Удосконалення методу оцінювання показників аварійності за участю пішоходів на залізничних пішохідних переходах

This study assesses a method for estimating the final accident rate at railroad pedestrian crossings depending on the intensity of train and pedestrian traffic and taking into account the geometric and planning features of the pedestrian crossing and information support. An improved method for estimating the accident rate at railroad pedestrian crossings has been proposed, taking into account the set of factors influencing the safety of pedestrian traffic when crossing railroad tracks. The method is based on determining the final accident rate, which integrates eight key factors that make it possible to define the level of danger of the crossing according to established standards. The method takes into account the intensity of train and pedestrian traffic, the information and technical equipment of the railroad pedestrian crossing, as well as the planning and geometric parameters of the crossing. It also considers the speed of pedestrians depending on their physiological and age characteristics. Multivariate modeling of the influence of train and pedestrian traffic intensity on the final accident rate has been carried out; the effectiveness of using information systems for warning pedestrians about the approach of a train in the pedestrian traffic safety system was also assessed. It was established that the average value of the reduction in the accident rate at railroad pedestrian crossings within the existing railroad crossings depends on the intensity of train and pedestrian traffic. When using an additional information system for warning pedestrians about train traffic, taking into account the influence of train traffic intensity, it is up to 22.1, and taking into account the influence of pedestrian traffic intensity with a constant number of train pairs, it is 27.74. The use of the information system for warning pedestrians about train traffic ensures a reduction in the accident rate of up to 30%. This increases the safety of pedestrian traffic when crossing railroad tracks
