In-depth insight in crashes involving slow motorized traffic

In-depth study to identify the factors that play a role in the occurrence and outcome of crashes involving slow motorized vehicles. The vehicles that are included in this study are the light moped, the microcar and the mobility scooter.

Research questions

  1. How did the crash occur?
  2. Which combination of factors relating to man, vehicle, and road played a role in the crash occurring?
  3. Which combinations of factors are frequent?


The variation in two-wheelers using the bike path is considerable. A study in Amsterdam showed that a disproportionate share of the light moped crashes occurs on the bike path. This may in part be due to the amount of traffic on the bike path and the variation in speeds, but other factors may also play a role. Identifying the most appropriate measures requires a better insight in the development of crashes on the bike path involving light mopeds. Furthermore, the continued ageing of the population leads to increased use of microcars and mobility scooters, which in its turn, results in more crashes involving these vehicle types. There is still little insight in the influence of, for example, vehicle structure (stability and protection against impact), behavioural factors and infrastructural facilities for these vehicles. Again, in relation with these issues more insight is needed into the factors that play a role in crashes involving mobility scooters and microcars to be able to determine the correct measures. An in-depth study has been chosen to gain more insight.

A SWOV in-depth study uses the following method:  for each relevant crash that is reported those involved are interviewed, the vehicles and the crash location are inspected, and the injury data is obtained from the hospitals. This information is analysed to determine how the crash occurred and which combination of man-vehicle-road factors played a role. SWOV uses the results as a basis to recommend appropriate measures.
