摘要: Abstract In the context of dynamic traffic assignment (DTA), network loading map represents a flow model. Assuming that an iterative DTA microsimulator is given, this article discusses several techniques for linearization map. The practical work problem calibrating travel demand from counts: simulated mapped on counts through map, and hence provides directional information adjustment such real-world can be reproduced to reasonable degree. proposed rely recursive regressions are fitted model during iterations microsimulator. It demonstrated approach performs substantially better than usually deployed proportional in it even functions congested conditions.
