Abstract

Show how the space mean speed of a traffic stream and the flow may be estimated by an observer travelling with, and against the traffic stream. Prove any formulae which are used. The following observations were taken by an observer travelling with and against the traffic stream; calculate the mean traffic stream speed and also the flow.
