This project applies commercial remote sensing and spatial information (CRS&SI) technologies to the public transportation focus area of the Research and Innovative Technology (RITA CRS&SI) program. It integrates Ground Penetrating Radar (GPR), laser, Geographic Information Sysems (GIS), and Gllobal Posiitioning Systems (GPS), to automatically collect and georeference surface and/or subsurface data for rail, concrete ties, fastening systems, and ballast. A WebGIS-based decision support system will be developed to help rail transit employees with no GPR and laser background to utilize the collected data. |
