Vehicles a day is the average daily flow in 2025. “Since 2019” compares the same count points. Collisions are those with the A657 as the first road, placed on the nearest section by their recorded position; rates (per 100 million vehicle miles) are shown for sections of half a mile or more with 10 or more.

A657 traffic by vehicle type

Cars and taxis make up 84.1% of the vehicle miles on the A657. HGVs account for 1.6%.

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, 2 of the 5 count points were counted; DfT estimated the rest from earlier counts and local trends.

A657 collisions

Police recorded 110 collisions with the A657 as the first road from 2021 to 2025, 28 of them fatal or serious. That is 41.1 per 100 million vehicle miles, higher than the 31.5 for all A-roads in Great Britain. On average there were 2.6 a year for each mile of road.

  • 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”.
