OS MasterMap Highways Network With Speed Data Technical Specification
This technical specification provides detailed technical information about OS MasterMap Highways Network With Speed Data. It is targeted at technical users and software developers.
The OS MasterMap Highways Network family has been enhanced with the addition of three new products:
OS Master Highways Network with Routing and Asset Management Information and Average Speed
OS Master Highways Network with Routing and Asset Management Information and Speed Limits
OS Master Highways Network with Routing and Asset Management Information and Average Speed and Speed Limits
These three new products are supplied with an additional data file which will be either Average Speed, Speed Limits or a combination of both. This Technical Specification will cover the elements which make up the Average Speed and Speed Limits data files. Please see the OS MasterMap Highways Network – Routing and Asset Management Information (RAMI) Technical Specification for more information about this product.
OS MasterMap Highways Network with Average Speed contains detailed historical speed information which provides the average speed travelled for all roads in Great Britain. This dataset is based on a year’s worth of information collected by in-vehicle telematics devices that capture data for all roads.
OS MasterMap Highways Network with Speed Limits identifies the speed limit for a stretch of road based on road traffic signs. This dataset is sourced from local authorities, police forces and many other reliable sources to ensure a high level of accuracy. The data is continuously updated through a system of user feedback.
Both Average Speed and Speed Limits data are linked to the corresponding OS MasterMap Highways Network Road Link feature to which it belongs, identified by the Road Link TOID.
These speed datasets will be made available along with the OS MasterMap Highways Network – Routing and Asset Management Information (RAMI) product licence.
Available formats
OS MasterMap Highways Network with Average Speed dataset will be supplied as a Comma-Separated Value (.CSV) file.
OS MasterMap Highways Network with Speed Limits dataset will be supplied as a shapefile (.shp), for which the source projection is OSGB 1936 / ESPG 27700, British National Grid.
