OS MasterMap Highways Network - Routing and Asset Management

Great Britain's most complete, detailed and accurate road network dataset.

For vehicle routing and navigation software providers, this data gives you all you need to get your users safely to their destinations: turn, height, weight and width restrictions – and even bollards and traffic calming.

Our asset management information allows highways teams to improve planning schemes in the office, avoiding unnecessary site visits. It can also identify potentially difficult locations, so you can organise required permits in good time.

All the details your teams need are right at their fingertips. If a water leak is reported, our data allows you to find the property, street and nearest hydrant so the impact on nearby properties is assessed, while determining the risk to other assets.

Comprehensive and authoritative

OS MasterMap Highways Network - Routing & Asset Management includes our highly accurate road network geometry. And with speed data now available, you can now access data on road speed limits and average speed times, helping you plan routes and analyse traffic information.

Driving navigation for the future

Thanks to the full road geometry and connectivity you’ll find in OS MasterMap Highways Network - Routing & Asset Management, it’s ideal for use in routing software solutions and sat-nav devices; it also underpins the telematics technology needed by driverless vehicles.

Sweat your assets

Since OS MasterMap Highways Network - Routing & Asset Management dovetails with OS MasterMap Topography Layer, you’ll understand precisely how roads, land and buildings exist together. This helps you make efficiency gains through insights into how capital assets can be better managed.

Delivery and reporting

Knowing turn information is half the battle when it comes to planning delivery routes. With OS MasterMap Highways Network we have gone beyond just the restrictions with detailed information about narrow roads and pinch points. The data can join up an organisation's common reference to roads and help make informed decisions around the road quickly and effectively.
