Motorway Incident Detection and Automatic Signalling (MIDAS) is a sensor based network along UK motorways, and is designed to collect data regarding traffic flows, average speeds and road occupancy, amongst other features, on the road network. This data can be accessed via the MIDAS website https://www.midas-data.org.uk/ (login required) in the form of .tcd.bz2 files.
