Operation Road Classification

This takes into account traffic volumes generated by large areas of population, commercial ventures, through traffic and/or tourist attractions etc. 
 
Operational Class 199 – Generally Arterial Roads – Route carrying a main flow with many branches
Roads with a traffic count generally more than 150 vehicles/day and are generally bitumen sealed. They are through roads which connect to significant destinations and carry a main flow with a significant number of feeder roads. The running surface is generally 6.5 – 8.0 metres wide [including shoulders]. They should be formed and generally drained to meet Q2 to Q5 standard, however, significant rain events may cause temporary closure.

Operational Class 150 – Generally Major Collector Roads – Collects from local access roads to distribute to an Arterial Road
Roads with a traffic count generally between 125 - 150 vehicles/day. Roads which can be either bitumen sealed or gravel or are a combination of both. They are generally through roads which connect to significant destinations and collect from local access roads to distribute to an arterial road. The running surface is generally 6.5 metres wide [including shoulders] for both sealed and unsealed roads. They should be formed and generally drained to meet Q1 standard, however, significant rain events may cause temporary closure.

Operational Class 125 – Generally Minor Collector Roads – Collects from a limited number of local access roads to distribute to an Arterial or Collector Road
Roads with a traffic count generally between 100 - 125 vehicles/day. Roads which can be either bitumen sealed or gravel or are a combination of both. They are generally through roads and collect from a limited number of Local Access roads to distribute to an Arterial or Major Collector road. Total pavement width is generally 6 metres wide including bitumen seal as applicable. They should be formed and generally drained to meet Q1 standard, however, significant rain events may cause temporary closure.

Operational Class 100 – Generally Local Access Road – road to access properties where people actually reside or provides exclusively for one activity or function
Roads with a traffic count generally between 75-100 vehicles/day. Roads which can be either bitumen sealed or gravel or are a combination of both. They are mainly “no through” roads, providing access to properties where people reside. They may also provide exclusive access for one activity or function. Total pavement width is generally 5.5 metres including bitumen seal as applicable. The pavement material may be either imported gravel or insitu material. Maintenance activities on these roads are intended to keep them trafficable in the majority of weather conditions, however it is possible that water may cross the road in minor storm events and that the interval between treatments may be less than desired.

Operational Class 75 –Generally Minor Local Access Road – Road to access limited properties where people actually reside
Roads with a traffic count generally between 30-75 vehicles/day. They are generally unsealed “no through” roads providing limited access to properties where people actually reside. They may also provide exclusively for one activity or function. Total pavement width is generally 5 metres and may be made up of either imported gravel or insitu material.
Maintenance activities on these roads are intended to keep them trafficable in the majority of weather conditions, however it is possible that water may cross the road in minor rain events and that the interval between treatments may be greater than 12 months.

Operational Class 30 – Generally Service Track – Provides access to properties and property related activities
Roads with traffic count generally between 10-30 vehicles/day. Roads which are generally unformed and undrained and are made up of a combination of imported gravel and naturally occurring material. They provide access to one property. The width of the running surface is generally 4 metres and maintenance activities on these roads are intended to keep them open to traffic, however it is probable that water may cross the road in minor rain events and that the interval between treatments may be greater than 18 months.

Operational Class 10 – Generally Track – Provides access to properties and/or recreational facilities
Roads with infrequent traffic use and less than 10 vehicles/day. Roads which are “no through” roads and are open to the public. These roads are unformed and undrained and their make-up consists of naturally occurring material. They are generally unfenced. Maintenance activities on these roads are intended to keep them open to suitable vehicles, however it is probable that water will cross the road in minor rain events and that the interval between treatments may be greater than 2 years.
