Paper on how to generate homogeneous sections from road data
Paper by Fridtjof Thomas. An algorithm is suggested that combines a recently developed Bayesian identification of transitions between two homogeneous road sections with a heuristic approach that uses this technique iteratively to find multiple homogeneous sections in arbitrary long measurement series. The approach is demonstrated with narrowly spaced measurement series of the international roughness index as well as rutting. The algorithm executes sufficiently fast to make the partition of an entire road network feasible.

Report on how to section road data for the purposes of pavement management.
Report describing the application of cumulative deviation principles to create homogeneous sections. Shows how critical it is to create analysis sections using a sensible and robust method.
This report focuses on the FWDCHECK program. The report is provided in three separate volumes: Technical Documentation, User’s Guide, and Program Listing. The technical documentation gives a detailed description of the program including the analyses and algorithms used. A detailed description of the program usage is provided in the User’s Guide. Finally, a complete printout of the computer source code is included in the third volume, Program Listing.
