Road Risk Score
Cambridge ranks 64 of 125 towns we score — band C, around average
50 people killed or seriously injured per 100,000 residents, 109.6 vehicle crimes per 100,000, 69% of collisions involving someone outside a car, and a five-year trend of -7.1%. How the score works.
Vulnerable road users in Cambridge (2025)
35 of Cambridge's 290 collisions (12%) involved pedestrians; 134 of Cambridge's 290 collisions (46%) involved cyclists; 31 of Cambridge's 290 collisions (11%) involved motorcyclists. Together those collisions left 52 people killed or seriously injured.
| Road user | Collisions | Share of all collisions | Killed or seriously injured | Serious-outcome rate |
|---|---|---|---|---|
| Pedestrians | 35 | 12% | 10 | 29% |
| Cyclists | 134 | 46% | 29 | 22% |
| Motorcyclists | 31 | 11% | 13 | 42% |

Cambridge’s busiest collision clusters (2025)
Each circle is a ~100m cluster of police-reported collisions. Larger circles = more collisions; red = at least one death. Click a circle for details.

Cambridge’s junctions that stay dangerous
These locations recorded multiple collisions in at least four of the last five years (2021–2025) — a persistent pattern, not a one-off bad year.

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. A junction with a documented five-year history is also the strongest evidence a campaign can put in front of a councillor.
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.
Need this cut a different way? A junction’s full history, cyclist or pedestrian casualties on their own, or a before-and-after on a scheme: we produce those, free for community groups, campaigners and journalists.

Cambridge's roads are Cambridgeshire's responsibility
Collisions above are counted for Cambridge. The body that maintains those roads, sets the speed limits and decides which junctions get fixed is Cambridgeshire — so that is the level at which the record can be compared with anywhere else in Britain.

Those two numbers disagree, and that is the story. Cambridgeshire sits 57 of 188 measured per resident but 128 of 192 measured per mile actually driven — a gap of 71 places. Measured against the traffic the network actually carries rather than the number of people living beside it, the record is better than the headline per-head figure implies.
The full record for Cambridgeshire — severity-adjusted casualties, the breakdown of who is being hurt, the darkness and ice profile, and a comparison against its ONS statistical neighbours rather than the national average — is on its own page.
Cambridgeshire’s full road risk record →What actually changes the odds in Cambridge
Data is only useful if it changes what you do. These three are picked from Cambridge’s own figures above, each with the number that prompted it. Every guide explains how the thing works before it suggests buying anything, and most cost less than a third of a typical insurance excess.
Helmet camera
£50–£200
46% of collisions in Cambridge involve someone on a bike. In a disputed pull-out, footage from the rider's viewpoint is what settles liability.
How it works →
Alarmed disc lock
£20–£50
Motorcyclists are in 11% of Cambridge's collisions, and bikes are also lifted rather than ridden away. An alarmed disc lock covers the theft half for about £30.
How it works →
Faraday key pouch / box
£9–£25
Even at Cambridge's 110 vehicle crimes per 100,000 residents, relay theft is the method that needs no tools and leaves no damage. The pouch is the cheapest thing that stops it.
