The chart counts the whole road as it was each year, so new or renumbered stretches move it. The percentage changes compare only count points present in both years. In 2025, 5 of the 24 count points were counted; DfT estimated the rest from earlier counts and local trends.
A104 collisions
Police recorded 724 collisions with the A104 as the first road from 2021 to 2025, 133 of them fatal or serious, including 3 fatal. That is 180.8 per 100 million vehicle miles, higher than the 31.5 for all A-roads in Great Britain. On average there were 10.7 a year for each mile of road.

|---|---|---|---|---|
| Traffic counts and vehicle mix | Road traffic statistics (AADF by count point) Department for Transport Derived statistics UK Motoring | 2000 to 2025 | 24 count points in 2025 | 15 September 2026 |

- Annual average daily flow (AADF) is the average number of vehicles passing a point on a typical day of the year, both directions combined.
- Vehicle miles are AADF multiplied by link length and 365, summed over every count point link on the road.
- Sections join count point links between junctions, using the link lines in DfT’s major road database.
- STATS19 covers personal injury collisions reported to the police. Damage-only collisions are not included, and not every injury collision is reported.
- Serious and slight figures are DfT’s adjusted estimates, which allow for police forces moving to injury-based reporting.
- Counts of one or two collisions below Great Britain level are shown as “fewer than 3”.
