Statewide Safety Study of Bicycles and Pedestrians on Freeways, Expressways, Toll Bridges, and Tunnels--"Based on the literature and investigations done as part of this study, highway bicycle collision rates per mile of
bicycle travel are an order of magnitude higher than collision rates for motor vehicle traffic. Bicycle collisions
are no more frequent on bridges and in tunnels than on the approaches to the bridges and tunnels. Overall
vehicle collision rates are no higher on freeways open to bicycles than they are on adjacent highways open to
bicycles."
