Abstract
Traffic and transport problems do not stop at municipal boundaries. Provinces have a coordinating role in tuning categorization plans in terms of coherence and uniformity. In the regional planning process, cooperation must take place with all the relevant parties involved. This is also important to get support for measures to be taken. Coherence, uniformity and cooperation are also needed in the actual implementation of measures. In a one-day study trip, organised by the magazine Verkeerskunde and the transport bureau Goudappel Coffeng, interested persons could see and hear by themselves how the regional planning process is designed in the province of Overijssel and what this has resulted on the roads.
