Description of calculation of directions of travel of vehicles from counts of flows at various points on rotary junction; very useful method if junction has four approaches; it can be adapted for use on junctions with five approaches, and this is also described, but in such cases other methods are usually preferable; system is not applicable to junctions with more than five approaches unless some of these are one-way streets.
