The vast majority of bicycle facilities are shared routes: low-speed streets safely shared by cars and bikes. A complete bicycle network utilizes three other types as well:
- Bicycle trails are entirely removed from high speed traffic.
- Bicycle lanes are typically on medium-speed roads, and are separated by lines on the road.
- Bicycle boulevards are designed to accommodate cyclists over motorists, using traffic-calming strategies.
All four have an important role in a bicycle network.
To make the major destinations in a city accessible by bike, the first step is to determine the extent of the existing bicycle network, and then grow the network using various facility types. To complete the network, parking facilities as well as adequate transit accommodations must also be available.
