Learn why trajectory-based observation matters - and how tracking movement over time reveals behavior, interactions, and safety patterns that point-based data can miss.

Explore what is visible when speed is observed through movement, not summarized at a point. Trajectory-based observation reveals how speed choices unfold across the roadway, like instant replay for traffic operations.

Understand where people actually cross the street when movement is observed over time. Trajectory-based observation reveals how distance, delay, and time pressure shape crossing choices across the roadway, turning isolated moments into repeatable patterns.
