Conducted by the Swiss Transport and Environment Association (ATE), this study seeks to measure the impact of the Walking Bus campaign in Switzerland, where the practice is known as the ‘Pédibus'1. Over 1,000 parents were surveyed in order to gain an understanding of children's mobility practices and the factors which influence their choices, the use of the Walking Bus in Western Switzerland and its impact on children's mobility, the key motivating factors for parents, and the perceived benefits. This analysis is based on two analytical components: the first examines the entire country, while the second concerns the development of the Walking Bus in Western Switzerland, the Swiss region where the concept was first adopted. The goal is to gain a clearer understanding of children's mobility, for the benefit not only of urban planning and development stakeholders, but also those involved in children's daily journeys to and from school.
