OS Open Roads

OS Open Roads is a connected road network for Great Britain. It contains all classified roads (such as motorways and A & B roads) as well as officially named unclassified roads. This update also displays motorway junctions. The product is part of the new OS Open products suite and is designed to be used with other OpenData sets. It’s mapping that can help you question, visualise and share results quickly and clearly. With OS Open Roads you can: Understand the road network at a ‘high level’ with generalised geometry and network connectivity. Identify locations and pin information, such as incident or accident hotspots. Display results in context using OS Open Map – Local mapping. Take an informed overview of a situation along the network to manage it strategically.
