16. Abstract

This report is a comparative analysis of bicycle lanes (BLs) versus wide curb lanes (WCLs). The primary

analysis was based on videotapes of almost 4,600 bicyclists (2,700 riding in BLs and 1,900 in WCLs) in the cities ofSanta Barbara, CA, Gainesville, FL, and Austin, TX, as the bicyclists approached and rode through eight BL andeight WCL intersections with varying speed and traffic conditions. The intent was to videotape bicyclists whoregularly ride in traffic. The videotapes were coded to learn about operational characteristics (e.g., intersectionapproach position and subsequent maneuvers) and conflicts with motor vehicles, other bicycles, or pedestrians. Aconflict was defined as an interaction between a bicycle and motor vehicle, pedestrian, or other bicycle such that atleast one of the parties had to change speed or direction to avoid the other. Both bicyclist and motorist maneuvers inconflict situations were coded and analyzed. This covered maneuvers such as a bicyclist moving incorrectly from thebicycle lane into the traffic lane prior to making a left turn, or conversely, a motor vehicle passing a bicyclist and thenabruptly turning right across its path. Bicyclist experience data were also collected separately from the videotaping ateach of the 16 data collection sites in each city through use of a short oral survey. Slightly more than 2,900 surveyswere completed. These data were analyzed to learn about the age, riding habits, and experience levels of thebicyclists riding through these intersections. Bicycle-motor vehicle crash data were also analyzed to determine ifthere were parallels to the videotape data.

In addition to this final report, there is a separate report (FHWA-RD-99-035) containing a synopsis of the keyfindings of the final report and recommended countermeasures, as well as a guidebook (FHWA-RD-99-036) aboutinnovative bicycle accommodations.
