In this master thesis we confirmed the hypothesis that increased road capacity due to shorter travel times results in increased number of kilometers travelled by car. It deals with a theoretical basis of induced travel as well as with a review of numerous case studies in the international literature, evaluating the volume of induced travel. We have concluded that those studies that attributed an important impact to induced travel are numerous, more complex and they are of more recent date than those studies who didn't prove the considerable importance of induced travel. We have carried out a survey on travel behaviour in Slovenia using stated preference method. We have asked the respondents to predict their behaviour in hypothetical case of road capacity improvement reducing the travel times for different types of travel: work/school, shopping, leisure activities and escort of children to kindergarten (school). The most often chosen changes of travel behaviour were: taking the longer road, changing the location of residence, work, shopping and leisure activities and increasing the frequency of leisure activities, taking the car instead of other means of transport and reducing car occupancy when travelling to leisure acitivies. The correlation between different variables were calculated. Four different groups of people were identified based on number of different travel behaviour changes chosen. It is more likely that those who have a strong tendency to change their behaviour are women, less educated, younger and inactive respondents. Research has confirmed that in hypothetical case travel behaviour changes would induce traffic in Slovenia and at the same time refute the hypothesis that induced travel and dissapearing traffic are unknown phenomena in Slovenia. The value of research stands in improved understanding of different types of induced travel.
