While timeframe impacts may appear within the realms of reasonability for permit holders, it does not capture every impactful scenario, particularly when the NHVR wishes to transition to a PAN and, therefore, a pre-approved network for permit application. Multiple road managers updating and amending the same pre-approved network at different instances in time will have an effect on existing permit processes where the permit is being renewed or amended
Mapping Symbology
The National Network Map (NNM) utilises a traffic light system to display road access. Road managers apply this traffic light system, based on heavy vehicle access, against all or portions of their nominated road network. The applied traffic light system ensures a consistent understanding aligned against traffic law, with Green as Approved (Go), Yellow/Amber as Conditionally Approved (Hazard or Cautions), and Red as Restricted (Stop). This method of displaying the various authorised networks is relatively simple and easy to utilise; however, this symbology is sufficient for pre-approvals. The traffic light colours on the map are for 'as of right" access under the gazette, whereas the pre-approvals (PANs and PARs) require a permit. A decisive way to produce and display this information in the simplest form is needed. Using a single colour for the pre-approved road access with a function to expose the pre-approved road access status with clear visual indicators that this is not a gazetted network.
