Trade-off Between Cyclist Safety and Widths of Bicycle and Adjacent Parking Lanes

Rhode Island prestigiously ranked 14th of all states in the percent of transportation spending on bicycles, 1.3%, between 1986 and 1995. Within this period, it also suffered the lowest cyclist fatality rate, 1.1 fatality per million of population. Previous statistics are only diminished by the limited bicycle ridership experienced by the state. Bicycle lanes are increasingly credited with transforming potential cyclists into actual ones, thereby boosting bicycle ridership. At present, the on-roadway bicycle facilities afforded Rhode Islanders mainly consist of shoulder lanes. A targeted program of bicycle lane development can help enhance bicycle ridership in the state. Yet, an understanding of the safety aspects of bicycle lanes is necessary to prevent any detrimental impact to the cyclist safety ranking of the state. The overall safety of bicycle lanes is well documented. Also well documented is the safety of varied bicycle lane designs at intersections. Much less is known of the individual safety impacts of their design features at the mid-link. "Trade-off between Cyclist Safety, Bicycle Lane Selection, and Widths of Bicycle and Adjacent Parking Lanes" aims to positively establish guidelines, if not warrants, for the selection of bicycle lanes over other bikeways based on maximizing highway user safety. The study further aims to establish and quantify the crash reduction potential of wider bicycle and adjacent parking lanes. The knowledge gained can help ensure the deployment of the safest bicycle facilities in Rhode Island consistent with budget.
