Private transport
Since 1994, the study of private transport has used the vehicle registration register of the RDW Vehicle Technology and information Centre. Private transport is the transport required or produced by the company itself. In the National Vehicle Registration, commercial vehicles can be identified by the (grey) registration number. The vehicle is the research unit for the private transport company. For drawing the sample from the vehicle registration register, the vehicles registered as belonging to haulage companies have been removed. All other owners of commercial vehicles with a carrying capacity of ≥ 1.5 tons are also surveyed.
The private transport survey includes both the registered and non-registered private companies and those haulage companies that do not have to be licensed. These last two types of transport only have to provide data voluntarily. Research has shown that about 93% of all private transport goods, measured in weight transported, is transported with the authorisation of a certificate of registration of the SIEV.
Exempt from registration or licence obligation is, among other things, transport carried out by:
- vehicles of government organisations such as Ministries, Police, Fire Brigade, The Bank of the Netherlands, and the Red Cross;
- vehicles that deliver post as meant in the Postal Law;
- vehicles used by farmers for agricultural purposes;
- vehicles with a maximum carrying capacity of 500 kg.;
- vehicles for collecting household rubbish, or those used by municipalities for sanitation;
- vehicle up to 3,500 kg (including vehicle weight) for delivering newspapers, magazines, and printed advertising.
The sample of private transport has been stratified by three carrying capacity classes. Vehicles between 1.5 and 10 tons are sampled. Vehicles heavier than 10 tons are all included. Each week, about 1000 questionnaires are sent; for a period of 2 or 3 days, questions have to be answered about the number of kilometres travelled and the loading and unloading of the vehicles. From these reports, the loaded journeys are calculated. The loaded journey distances, together with the distances travelled between loading and unloading destinations of the goods, are calculated using a distance matrix and the kilometres driven as reported by the companies themselves. The unloaded kilometres are generated from the loaded journey course and the home base of the vehicle.
The vehicle owner is also asked if use has been made of a certificate of registration for private transport. The day results taken together provide insight in the vehicle kilometres spread over the whole year. The day results are extrapolated to produce quarterly and annual results.
The NEA publishes a number of road kilometres of goods transport that is considerably lower than the CBS number. Neither party has an acceptable explanation for this. The trends of both series are, however, more-or-less comparable, and for monitoring purposes this is the most important.
