In the period from December 2000 until June 2001 he has – by order of the Directorate General Passenger Transport (DGP; main contact: Alphons Daniëls) of the Dutch Ministry of Transport – extensively reviewed a report on fraud-resistant odometers (FEL-01-C039) written by TNO (Netherlands Organisation for Applied Scientific Research).
In that period, he has also contributed much to paving the way for the Dutch TDP (Time-Distance-Place) road pricing project of 2001, and to the birth of the MobiMiles report more in particular. Nevertheless, he was not involved in the Ministry's road pricing project at first.
However, in August 2001 he was invited by the Dutch Ministry of Transport to lecture extensively on his ideas regarding TDP road pricing. Apparently, his lecture did have quite some – additional – influence on the thinking of technical people of the Ministry's TDP road pricing team. (See e.g. Section 1.2 of this paper on EETS by Jan Vis of the Dutch MoT and also the history according to him.) A while after this lecture he became reviewer and advisor for said project and became member of the working group “System Architecture and Requirements Specification”.
In 2002 he continued working on said project as member of the so-called “Standardisation Committee Open Standard” (headed by Prof. Maarten Boasson), which was a small committee supervising certain technical aspects (including the system architecture and requirements specification) of the Dutch TDP road pricing system then being developed. Due to the outcome of the elections in May 2002, this work (and the whole TDP road pricing project) ended in November 2002.
In 2007 he reviewed the privacy aspects of four tentative road pricing approaches developed and considered by the Ministry of Transport as possible ‘intermediate’ solutions, that is, as short-term solutions that might be used as a first step towards full TDP road pricing.
In the period 2003-2005 he has been involved with giving expert advice regarding traffic pricing to the Slovenian Ministry of Transport. From March to November 2003 in cooperation with Dik van Wijk and by order of the Transport Research Centre (main contacts: Jacorien Wouters, Victor Avontuur and Jan-Willem Tierolf) of the Dutch Ministry of Transport in the context of the Partners for Roads initiative. And roughly since September 2003 in cooperation with Stefan Eisses and by direct order of the Slovenian Ministry of Transport (main contact: Dean Herenda, Under Secretary of Transport).
