Samenvatting
The question of capacity is of great importance for the design of busy roads. The German guideline for grade-separated junctions has deficiencies in describing traffic quality and capacity. During this research project, a technical procedure has been developed for dimensioning on-ramps on grade-separated junctions. The procedure is based on empirical investigations. The calibration results are expressed in the form of diagrams. They offer a practical procedure which enables the user to judge the traffic quality and quantity at on-ramp sections of motorways. This procedure is mainly valid for urban motorways. (A)
