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 (87.1% of today’s road for 2019). In 2025, 2 of the 20 count points were counted; DfT estimated the rest from earlier counts and local trends.

A523 collisions

Police recorded 126 collisions with the A523 as the first road from 2021 to 2025, fewer than 3 of them fatal or serious, including 7 fatal. That is 19.0 per 100 million vehicle miles, lower than the 31.5 for all A-roads in Great Britain. On average there were 0.8 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”.
