Samenvatting
In april 1978 a traffic-circulation-plan was introduced for the inner-city of Delft, the "Accessibility Plan". Pre- and post-surveys were done to check the effects of the traffic measures. It may be concluded from the total of inquiries that the primary aim of the Accessibility Plan (a better environment in the "old city" by adapted traffic-circulation) has been reached for the greater part, without damaging the retail-trade in general.
