Closest roads

This method returns the closest roads.

UK roads fall into the following categories:

• A roads – major roads intended to provide large-scale transport links within or between areas.
• B roads – roads intended to connect different areas, and to feed traffic between A roads and smaller roads on the network.
• Motorways - a high-capacity road with multiple lanes in each direction, controlled access points, and a separation between opposing flows of traffic, typically identified by the letter "M" followed by a number (e.g., M1, M25).
• Classified unnumbered – smaller roads intended to connect together unclassified roads with A and B roads, and often linking a housing estate or a village to the rest of the network. Similar to ‘minor roads’ on an Ordnance Survey map and sometimes known unofficially as C roads.
• Unclassified – local roads intended for local traffic. The vast majority (60%) of roads in the UK fall within this category.
