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 (81.2% of today’s road for 2019). In 2025, 22 of the 49 count points were counted; DfT estimated the rest from earlier counts and local trends.
A77 collisions
Police recorded 224 collisions with the A77 as the first road from 2021 to 2025, 103 of them fatal or serious, including 11 fatal. That is 11.6 per 100 million vehicle miles, lower than the 31.5 for all A-roads in Great Britain. On average there were 0.5 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”.
