Road traffic estimates (TRA)

The Department for Transport (DfT) publishes estimates of Heavy Goods Vehicle (HGV) traffic within the road traffic statistics. We are seeking users’ views on a change to how HGV data is collected for road traffic statistics. From 2028, roadside counts of HGV traffic will be simplified into two categories: rigid and articulated vehicles. This change will not affect the information available on total HGV traffic within the published summary statistics.  It will impact the level of disaggregation available for HGVs by number of axles in the count point level data that is available to download via the road traffic geographic website and API.

We invited users to provide comments on the proposed change by 31 August 2026. The findings will be published in due course.

The department is currently working to make our tables accessible for our users. The data tables for these statistics are now accessible.

We would welcome any feedback on the accessibility of our tables, please email road traffic statistics.
