Bicycle transportation planning and engineering

It includes the study and design of dedicated transport facilities for cyclists (e.g. cyclist-only paths) as well as mixed-mode environments (i.e. where cyclists share roads and paths with vehicular and foot traffic) and how both of these examples can be made to work safely.

However, the international numbered-node cycle network has a modular design that enables arbitrary routes using simple signage.

NACTO guidelines state "desired width for a cycle track should be 5 feet (1.5 m).

In areas with high bicyclist volumes or uphill sections, the desired width should be 7 feet (2.1 m)".

Advanced stop lines are one example of road markings on mixed mode shared space as cycling infrastructure.
