In This project investigates the trajectories of cars after a collision with a locomotive at a level crossing in order to find out how far the level crossing coating should be extended so that the car can move off the coating to the sidewalk as soon as possible. The first chapter analyzes the level crossing coating structures, examines the research works, which examines the collisions of trains and cars at the railway crossing, the accident level of railway crossings in Lithuania and the European Union. The second chapter describes the collision investigation methodology, collision model and collision investigation using specialized software „PC – Crash 8.0“ detailed analysis of collisions. Three brands of the most popular car manufacturers in Lithuania – „Opel“, „BMW“ and „Volkswagen“ – are selected for the research. The selected locomotive model is the „TEP70 BS“. The study is performed at different locomotive and car speeds. Three different speeds are selected for the locomotive – 50 km/h, 60 km/h and 70 km/h. Four different speeds are selected for the cars – 30 km/h, 50 km/h, 70 km/h and 90 km/h. In the third chapter, a collision study is performed to determine the worst case collision. The worst case study is performed at a speed of 70 km/h for the locomotive and 30 km/h for the vehicle. In the fourth chapter, according to the obtained results, proposals for the reconstruction of crossings are presented, and an economic evaluation is performed. |
