Question to the Department for Transport:

To ask the Secretary of State for Transport, on what proportion of all lane running smart motorways is computer analysis of CCTV images for stopped vehicle detection operational.

National Highways does not have computer analysis of CCTV images for stopped vehicle detection operational on any existing All Lane Running smart motorways. National Highways preferred approach is radar based stopped vehicle detection (SVD) technology, which is in place on all existing All Lane Running motorways. SVD is capable of detecting stopped vehicles in live lanes, automatically alerting drivers with ‘report of obstruction’ signs, and sending alerts to control rooms.

National Highways are currently reviewing the status of the 2020 technical report.
