What to do with this: if your regular routes cross the junctions above, they deserve extra care at peak times — these aren’t random locations, they’re where collisions repeat. For context, Cambridge’s rate of 199 per 100,000 residents compares with an average of 220 across the 125 areas we track. And if you’re ever hit at one of these spots, that documented history is relevant to liability — mention it when you call.
Vulnerable road users in Cambridge in 2025: 35 collisions involved a pedestrian, 134 a cyclist and 31 a motorcyclist — overall, 198.6 collisions per 100,000 residents.
Area definition: figures cover 6km radius of the town centre. Per-100k rates use the mid-2023 ONS population estimate for the named town or district; where the area is radius-defined, treat the rate as indicative.
These figures come from the Department for Transport’s STATS19 dataset — every collision reported to the police in 2025 — clustered to roughly 100 metres and labelled via OpenStreetMap. Only police-reported incidents are included, so minor damage-only bumps are undercounted. See the full UK hotspots analysis for the national picture and methodology.
