Organisation: Office of Rail and Road (ORR)

Uploaded to Knowledge Centre: 29 September 2021

This report comprises an independent review by the Office of Rail and Road (ORR) of the data concerning the safety of all lane running motorways.

The report was provided for the Secretary of State for Transport in response to his request to ORR in March 2021 to undertake quality assurance of the data and evidence underpinning the conclusions arrived at regarding all lane running (ALR) motorways.

It specifically addresses the following questions:

• Are the data and evidence used in the stocktake and the progress report reliable and robust and in line with established/best practice?

• Have comparisons been made in an appropriate way about the relative safety of ALR motorways, with reference to conventional motorways and other roads?

• Are there any other data that could be used to enhance understanding of the relative safety of ALR motorways or to support the monitoring and evaluation of the effectiveness of the measures we are putting in place to improve safety and perceptions of safety?

• Are there data and evidence available which can compare the international experience of operating similar types of road?
