Abstract

High automobile dependence in North America has placed significant social and economic burdens on our communities due to its associated high frequency and severity of road collisions. Alternatively, Europeans make greater use of sustainable transportation modes, and experience generally lower traffic fatalities per capita, with comparable socio-economic status. In this research, a comprehensive literature review reveals that increased sustainable transportation mode splits - bicycling, walking and public transit - can lead to reduced traffic fatalities among bicyclists, pedestrians, and auto drivers/passengers. Moreover, a business case is proposed suggesting significant direct and indirect economic benefits of community bicycling programs. Last, community-based, macro-level Collision Prediction Models (CPMs) are discussed as a reliable empirical tool to quantify the road safety benefits of sustainable transportation systems. Existing and new CPMs are proposed to predict the overall collision reductions resulted from increased bicycle use, taking into account new variables related to bike-auto traffic mix, terrain, and bicycle infrastructure extracted from recent advances in GIS databanks. It is hoped that the success of these new models will facilitate economic justification for the necessary bicycle infrastructure investment programs towards accelerated community road safety improvements.
