Collision risk mitigating system for light rail vehicles (LRV)
Journal Title: Archives of Mechanical Technology and Materials - Year 2018, Vol 38, Issue
Abstract
This piece is dedicated to description of the development of collision risk mitigating system. Proposed concept of control system is designed to enhance safety of passengers, driver and other people in vicinity of light rail vehicles (tramways). Requirements were fulfilled thanks to application of lidar sensor and feature of vehicle positioning on the track map created based on precise measurements with the use of satellite navigation system Real Time Kinematic. Map allows to eliminate errors of system operation and to enhance resistance to unfavorable ambient conditions, i.e. temperature or fog. System calculates work braking distance for particular vehicle speed. In case of obstacle detection which is closer to vehicle than the calculated braking distance, driver is informed about collision risk with a buzzer and optical signalization. System has already been implemented and tested.
