Man commits movement at different targets (employment, education ...). In this case, he can use a private car, and maybe in other ways - by public transport, on foot, bicycle .... Our research shows that the probability of being involved in a road traffic accident using public transport is much lower than when using personal vehicles. Because with this it would be interesting to know the results of studies on the effect of the quality of passenger traffic (speed, density of the route network, etc.) public transport on the distribution of modes of transportation, and as a consequence, on road safety.

Article Passengers Preference and Satisfaction of Public Transport in Malaysia
In the first DRAG-1 model based on monthly time-series for the Province of Quebec, in 1964, numerous attemps were made to relate transit service to road accident frequency, severity or victims, but because the frequency of transit service is correlated with economic activity on a monthly basis, the results were not credible.
When an official version of the model was developed by the goverment road insurance board (SAAQ) in 1993-95, the only links established with about 450 monthly observations were between public transit strikes and road accidents, but even these were not statistically significant (although they seemed plausible). For this reason, the summary of this DRAG-2 model (Fournier & Simard, Ch. 2, 2000; enclosed) does not talk about this small impact although the strike variable is enclosed among the regressors, as you will note on p. 4 of the detailed listing of regression results (enclosed: ch.15, 2000).
Both chapter 2 and chapter 15 come from the book summarizing about 7 national or regional road accident models using the common DRAG-type structure:
Gaudry, M. and S. Lassarre (eds), Structural Road Accident Models: The International DRAG Family, Pergamon, Elsevier Science, Oxford,2000.
As ch. 15 contains the detailed regression results for all 7 national or regional models, you will also note that none of the other models contain transit service variables to explain road accidents. Good luck.
