NEW DUTCH CAPACITY STANDARDS FOR FREEWAY WEAVING SECTIONS BASED ON MICRO SIMULATION

Traffic engineers in The Netherlands are not satisfied with the present guidelines on freeway capacity. For this reason the Dutch Ministry for Transportation, Housing and Water Management gave order to make a manual on freeway capacity. One of the chapters in this manual is on weaving sections. This paper describes the research on weaving capacity needed to make the first version of this chapter. The research consisted of a literature search on weaving capacity worldwide and a simulation study on the capacity of Type A weaving sections using the micro simulation model FOSIM. In the simulations weaving section length, weaving flow rate and truck percentage were varied. The results are presented in capacity diagrams for specific weaving section configurations. Capacity results are combined in diagrams for all configurations together. Estimated pcu values for trucks are not the same for all configurations considered. Vermijs 2 1.
