Roads: Accidents
(asked on 13th June 2018) - View Source
Question to the Department for Transport:
To ask the Secretary of State for Transport, what assessment he has made of the effect of the installation of smart motorways on the level of road traffic accidents in each of the last three years.
England’s motorways are among the safest roads in the world and each smart motorway scheme should be at least as safe as the traditional motorway it replaces.
Over the last three years, Highways England have focused their assessment of the effect of the installation of smart motorways on the level of road traffic accidents through a detailed review of the operational M25 schemes, which has demonstrated that the safety objectives set for these all lane running smart motorways have been met, as set out in the following table:
M25 Smart Motorway Monitoring reports
Smart Motorway Scheme | Scheme open | Road traffic accident rate before (2011-14) (accidents per million vehicle miles) | Road traffic accident rate after 1 year (2014-15) (accidents per million vehicle miles) | Road traffic accident rate after 2 years (2015-16) (accidents per million vehicle miles) | Road traffic accident rate after 3 years (2016-17) (accidents per million vehicle miles) |
M25 J5-6 | 2014 | 13.146 | 10.13 | 9.610 | 9.329 |
M25 J23-27 | 2014 | 12.871 | 10.369 | 11.502 | 11.234 |
