LiDAR technology, traditionally applied in autonomous vehicle navigation, has now expanded its footprint into roadside infrastructure. Roadside LiDAR aims to provide comprehensive traffic data, including behavior-level trajectory data for all road users. However, there exist challenges such as accurate differentiation between static and moving objects, as well as capturing data about unconnected entities, like pedestrians or wild animals. As our roads become smarter, there’s a growing need to optimize LiDAR capabilities for roadside applications.
The technology, developed at the University of Nevada, Reno, introduces advancements in LiDAR-centric innovations tailored for roadside applications, presenting a comprehensive suite of solutions to optimize traffic monitoring and vehicle navigation. Beginning with an enhancement of roadside LiDAR capabilities, it prioritizes swiftly distinguishing between moving objects and static backgrounds. The incorporation of the Fast Spatial Clustering based on a Two-dimensional Map (FSCTD) enhances data processing, optimizing the detection and tracking of varied vehicles. This approach integrates traditional distance-based tracking with statistical mapping to provide a holistic environmental representation. Additionally, the technology introduces a transformative method to convert the standard x-y-z coordinates from roadside LiDAR into universally interpretable geographic coordinates. Leveraging GIS-based platforms, especially Google Earth™, it crafts an intersection of reference points between GIS and LiDAR datasets, leading to a refined, accessible, and user-friendly data representation.
