The Distribution of Blocks in an Uncongested Stream of Automobile Traffic

The time instants at which the cars in a stream of uncongested traffic pass a point on the roadway are distributed at random. To a pedestrian trying to cross the street or to a driver on a minor side-street, the traffic stream may be viewed as an alternating succession of periods which permit crossing and periods which do not. Probability distributions of the lengths of these periods are developed and discussed.
