Abstract: Projektet förväntas ge inspiration till nya forskningsprojekt som berör planering, teknikintroduktion och beteenden hos transportkonsumenter. Resultaten sammanfattas i en idépromemoria.Abstract: The aim of the project is to bring out the main barriers to why earlier efforts towards a sustainable transport system have not developed further towards sustainability.
