| Abstract | This report presents operational and safety findings and countermeasure recommendations from a comparative analysis of bicycle lanes (BLs) versus wide curb lanes (WCLs). The primary analysis was based on videotapes of almost 4,600 bicyclists in Santa Barbara, California, Gainesville, Florida, and Austin, Texas. The videotapes were coded to evaluate operational characteristics and conflicts with motorists, other bicyclists, or pedestrians. Significant differences in operational behavior and conflicts were found between BLs and WCLs, but varied depending on the behavior being analyzed. Wrong-way riding and sidewalk riding were much more prevalent at WCL sites compared with BL sites. Significantly more motor vehicles passing bicycles on the left encroached into the adjacent traffic lane from WCL situations compared with BL situations. Proportionally more bicyclists obeyed stop signs at BL sites; however, when a stop sign was disobeyed, the proportion of bicyclists with both "somewhat unsafe" and "definitely unsafe" movements was higher at BL sites. The vast majority of observed bicycle-motor vehicle conflicts were minor, and there were no differences in the conflict severity by type of bicycle facility. Bicyclists in WCLs experienced more bike/pedestrian conflicts while bicyclists in BLs experienced more bike/bike conflicts. An initial model fitted to the intersection conflicts showed no differences in the conflict rate by type of bicycle facility, but showed higher conflict rates for left turn movements. The overall conclusion is that both BL and WCL facilities can and should be used to improve riding conditions for bicyclists. The identified differences in operations and conflicts appeared to be related to the specific destination patterns of bicyclists riding through the intersection areas studied and not to the characteristics of the bicycle facilities. |
