Brief Description of Research ProjectThe overall objective of this project is to investigate develop a quantitative method or measure for determining the need to rehabilitate rail crossings. The scope of the overall project includes investigation of sensor capabilities, development of a measurement methodology and test of technology. This project represents the next step (follow-on to phase 1 and phase 2 NURail work) towards automating the crossing inspection process, ultimately leading to the quantification and estimation of future performance of rail crossings. Proposed tasks include: 1. Finish customization of the ATTIF vehicle dynamic model developed by the University of Illinois, Chicago 2. Obtain LiDAR point cloud for 2 rail crossings 3. Calibrate ATTIF model for test vehicle (Chevy Impala) 4. Obtain field data from accelerometer for various speeds at 2 crossings 5. Validate ATTIF model for test vehicle, calculating goodness of fit 6. Write report
