Cycle path signs may be used as outlined in MOTSAM Part 1, Section 2-29 a and b(external link).
Road controlling authorities may mark cycle symbols at intervals along the cycle path. This is not a requirement but, as exclusive cycle paths are rare, it can be useful to do so to emphasise to people who are not cycling (motorcyclists, pedestrians or horse riders etc) that they are not entitled to use this path.
The cycle symbol can be as per the cycle lane symbol (see MOTSAM, Part 3, 2.11.4 [PDF, 2.3 MB] ) with a scale factor of X = 20 mm; this results in a cycle logo 360 mm wide and 560 mm high.
Bollard or other end of path treatments
When using bollards or other end of path treatments on cycle-only paths, for example to restrict access by other vehicles, the placement of the bollard is very important in terms of path user safety. The bollards need to be conspicuous and may require supporting pavement marking.
Design guidance can be found in the Austroads Guide to Road Design Part 6A – Pedestrian and Cyclist Paths(external link).
