• Abstract:
  Shared lane markings help convey to motorists and bicyclists that they must share the roads on which they operate. The markings create improved conditions by clarifying where bicyclists are expected to ride and by notifying motorists to expect bicyclists on the road. Figure 1 illustrates a generic sharrow as it appears in the 2009 version of the Manual on Uniform Traffic Control Devices (MUTCD).(1) The present study was sponsored by the Federal Highway Administration (FHWA), and its purpose was to evaluate the impact of several uses of shared lane pavement markings, specifically the sharrow design, on operational and safety measures for bicyclists and motorists. Experiments were conducted in Cambridge, MA; Chapel Hill, NC; and Seattle, WA. This TechBrief provides a summary of the findings from the research, and the corresponding main technical report (FHWA-HRT-10-041) provides additional details.(2)
