Average And Indicative Speed

This feature type provides two sets of speed information for all roads in Great Britain. These are:

A historic average speed in kilometres per hours (kph). In this context, 'historic' means that the average speed data was collected over a six-month period for the selected road link. Average speeds are provided in different time periods for each road link. A single day (i.e. a 24-hour period) is split into 8 time periods Monday to Friday (MF) and 6 time periods Saturday to Sunday (SS), for example, Monday–Friday (MF) 07:00–09:00, Saturday–Sunday (SS) 14:00–19:00. There’s a separate attribute for each time period. For Road Links that can be traversed in both directions, In Direction and ‘againstdirection’ attribute values are populated for average speed. For one-way Road Links, only one of these attributes will be populated, dependent on the directionality of the Road Link. For example, if Road Link directionality = In Direction, then in direction speed will be populated, whereas if Road Link directionality = In Opposite Direction, then against direction speed will be populated.
An indicative speed limit. This is an indication of the maximum speed limit for vehicles; the indicative speed limits reference road network data. Indicative speed limit values that apply over the majority of a section of road are provided in both miles per hour (mph) and kilometres per hour (kph).

Temporal filtering

The earliest date on which you can request a one-off snapshot of a date in the past for data in this feature type is 28 March 2023.

Annual Full Supply option

Please note that if you select Annual Full Supply with an initial supply date of 01 Jan 2023 as the update frequency for a data package containing this feature type in OS Select+Build, this will result in you receiving an empty data package. This is because the data for this feature type was only made available in the OS NGD from 28 March 2023. The Full Annual Supply option for data from this feature type will become available from 01 January 2024.

Feature type attributes

The following sub-sections provide details about the attributes included with this feature type, their data types in the different output formats, and other important metadata about them.

osid

Primary identifier for the feature. The OSID is a Globally Unique Identifier (GUID) and requires no centralised authority to ensure uniqueness. Note that the same OSID can occur in more than one feature type when a single feature is represented multiple times in the OS NGD. The OSID is populated from the Road Link to which the speeds relate, and therefore the same OSID is present in both feature types.
