Design criteria were developed for a bicycling network in which the design user is older children and other easy riders cyclists who want to be separated from traffic stress. Stress mechanisms such as overtaking traffic, parking turbulence, and right turning traffic were analyzed to determine criteria for traffic volume, speed, parking, lane width, and other traffic and roadway factors at which a bicycle route becomes unacceptably stressful, and for design features that reduce traffic stress. Facilities examined were shared lanes, bike lanes, bicycle contraflow both with and without centerline marking, and no-passing-bikes zones. The latter is a proposed facility for narrow streets with low speeds but traffic volumes too high to support lane sharing. When applying these criteria to design of a town-wide bicycle network, contraflow and no-passing-bikes zones were found to provide critical links for creating direct, low-stress bike routes.
