variable was determined using flexible discrete choice models. Results suggest that the proposed approach could become an efficient technique for the evaluation of urban safety policies"
