Seasonally corrected Average Daily Traffic expressed as the number of Vehicles per Day. All RCA owned Carriageway Sections and Treatment Lengths are required to have an ADT or AADT Estimate. Carriageway Sections and Treatment Lengths where a Count has taken place will also have an ADT Count recorded.
Asset Owner
All assets in RAMM can be assigned an Owner. The list of Asset Owners can be maintained by the RCA but must be associated with one of three Asset Owner Types (Local Authority, Crown, or Private). The Performance Measures check for assets where the Type of the Asset Owner is set to L for Local Authority (or C in the case of the State Highway RCA).
Average Daily Traffic (ADT)
Average number of Vehicles recorded at the Count Site calculated to be the number of Vehicles per Day. All RCA owned Carriageway Sections and Treatment Lengths are required to have an ADT or AADT Estimate. Carriageway Sections and Treatment Lengths where a Count has taken place will also have an ADT Count recorded.
C
Carriageway Section
A homogenous section of the Road usually identified using geographical boundaries or dimensional change points such as intersections, landmarks, lane changes, etc.
Homogenous means a section of road with the same network, sub-network, width, number of lanes, traffic volume, pavement type, and classification (ONRC, Urban/Rural, etc).
a.k.a. Road Section
Carriageway Surface
A record of the surface which has been laid down on the Road.
Carriageway Width
The Carriageway Width is the average seal edge to seal edge distance along the length of the Carriageway Section for a sealed road and the average width of the formed unsealed surface.
Condition
The Condition of an asset describes how fit it is to serve its purpose. A range of aspects of the condition of the Road, including cracking, potholes, etc. are manually rated and recorded in RAMM.
Corridor
Corridor is a tool for managing the asset across a journey from origin to end destination.
Cost Group
Maintenance Costs are categorised by Cost Groups which are used to group remedial Activities and Faults and indicates the broad area or asset group where the work has taken place. Relevant areas in the context of Transport Insights are Pavement (PA) and Surfacing (SU).
Crash Analysis System (CAS)
The Crash Analysis System is the record of all Crashes in New Zealand and is owned and maintained by Waka Kotahi. RCAs must load their prepared CAS data into their RAMM database. There can be a delay before Crashes appear in CAS and then RAMM. Only Crashes for years with complete data through to June 30th are included in the Transport Insights reports.
Crash Data
Information on Crashes is extracted from CAS and prepared for import into RAMM. Each RCA has details of all Crashes occurring within their boundaries available in their RAMM database.
E
End Displacement
All assets are located on the network by reference to their distance from the start of the Road (location or start displacement). Where an asset has a length, then the displacement of the End of the asset is recorded in metres from the start of the Road.
F
Financial Year
The Local Government Financial Year runs from July 1st to June 30th. This is represented in Transport Insights using the format ccyy/yy, for example 2016/17.
H
High Speed Data (HSD)
This is a specialised method of measuring properties of the condition of the Road using specialised equipment mounted on a vehicle moving at close to normal operating speeds. Amongst the information collected using this method is Roughness.
L
Lane Kilometres
Lane Kilometres is a method of defining the size of a network or a portion of a network. In the context of Transport Insights, the Lane Kilometres are calculated from the length of the Carriageway Sections within the classification multiplied by the number of Lanes recorded on each Carriageway Section.
Latest Process
RAMM keeps a history of all the Condition Rating and High Speed survey data recorded over time. Therefore, to simplify reviewing this data all records are flagged as either being the Latest (most recent) or Not Latest (historical) information at that location based on their assessment date.
The Latest process is available for each of the types of Condition Surveys as one of the Status Check processes.
Length of Network
The Length of the Network is a measure of the size of the Road Controlling Authority’s network. It is usually calculated from the sum of the Length in metres recorded for each Carriageway Section.
Local Authority
The Territorial Local Authorities are the second tier of local government. In the context of Transport Insights they are the organisations which are responsible for the Roading network.
Location
Assets which do not have a length are located at a single point on the Road. The displacement (in metres) from the start of the Road of this single point is known as the Location of the asset.
M
Maintenance Cost
Routine Maintenance Costs are recorded in RAMM both as the actual invoiced value plus an RCI adjusted cost. Maintenance Costs are categorised by Cost Groups which are ways of grouping together related costs. Some of the Performance Measures make use of Routine Maintenance Costs from the Pavement (PA) and Surfacing (SU) Cost Groups.

One Network Framework (ONF)
The One Network Framework is New Zealand's new national classification system. It will be used to determine the function of roads and streets, and inform decision making. The new One Network Framework acknowledges the transport network has a Place function. This means roads and streets are destinations for people, as well as transport corridors. The new framework also introduces classifications for different modes of transport, recognising that our roads and streets have different functions for different modes.
One Network Road Classification (ONRC)
This is a system designed by the subject experts in the Te Ringa Maimoa Transport Excellence Partnership to standardise the performance of roads throughout New Zealand.
Original Cost
Assets in RAMM can have the Original Cost recorded against them. The Original Cost is the total cost of supplying the asset at the time it was constructed or installed. The Original Costs for Resurfacing (Work Category 212) and Pavement Rehabilitation (Work Category 214) are reported in ONRC Performance Measures. Both surfacing and pavement Original Costs for 212 and 214 are to be recorded against the Carriageway Surface records.
Owner Type
Carriageway Sections are assigned one of three possible Owner Types (Local Authority, Crown, or Private). This flag is used when calculating which Carriageway Sections contribute to the network owned by the RCA.
P
Pavement Layer
The Pavement Layers are put down above the sub-grade and supports the Carriageway Surface.
Pavement Structure
RAMM uses the Pavement Structure Generation process to create views of the Pavement Layers, still in service, which reflect the Carriageway Sections or the major properties that they give to the Road.

Road Section
a.k.a. Carriageway Section - A homogenous section of the Road usually identified using geographical boundaries or dimensional change points such as intersections, landmarks, lane changes, etc. Homogenous means a section of road with the same network, sub-network, width, number of lanes, traffic volume, pavement type, and classification (ONRC, Urban/Rural, etc).
Road Type
RAMM allows Roads to be categorised using the Road Type indicator. Using this flag it is possible to indicate if the RAMM Road is to be considered a Local Authority Road, a State Highway (Crown Road), or a Private Road. This flag is also used to indicate other definitions such as Car Parks or Parks and Reserves.
Roughness
Roughness is an indication of the condition of the Road surface. It is a measure of irregularities in the longitudinal profile of one or two wheelpaths in a traffic lane.
S
Sealed Area
The Sealed Area is the portion of a Carriageway Section or Treatment Length which is sealed, expressed in square metres.
Smooth Travel Exposure (STE)
The Smooth Travel Exposure is a measure of the quality of the Road calculated from the Roughness data. The higher the percentage of STE then smoother the network.
Start Displacement
All assets are located on the network by reference to their distance from the start of the Road. Where and asset has length then the displacement of the Start of the asset is recorded in metres from the start of the Road.
Status Check
Status Check is the collective name for a range of background processes in RAMM. These process perform tasks such as setting the Latest flags on Condition data, creating the Pavement or Surface Structure views, and summarising information to Treatment Lengths.
Surface Function
This is a flag on the Carriageway Surface record to indicate whether the Surface is a First Coat, a Second Coat, or a Reseal.
