dynamic traffic assignment

Dynamic traffic assignment (DTA) is a simulation-driven approach to transportation planning that models individual vehicles, lane changes, signal interactions, and multimodal effects. Unlike static traffic studies, DTA provides continuous, operational-grade simulation for citywide planning. Edmonton's deployment of OpenPaths DYNAMEQ and EMME for dynamic traffic assignment represents one of the most ambitious municipal-scale DTA efforts in Canada, enabling faster, more defensible capital investments, signal timing strategies, and corridor-level operational decisions.
