Gera Traffic Pressure Index — Road Traffic Stress in England
153 English local authorities · DfT AADF 2025 · OGL v3.0
Which English local authorities have the highest road traffic pressure in 2025?
As of 2025, Thurrock has the highest Gera Traffic Pressure Index in England at 6.5/10 — rank 1 of 153 local authorities. Its HGV freight share is 12.6%, the national average GTPI is 3.4/10. The index combines 10-year AADF growth, HGV share, and count-point density from DfT open data; no other source publishes this composite.

Highest HGV freight share: up to 13.1%
HGV share varies widely across English local authorities — from under 2% in urban London boroughs to over 13.1% in industrial logistics corridors like North Lincolnshire and Thurrock. High HGV share is associated with road noise, air quality impact, and infrastructure wear.

Frequently asked questions
- What is the Gera Traffic Pressure Index?
- The Gera Traffic Pressure Index (GTPI/10) is a per-local-authority score combining three signals from DfT road traffic statistics: (1) 10-year AADF growth trend (weight 40%), (2) HGV freight share of all motor vehicles (35%), and (3) count-point density per 100km of road (25%). Each sub-score is min-max normalised across 153 English local authorities. The national average is 3.4/10.
- What does AADF mean?
- AADF stands for Annual Average Daily Flow — the average number of vehicles passing a given point on a road during a 24-hour period, averaged across all days of the year. DfT collects AADF data at over 46,000 count points across Great Britain using a combination of manual counts and automatic counters.
- Why does HGV share matter for renters?
- Heavy goods vehicles (HGVs) are disproportionate contributors to road noise, vibration, and air quality degradation. Areas with high HGV share (e.g., logistics corridors, port areas, motorway junctions) often have poorer residential amenity for noise-sensitive renters. The national HGV share ranges from 2.0% to 13.1% across English local authorities.
- Where does the data come from?
- DfT Annual Average Daily Flow (AADF) data, dft_traffic_counts_aadf.csv (600,000+ count-point records, 2000–2025), and DfT local_authority_traffic.csv. Both published under the Open Government Licence v3.0 at roadtraffic.dft.gov.uk/downloads.
