Coaches and road safety

The Royal Dutch Association of Transport Companies (KNV) asked SWOV to compare the safety of travelling by coach with travelling by other modes of transport.

Research questions

The following KNV-questions were investigated in the study:

  1. What are the road safety differences between the modes of transport train, public transport bus, coach and car, at the national level and , if possible, at the international level?
  2. What are the road safety difference between the transport modes coach and airplane at the international level?
  3. What is de impact of coaches on the numbers of road deaths and serious road injuries in traffic?
  4. What are the possible causes of a crash involving a coach (technique, driver, other road user, etc.)?
  5. Does the use of coaches implicitly contribute to road safety because it reduce the number of cars on the road?


SWOV handled these question using available data sources in SWOV report Touringcars en verkeersveiligheid (Coaches and road safety). The available data was insufficient to distinguish between public transport buses and coaches. SWOV therefore compared the road safety of the umbrella category ‘buses’ with that of (passenger) cars.
