About the Seminar
Estimating exposure to risk and assessing crash risk is necessary to understand and prevent crashes and injuries. However, transportation planners and engineers historically have lacked information about bicycle demand or traffic volumes needed to identify vulnerable locations for bicyclists and evaluate the effectiveness of safety improvement programs.
This presentation will describe how researchers used peak hour counts of bicycle traffic at locations throughout Minneapolis and facility demand models estimated from those counts to characterize exposure to risk on the street network in the city. The researchers aggregated bicycle crashes from 2005 to 2010 to estimate crash rates, estimated the probability of crashes at intersections and on street segments, and assessed the effects of built environment variables on the probability of bicycle crashes. Study findings, including that the probability of crashes is higher along street segments with higher land-use mix and commercial use and at intersections with higher job accessibility, will be shared. In addition, the implications for bicycling safety and facility improvements will be discussed.
