Main Road - A Main Road is a road, declared as a main road under an act of parliament, and controlled by the State Government Department responsible for roads.
Maintenance Grading - The term Maintenance Grading is used to describe the grading of unsealed roads. It is very similar to, and is sometimes used interchangeably with the term Patrol Grading. If there is a difference between the two terms it is probably that maintenance grading is a more scheduled activity where the whole of the road is graded irrespective of condition, and that patrol grading is seen as more of a go out and look for problems and fix them when you find them activity.
Major Collector Street - A major collector street is a street that collects traffic from surrounding access streets and/or minor collector streets and carries traffic volumes between 3000 - 6000 vpd.
Median - A median or median strip is a (typically) raised central strip which separates opposing lanes of traffic on a divided road.
Minor Collector Street - A minor collector street is a street that collects traffic from surrounding access streets and carries traffic volumes of up to 3000 vpd.
Mitre Drain - A mitre drain (also offshoot drain) is an open drain designed to divert runoff from a table drain or road shoulder away from a road.

Pavement Condition Index - A Pavement Condition Index (PCI) is a numerical score given to a road pavement to represent its condition.
Pavement Deformation - Pavement deformation is the change in a road surface from the intended construction profile.
Pavement Integrity Index - Pavement Integrity Index (PII) is a combined index of the pavement faults in sealed road surfaces used widely in New Zealand. It is a ‘weighted sum’ of the pavement defects divided by total lane length. PII combines surface faults (CI) with rutting and shoving.
Pavement Management System - A Pavement Management System is a software system designed to manage road seals & pavements. A system typically uses road hierarchy & condition information and to produce suggested optimal maintenance and reconstruction programs.
Pavement Marking - Pavement Marking or Road Marking is any markers, lines, words or symbols painted on or affixed to a road surface designed to instruct or assist motorists and/or the process of creating those marks.
