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.
Issues and techniques for creating homogeneous sections

2003 - Cumulative Deviation Sectioning - Software
 277.29 KB

Software which uses the principles of cumulative deviations (CUSUM) for creating homogeneous sections for analysis with programs such as HDM or any other PMS. Manual can be downloaded elsewhere.

2002 - NZ - Sectioning Improvement
 490.46 KB

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.


Chris in the NCT Race 

Chris has an adventurous spirit which generally involves cycling, running, or just being out there having a good time. Read his 'Race Reports' below. This is a link to his SPOT GPS tracker. If you are interested in his 'geeky' sport technical blog it is at www.tri-duffer.com. He also has stories of his life as 'An Overtravelled Engineer Working for the World Bank' at World Bank Traveller.

Chris and Lis

We are Lis Pedersen and Chris Bennett. We’ve been married over 30 years and each found our way to New Zealand in the early 1980s from Denmark and Canada respectively. Golden Bay has been our happy place for almost 20 years and we are now based in Pohara just above the beach, with our two cats Coco and Max.
