How will the speed of cyclists be controlled, as it is highly likely that the speed of the cyclists will rise as they feel they are in a controlled and safe environment, which of course would be detrimental to pedestrians? This in turn may increase the anti social attitude between the two groups?

Whilst it would be difficult to predict the future popularity of the scheme for people on cycles and people on foot, the design team hopes that the level of conflict between these users is sufficiently high to confirm the scheme as a success. Currently the Broadway is an uninviting car-dominated environment with very little cycling activity and poor pedestrian provision and retail offer – the potential for conflict is low. The aspiration of the scheme is to reinstate the Broadway as a busy local High Street on behalf of RBK.
