The development of linear referencing systems (LRS) continues to be a primary effort at Department of Transportations around the world, and the FGDC is developing a NSDI Framework Transportation Identification Standard model for routes.A LRS CD containing research papers is available from the US Bureau of Transportation Statistics and standards for LRS functional requirements are emerging. Dynamic Segmentation (dynseg), is a classic GIS tool for analysis of roads, pipelines and railroads used in transportation and utility network applications.The dynamic segmentation process generates point or linear geometry for database record events referenced by their position along a linear feature.Using dynseg, information originally stored in a tabular report can be visualized on a map and displayed, queried and analyzed in a GIS.
