Damage detection of railway tracks based on vibration measurements by moving laser sensors

BackgroundRailway transportation plays a key role in mass transportation of products and passengers. One of the biggest problems that endanger safety and operation of railways is the fractural cracks of the railway tracks. Even though ultrasonic measurement techniques have been extensively used for detection of such defects, these methods may show inefficiencies....

Truck-mounted pavement deflection monitoring system using high-precision laser scanners and inertial sensors

A new easy to use universal pavement deflection monitoring system to monitor road healthThe deflection of pavement when a moving vehicle passes over it is an important measure of its condition. Since pavement damage is initially not visible on a road’s surface, pavement deflection should be measured as often as possible for the efficient maintenance...
