The fact is, there is a precise width of lane that must exist for cyclists to operate their vehicles safely, and it's not the 4ft standard width bike lane, nor is it the 6ft standard width bike path, nor is it the 14ft wide outside lane.
Traffic Operations. Lane width has an effect on traffic operations and highway capacity, particularly for high-speed roadways. The interaction of lane width with other geometric elements, primarily shoulder width, also affects operations. When determining highway capacity, adjustments are made to reflect the effect of lane width on free-flow speeds. Lane widths of less than 12 feet (3.6 meters) reduce travel speeds on high-speed roadways, as summarized in Tables 4 and 5.
