Model 1 includes: on-road bicycle facility present, sidewalks, traffic controls, bicycle volume, motor vehicle volume, and curb-to-curb width. Likelihood ratio test: Model 1 vs. Univariate model (χ2=23.42, df=6, p<0.001)
Model 2 includes: on-road bicycle facility type, sidewalks, traffic controls, bicycle volume, motor vehicle volume, and curb-to-curb width. Likelihood ratio test: Model 2 vs. Univariate model (χ2=21.46, df=6, p=0.002)
Index street = street motor vehicle was traveling on when crash occurred
Non-index street = street motor vehicle was not traveling on when crash occurred
