Grade crossing, high-profile grade crossing, humped grade crossing, LiDAR, automated, DOTX 218

FRA’s Office of Research, Development and Technology (RD&T) has developed and deployed a LiDAR-based system on its DOTX 218 research vehicle (see Figure 1) that creates accurate, high-density point clouds of track and surrounding area in and around grade crossings at survey speeds of up to 55 mph. This research results paper presents highlights of the FRA’s development program and provides an overview of initial deployment and use of the resulting technology.
