Factors that make public transport systems attractive : A review of travel preferences and travel mode choices

Background: Many regions worldwide are struggling to create a mode shift from private cars to more sustainable transport modes. While there are many reviews regarding travellers' preferences and travel mode choices, there is a lack of an updated review that provides a comprehensive overview of the factors that make public transport systems attractive. Aim: This review aims to fill the knowledge gap by offering insights into the factors influencing travel behaviour and the demand for public transport. It has two primary objectives: & BULL; Summarize general conclusions drawn from international literature reviews. & BULL; Present specific insights on the topic pertaining to the Nordic countries. To the best of our knowledge, this is the first review with a Nordic focus regarding public transport preferences and travel mode choices. The special focus on these countries is motivated by their relatively more ambitious policies for reducing emissions in the transport sector compared to many other countries, and their relatively high usage of public transport today. Methods: To achieve these objectives, we conducted a review of existing literature. This review encompassed international literature reviews and included an examination of results from the Nordic countries. Findings: The findings show that reliability and frequency are important factors for creating an attractive public transport supply. However, there is only limited evidence regarding the impact of improvements in these attributes on public transport demand, so this needs more research. This review highlights the importance of understanding the underlying motivations for travel mode choice and provides recommendations on areas for further investigation to understand the attractiveness of public transport supply
