In this paper, we focus on the crucial task of understanding and modeling pedestrian behavior, which is essential for numerous applications. We introduce a semantic representation of pedestrian crossing behavior. The representation is to capture the sub-events within a behavior and the spatial-temporal evolution of interactions between pedestrians and other objects involved in crossing events. We demonstrate its practical application by utilizing it to analyze pedestrian crossing behavior from road user movement data (i.e. trajectories). By constructing a knowledge graph from detailed road user dynamics data using this representation, we enable queries that address safety concerns related to pedestrian crossing behavior, aiding traffic engineers in their work on urban traffic infrastructure design.
