2Road categories for temporary traffic management#

2.2Default TTM road categories#

Replace:

Category 1 (most urban streets and lower volume rural roads). The characteristics of category 1 roads are defined by the following parameters:

• Posted speed and AADT of:
• any speed limit with less than 3,000 vehicles per day AADT
• a speed limit of less than 60 km/h and traffic volumes between 3,000 and 10,000 vehicles per day AADT

with:

Category 1 (most urban streets and lower-volume rural roads) includes single carriageway roads with a posted speed limit of:

• less than 60 km/h where the Annual Average Daily Traffic (AADT) is less than 10,000, or
• 110 km/h or less where the AADT is less than 3000.

Replace:

Category 2 (high volume roads). The characteristics of category 2 roads are defined by the following parameters:

• Posted speed and AADT of:
• a speed limit greater than, or equal to 60 km/h and traffic volume greater than, or equal to 3,000 vehicles per day AADT
• any speed limit with traffic volumes greater than, or equal to 10,000 vehicles per day AADT
• Signalised intersections
• The characteristics of these roads are recognised as:
• multilane or divided roads
• high speed highways.

with:

Category 2 (high volume roads) comprises anything not in Category 1 or 3, and includes roads with:

• any signalised intersection
• multiple lanes in a single direction (excluding overtaking and turn lanes)

Replace:

Category 3 (expressways = high-volume & high-speed roads). The characteristics of category 3 roads are defined by the following parameters:

• These are high-volume expressways, or high-volume / high-speed multi-lane expressways with a divided carriageway
• Any expressway and any associated on-ramp or off-ramps
• Grade separated road with speed limit greater than, or equal to 90 km/h. Traffic volumes are generally greater than 20,000 VPD but can be lower

with:

Category 3 (expressways = high-volume & high-speed roads) includes:

• Expressways (that is, freeway, motorway or tunnel-type roads) and associated on-ramps or off-ramps, or
• grade-separated roads with:
• posted speed limit greater than or equal to 90 km/h, and
• AADT greater than 20,000.

2.4TTM road categories map for Queensland#

TTM road categories for roads across Queensland have been determined and are available on Queensland Globe. This map only shows Category 2 or 3 roads, with all other roads being Category 1. The TTM Road Categories map layer on Queensland Globe is accessible by following these steps:

• Click on 'Layers'.
• Click on 'Add Layers'.
• Scroll down to the 'Transportation' category and expand the layer list using the dropdown arrow.

• Select the 'Temporary traffic management road categories' layer by checking the tick box.

Please note that:

• A list of Local Government Authorities (LGAs) and their Queensland Globe map status is available on the QGTTM webpage. If no roads are displayed for the LGA in Queensland Globe, please check the LGA map status document and, if 'not included', contact the LGA directly, noting that only Category 2 and 3 roads are displayed on Queensland Globe. Additional road category information will be added to Queensland Globe by Transport and Main Roads for LGAs as this information becomes available.
• The road category layer is only visible at certain zoom levels, so navigate to your area of interest and zoom in to view the current TTM Road Categories.
• To enhance the visibility of the TTM category layer, deselect other road network layers and use the 'Queensland basemap grey' layer in place of the imagery layer. You can toggle them on and off as required.

If you are new to Queensland Globe, there is a range of tutorial videos available under the 'Help' section.

The TTM road categories map on the Queensland Globe will be maintained and updated by Transport and Main Roads periodically. Please email TrafficEngineering.Support@tmr.qld.gov.au with any requested changes for approval. The Traffic Engineering Practice team will forward any approved TTM road category changes to the Transport and Main Road's Corporate Mapping team for updating of the Queensland Globe maps.
