The bicycle was once the number one means of transportation until it was pushed to the brink of insignificance by the car. Now the bicycle is back and has more political weight than it has been for a long time.
Allocating dedicated road space to slow modes is considered an effective way toward a radical modal shift. By exploiting traffic flow theoretical knowledge, convenient models can be developed to help evaluate the influence of such a large-scale transformation on network traffic performance. Novel strategies for bi-modal urban traffic management can also be proposed to solve congestion.
Many aspects contribute to the further development of the technologies, but no single game changer could be identified. Developments are expected in automation; revolutionary changes are perceived as unlikely.
