There are two major categories of bicycle facilities: 1) on-road facilities, and 2) separate facilities. Because the existing roadway network can be used by bicyclists to travel to almost any destination in and out of the region, the on-road facilities are the most important for bicycle transportation purposes. Separate facilities--such as bike paths and multi-purpose trails-- are designed and designated exclusively for bicycles and other non-motorized uses. Trails and greenways typically serve both recreation and transportation purposes and are important additions to the on-road facilities.
