I don't know the algorithm, but among the many definitions, dynamic
segmentation allows analysis and mapping of linear features based on
their positions along a route. Another definition says that it is "the
process of computing the locations of events on linear features at run
time based on event tables for which distance measures are available."
Used in linear reference systems (LRS), typically for roads and
transportation networks analysis.
