The article describes the results from a large scale study about the traffic safety effect from implementing one-way bicycle paths in build up areas in medium and large town in the western part of Denmark. The study was a before and after study with a comparison group and consisted of 40 km of road distributed on 46 road segments. On these roads, bicycle paths were implemented between 1st January 1989 and 31st December 2000.  In general, implementing of bicycle paths resulted in an insignificant increase in the number of injury accidents by 14%. It was mainly caused by a statistical significant increase in the number of injury accidents with vulnerable road users i.e. moped riders, cyclists and pedestrians with 25%. The number of injury accidents that involved vulnerable road users did increase significantly at intersections (34%) while the effect on sections was small and uncertain. The effect in the intersections was the worst for moped riders with a tendency to statistical significant increase with 94%, while a similar but lower trend has been observed for cyclists and pedestrians.
