Abstract: This note examines a general form of link travel time functions considered in the dynamic traffic assignment literature and shows that it only makes some physical sense in the special case where each function denotes either a link with no spatial dimension containing a point queue, or a link with constant travel time and no queueing. Roadway segments exhibiting both phenomena must be represented by two links in series.
