As evident when reviewing past and current research projects supported by the U.S. Department of Transportation (DOT), mobile light detection and ranging (LIDAR) technology offers a significant opportunity to increase transportation safety and efficiency. Unfortunately, these projects typically rely on expensive commercial hardware that prevents widespread usage and potentially mitigates LIDAR’s overall benefits. Previous efforts within the PI’s laboratory resulted in the construction of an inexpensive LIDAR system ($300) that was able to capture up to 700k data points for a respectively accurate point cloud; hence, setting the stage for extensive implementation. However, data collection took too long for effective usage. As a result, this project will build on this past research by increasing the sampling and data collection rate while enhancing connectivity and improving the post-processing of the point cloud information. Dissimilar places on campus will be captured (e.g., intersections and parking lots) using the system to understand how well it can identify street signs, potholes, pedestrians, etc. Overall, this will ensure that a low-cost and mobile LIDAR system will be suited for transportation-based safety outcomes. |
