A highways engineer built a routing tool that scores roads by five years of crash data
He works with collision data as a UK highways engineer but could never answer the simple version for his own commute: which route has actually hurt people. He built SafeRoute with AI, which plans a route and scores it on five years of collision records; colleagues then asked for the same data as branded evidence reports for committees, which the tool now produces in about 30 seconds instead of a day of manual work.
How it works
- Build route planning with AI
- Score routes on collision density with severity weighting
- Fix scoring so the least bad route is not labelled safe
- Colleagues request committee reports
- Reports generated in about 30 seconds
Why it’s worth knowing
His scoring fix is the record: a route only counts as safer if it beats the default by a real margin, not because it is the best of a bad set.
