Methods and apparatus for extracting headway information from LiDAR trajectory data received from a roadside LiDAR sensor system. In an embodiment, a LiDAR data processor pre-processes raw roadside LiDAR sensor data, extracts headway data from the pre-processed raw roadside LiDAR sensor data and extracts critical headway data from the extracted headway data. In some implementations, the pre-processing may include filtering background information from the raw roadside LiDAR sensor data, clustering objects in the filtered LiDAR sensor data, and classifying the clustered objects, wherein the clustered objects represent road users. In addition, in some embodiments the LiDAR data processor may track movement of the clustered objects in real-time to extract trajectory and speed data, and then map the extracted trajectory and speed data such that the clustered objects are georeferenced.
