This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

If you are using GIS software can you let us know which product(s) so that we can phrase a suitable answer, please? Most GIS software will have their dynamic segmentation (sometimes known as linear referencing or chainage) capabilities documented. –  PolyGeo May 17 '13 at 10:18

Isn't it possible without using other module. I need to use it in Arc Map 10. –  Ja Geo May 17 '13 at 14:28

If you have not done so yet read up on route hatching. Then you should be able to author a layer file with appropriate route hatching that you can use to add/update a layer using ArcPy.
