In several European countries programmes have been set up to manage and restrain mobility/transport use. For commuter traffic, the emphasis has been on reducing use of Single- Occupation Vehicles (SOV) and TDM policies were set up to stimulate alternatives such as cycling, carpooling and the use of public transport.
However, in promoting alternative modes of transport, a new problem arises - the Õcar that stays at homeÕ. So far, it is not clear what happens to a car left at home by its first user. Does it really stay at home? Or is it used by other members of the household for additional journeys, or for journeys that would otherwise have been made by other means? Is the car being used more or less than before and at what time of day? What is the actual re-use percentage?
This paper describes the results of a study on the re-use of cars which are left home by the first user (e.g. the first user does not commute anymore by car as a SOV, but uses public transport, goes by bike or carpools). The project consists of several phases. During the first phase existing data are analyzed. In the second phase new data are collected to verify and extend the results of the preceding phase. And, finally, in the last phase data are collected on re-use, using a one week trip diary in a selected sample to investigate re-use within households in more detail. The present paper mainly deals with the results of the analyses of existing data.
Section 2 gives an overview of expected effects and relevant population segments. In section 3 the analyses of the travel survey data is given. Section 4 focuses on the background characteristics of the households with a car that stays at home. Section 5 describes the set up of the survey for potential households with a car that stays at home and is being re-used. And finally, in section 6 some conclusions are drawn, which will be used as guidelines for the following phase of the project.
