In this study it has been investigated how the accident risk changes if the protection device in a railway level crossing is rebuilt or the crossing is erased as well as how the expected socioeconomic accident costs change if different types of crossings are erased. VTI’s existing data on railway level crossings and accidents have been supplemented with information from a few more years and is now including year 2000 to 2015. Estimates have been carried out using logistic regression analysis with the outcome of accident or not as dependent variable. As explaining variables, the number of train passages, three road types (as a proxy for road traffic flow) and four different types of protection devices have been used. Analyses have been carried out both for accidents with motor vehicles and for vulnerable road users. As in previous studies, this study shows that the probability of a railway level crossing accident is lower for crossings with barriers than for those without barriers, that the probability increases the more trains passing and that the probability is greater the greater the road (and thus more vehicles) crossing the railway. However, the overall probability of a railway level crossing accident is very small, and there are some uncertainties in the data, which are discussed in  the paper.
