Review of Gazetted High Productivity Vehicle Route Network
High Productivity Vehicles (HPVs) were introduced into Tasmania to improve productivity in the transport sector and they have operated on Tasmanian roads since trials in 1993.
The current Tasmanian Gazetted HPV Route Network covers a large percentage of the State owned road network and extensive lengths of local roads. A number of sections are short connecting routes allowing access to depots and freight generators.
Significant sections of the current network were assessed using criteria relevant to shorter HPVs. Increases in vehicle lengths and weights since these original route assessments, as well as the desire to introduce Performance Based Standards for vehicles, has led to the development of new Tasmanian guidelines and this review of the current Gazetted HPV Route Network. Due to the differences in Tasmanian topography compared to the Mainland States, new Tasmanian geometric criteria, used in this review, were developed. These new criteria are based on the National Performance Based Standards (PBS), modified to suit Tasmanian conditions. The Tasmanian guidelines have been reviewed and endorsed by the Australian Road Research Bureau (ARRB).
The criteria used are based on:
- National guidelines for Performance Based Standards (PBS), adjusted to better fit Tasmanian conditions;
- Forestry Tasmania road construction manuals;
- Department of State Growth road construction specifications; and
- Other Australian jurisdictional requirements.
