Overview of Shared Use Lane Pavement Markings for Cyclists

The provision of cyclist markings on roadways is increasingly important as a means of encouraging cycling, which can help achieve greenhouse gas emission reduction goals, improve personal health, and alleviate traffic congestion. While reserved bicycle lanes are a common measure, there are situations where roadway geometry and/or operations do not readily lend themselves to bicycle lane implementation. As an alternative marking option, the shared-use pavement marking symbol, or "sharrow" may be used, and was recently adopted by TAC for use in Canada. The sharrow marking consists of two chevron markings placed in front of a bicycle stencil. The general purpose of the sharrow symbol is to indicate to cyclists the correct positioning on the roadway, and to indicate to drivers the position where cyclists may be expected. There are three general applications of this marking: 1) side-by-side cyclist-motorist operation, 2) single file cyclist-motorist operation, and 3) conflict zones. An overview of the marking design will be given, as well as an overview of the three applications in terms of marking placement, spacing, signage considerations and the range of applicability. Finally, a review of several case studies of actual device implementation will be presented, highlighting emergent issues with the use of this device.
