The ten kilometres between Rotterdam and Delft have now been transformed in part to a direct and fast bicycle route with a largely separate bike path and few intersections. The route has been asphalted partly in red, has no traffic lights at all and the cyclist always has the right of way.
According to a interim evaluation measures like levelling asphalt, adding lighting, separating cyclists from other traffic and removing barriers lead to a measurable increase in the number of cyclists.
Of the cyclists interviewed on five congestion-free routes, 28 per cent were new cyclists and 72 per cent were existing cyclists. Of the new additions, 4 per cent used to travel by car. Of the existing cyclists 1 per cent cycled more often, instead of travelling by car. On the routes Utrecht-Breukelen and Rotterdam-Delft a very distinct increase (more than double) of the number of cyclists has occurred after the upgrading.
In addition the evaluation demonstrates that the Fiets Filevrij campaign has a major directing part in upgrading bicycle routes. The combination of stimulation, direction and communication makes it easier to obtain funds and the routes are constructed quickly.
