This collection provides detailed network and extent data for transport routes across Great Britain. It supports routing, asset management and transport planning, with topologically structured datasets, and authoritative identifiers.
Transport networks data
Data about roads, paths, trams, ferries and railways
What is transport networks data?
Features of transport networks data
Road networks
Road network data, integrated with authoritative local gazetteers, provides accurate road geometry and identifiers for planning and emergency response.
Routing and hazard intelligence
Perform travel time and risk analysis with average speed data, and identify routing hazards such as low bridges, turn restrictions, and vehicle limitations, to support risk-aware route planning.
Asset management
Quickly identify protected streets, associated conditions, which authority is responsible for a street, and how it should be restored following works.
Active travel mapping
Visualise and analyse paths and cycleways with surface type and function attributes to support active travel policies, route optimisation, and recreational planning.
Street-level and lighting insights
Visualise streetlights coverage, to support safe route planning, and infrastructure development such as identifying opportunities to repurpose streetlights.
Multi-modal network integration
Explore seamless connectivity across road, rail, path, and ferry networks to support journey planning, freight logistics, and sustainable transport strategies.
