It is very difficult, at this early stage in the evolution of CNFE, to say with any certainty that modal shift percentages can and will be achieved. It is certainly a worthwhile objective to ensure that modal share targets that are set for the whole of Cambridge are met on the site, and there is room for optimism that this can be achieved at CNFE. This will however be an exacting target, and Turnstone do not consider that it would yet be appropriate to seek to go beyond the target of 24% set for the City as a whole, therefore making the development "exemplar" in terms of modal shift. It is furthermore important to take into account that the ambitious modal share targets will only be achieved if the station "hub" is properly defined, and if appropriate space is allowed for it to flourish. In other words, there needs to be significant public realm provision, cycle and car parking and other infrastructure to maximise its use and to ensure that it is a powerful tool in delivering ambitious modal share targets.
