Samenvatting
The purpose of this research has been to develop a volume-warrant for installing 2-way stop signs at urban intersections. The volume warrant has been based on the percentage of side-street cars that meet interference from traffic on the main street. In applying the warriant to a specific intersection, only 3 quantities need to be measurePU: 1. the mainstreet volume, 2. the sidestreet volume, 3. the quantity called the critical lag, which is a constant for each particular intersection but varies form one intersection to another. In particular, a start has been made toward atheoretical explanation of the interaction between 2 intersecting streams of traffic, when both are distributed at random.
