Resumen
This paper aims at assessing the effects on travel behaviour of a multimodal real-time information navigator for smartphone, developed within the project Optimod?Lyon and launched in May 2015. To this end, a quali-quantitative approach was adopted, administering a questionnaire and organising focus groups before and after the test of the application, involving a stratified sample of 50 people living in the metropolitan area of Lyon. The Theory of Planned Behaviour was used as the theoretical framework for the questionnaire design, investigating attitudes, subjective norms and perceived behavioural control. To evaluate the behavioural change, data were analysed using parametric and non-parametric tests, factor analysis and binary logistic regression. The positive attitude towards Optimod?Lyon lessened over time. After the test, the use of the different travel modes remained stable, showing a consistency on the most used mode, on behavioural patterns and attitudes, strongly related to habits and to the frequency of the past behaviour.
