Cities adopt them to help reach many objectives simultaneously, mainly the reduction of air pollution, congestion, and car ownership. Each mobility hub is unique, but many of them have similar characteristics that allow them to be classified. Various typologies exist. Although the mobility hub concept is flexible, the implementation of a mobility hub adapted to the needs and objectives can sometimes be complicated, as it requires many steps and may face difficulties at each step. Despite the simplicity of the mobility hub concept. They seem to be an interesting, complex, and challenging topic to investigate. As part of the Interreg Mobi-Mix project, we have taken a close look at mobility hubs. Based on bibliographic research and discussions with experts and cities, we established a state of the art that will help to better understand the concept. Without focusing on economic aspects, cities will benefit from different European experiences and a number of recommendations for a better implementation of mobility hubs.
