Cities that invest in the development of active and collective transportation services ensure more than their inhabitants’ mobility: they reinforce local economic and social activities by promoting local travel, improving accessibility to and networking among local resources, helping to reduce pollution of public space, and fostering the development of pedestrian neighbourhoods. In most cases, the new services are being developed by community members who join forces to create innovative responses to needs that are not being met by existing services. Partnering with local governments ensures the realisation and improves the organisation of many of these initiatives and helps to ensure their sustainability.
