OBIS will advance the role and the opportunities of bike sharing as a valuable instrument to foster clean and energy efficient sustainable modes of mobility in urban areas. It improves environmental performance, enhancing the quality of public transport, supports health and the overall quality of life. Due to the broad commitment of authorities to new green strategies, bike sharing is recognised as attractive to further cycling in urban areas in general. With respect to different countries, OBIS will identify good practices, success factors, limits and market potentials by analyses, demonstrations and optimised strategies. Key findings and recommendations will be published in a comprehensive manual. This handbook will support the adoption of bike sharing all over Europe and guide the relevant actors implementing efficient bike sharing schemes. It will furthermore be an essential input for adjustments in mobility strategies and frameworks.
