Segments - Location Details Tab¶
Road Measurements¶

Average Segment Width is a mandatory, user entered value denoting the average width of the segment.
Measured Segment Length is a non mandatory, user entered value denoting the length of the segment.
System Generated Length is a read-only field showing length of the segment as calculated by the system.
The data grid shows users the calculated width values for this segment from data entered via the Width Module and the data gathered via Mechanical Data surveys. The Avg. Width (m) values are weighted by coverage.
Location¶
Engineering Area
Mandatory selection of an Engineering Area from LA specific dropdown of possible values.
Licensing Area
Mandatory selection of a Licensing Area from LA specific dropdown of possible values.
Municipal District
The Municipal District the segment is within. Set automatically on selecting edges.
Starts At/Ends At
Road segments have “Starts At” and “Ends At” fields, with a text description of where the road starts and ends. These labels are based on the node labels found at the start and end of the segment. When a road segment is made up of multiple edges, the start and end can be easily defined by clicking on the start edge first. Any label for the unattached node on the start edge becomes the “Starts At” description, and the unattached node on the last edge is used for the “Ends At” description. These descriptions appear on the Segments Form and in some reports.
When only one edge is used to create a segment however, the start and end nodes are defined by the line direction (which is set when the OSi digitised the line). The OSi Prime2 data model specifies that start nodes should be at the junction with the trunk road, and end nodes to be at the unattached end of an edge.
This however is not always the case as shown in the example below.

PMS provides a “Flip Start and End” checkbox to allow a user to switch which nodes are used for the start and end of the road. For unattached roads these will be reported back to the OSi for correction, in the meantime the user defined ends will be used throughout the system.

In some cases segments made up of one edge will be attached at both ends. In this case there is no defined “start” and “end”, so the user is free to switch them as they see fit.
