WG3-Vehicle-based survey

On the European average more than 95 % of all passenger cars and half of all light commercial vehicles are permanently available to private households. These vehicles can be either company cars or privately owned.

The profiles of vehicle use can be specified through average annual driven mileage per vehicle and for the fleet as a whole total, the purpose of travel as to the trip destination, the infrastructure use could be shared among urban, inter-urban or motorway road use, and fuel consumption could be measured together with e.g. data on CO2 emissions. Hence data collected on vehicles are also of great interest for a better knowledge of European mobility trends.

Other relevant issues are the use characteristics of vehicles, which are relevant e.g. for the development of electric no emission vehicles with limited battery capacity (maximum distances covered with which vehicles, time is remaining for recharging at which places). Up to now only one harmonized major data base exists at the European level: the Continuing Survey of heavy goods vehicles. Based on this good practice, this working Group will establish the state of the art in Europe of different vehicle data sources, such as:

  • Households car ownership and use;
  • Light commercial vehicles (LCVs)
  • Heavy goods vehicles (HGVs)
  • Study of business decision making in the container transport industry, as part of the development of a <qtlend></qtlend>new strategic freight model scheme and
  • Methods of quantitative firm survey, enabling the modeling of road occupancy for urban freight transport.

There are some similarities between households car use and freight vehicle based surveys like the question of loading factor which could be also understood as the occupancy rate for household survey. Prospective methods, Stated Preferences and Stated Responses have been developed both for passengers and for freight and the Action will involve research teams in these fields. There is also a common interest in methodological issues such as the optimising of sample schemes and the treatment and correction of non-sampling errors, such as non-response.
In addition several groups are actively involved in promoting new technologies for tracking (for vehicles, travelers or shipments), web-based methods for panel surveys and in the archiving and use of ITS data sources for assessment and monitoring of policy impacts. Experience in the dissemination of information via GIS systems, websites and on-line databases is increasing.
