In this work, we contribute an EM algorithm for estimation of corner points
and linear crossing segments for both marked and unmarked pedestrian crosswalks
using the detections of pedestrians from processed LiDAR point clouds or camera
images. We demonstrate the algorithmic performance by analyzing three
real-world datasets containing multiple periods of data collection for
four-corner and two-corner intersections with marked and unmarked crosswalks.
Additionally, we include a Python video tool to visualize the crossing
parameter estimation, pedestrian trajectories, and phase …
