Level crossing safety is a complicated subject, which is determined by numerous aspects including engineering factors, human errors and combination environments surrounding level crossings. This paper introduces a holistic approach in level crossing safety modelling by using Petri nets. The main aim of this paper is to study the effect of the traffic and train characteristics on safety measurement at level crossings. The result indicates that Level of Service (LOS) and the level crossing distance from the nearest intersection are the sensitive parameters in the Petri nets model.
