The distinction between `streets' and `roads' has become a familiar convention in Australian traffic and network planning. However, the question arises of whether or not the concept underlying this distinction is valid in traffic policy, especially in relation to existing networks. This paper updates the concept in the context of the `traffic calming' typology. The scope of environmental traffic management has broadened beyond the local street system; so-called `Level II traffic calming' involves environmental traffic management on district distributors, subarterials and other higher-order traffic routes. Overseas precedents are noted and are linked to several Australian developments of the 1980s. This subject presents a challenge to the skill and flexibility of the traffic planner. (A)
