Safety Information System Unmanned Railway Level Crossings

It has been evaluated that level crossing of rail and roads pose potentially highly dangerous for drivers and road users in road and railway transportation system. Due to theever increasing number of vehicles daily, it was concluded that using automated techniques at level crossing can be useful for traffic and road safety transportation. Levelcrossing protection is the consequence of having level crossings on a railway line. Generally, the railway level crossing requirements is determined by the type of technologyused in order to provide a fail-safe system. The main aim of this paper is to develop an automated level crossing system that could prevent or reduction Accident between trains and road users (vehicles drivers). From the railway level crossing point of view, the requirement to be met by such protections is quite simple: it has to stop all road users before passing of a train. Special attention is paid on wheel sensor which is used to detect the train accurately; direction and speed of the train are monitored in the process. Two wheel sensor has been used to locate before (Strike-in point) and also after (strikeout point) the level crossing. On the other hand, the proposed system comprises of other warning devices such as automatic barrier, LED flashing lights and the Alarm device. Intermediate System for Incandescent Signal Locations is used as the controller to execute all the signals and programs. Barrier closing time will be optimized based on the type of train and their speed. Implementation of new technology will significantly improve safety at a level crossing without building the capacity of road infrastructure. In this work, the application potential technique to secure railroad crossings is explained in details. By applying the train detection system in railroad transportation, it is increasing control of the level crossing.
