6Summary of Literature Review and Design Guidelines This section provides a summary of available literature related to the design of bicycle lanes. It is divided into two parts: Section 2.1 summarizes safety and design research related to bicycle lanes and shared use lanes, and Section 2.2 summarizes guidance from the AASHTO Bike Guide related to the design of bicycle lanes and presents a summary table of recommended bicycle lane widths from other domestic and international guidance documents.

8one vehicle was turning right. In contrast, a 15-ft-wide curb lane was found to be optimum since it provided a safe degree of space between motor vehicles and cyclists while not providing enough space for motorists to attempt to use the additional space as a travel lane.

10 • Accessibility, • Personal safety/security, • Stops, • Conflicts, • Maintenance, • Pavement surface quality, • Truck and bus traffic, • Traffic volumes and speed, • Bridges, • Intersection conditions, • Costs/funding, and • State and local laws and ordinances. With respect to the design of bike lanes, the AASHTO Bike Guide indicates that bike lanes can be incorporated into a roadway when it is desirable or where there is a high potential for bicycle use to delineate available road space for preferential use by cyclists and motorists, which provides for more predictable movements by both.
