Latest Speed Limits

This map layer displays the current speed limit for every section of road, based on a combination of default speed limits, and additional byelaws etc. The layer takes the default speed limits for each road segment, and then adds all later speed limits on top of this.

The following rules are used for calculating the latest speed limit:

  • If no “Date Commenced” has been set for a speed limit then it defaults to 1900-01-01

  • Cautionary and Proposed speed limits are ignored when calculating the latest speed limits for a road

  • Any speed limits that have expired are ignored in the Expiry Date is before the date the report was last calculated

Data for this layer is added to the system via the Speed Limits Form.

This layer is found under the Latest Surveys folder of the layer tree.

The WMS/WFS name for this layer is SpeedLimitSurvey.
