Abstract

Modern AI and ML traffic prediction models provide accuracy, yet lack interpret-ability. Our approach designs a local neighborhood of segments and time-periods to construct a prediction data set that contain explicit dynamics across properties measured in the spatial temporal frame. The approach performs similarly to a popular TGCN ML model while providing opportunity to understand the relationship between predictor and predictand across the graph structure to which it is applied.
