THE DISTRIBUTION OF BLOCKS IN AN UNCONGESTED STREAM OF AUTOMOBILE TRAFFIC

CARS IN A STREAM OF INCONGESTED TRAFFIC WHICH PASS A POINT ON THE ROADWAY ARE ASSUMED TO ARRIVE RANDOMLY. A PEDESTRIAN OR GROUP OF PEDESTRIANS ARRIVING RANDOMLY AT THE CROSSING AND TRYING TO CROSS THE STREET OR A DRIVER ARRIVING AT THE STOP LINE ON A MINOR SIDE-STREET AND REQUIRING A GAP EQUAL TO OR GREATER THAN A FIXED VALUE BEFORE CROSSING, MAY VIEW THE TRAFFIC STREAM AS AN ALTERNATING SUCCESSION OF PERIODS WHICH DO MOT PERMIT CROSSING (ANTIBLOCKS) AND PERIODS WHICH DO NOT PERMIT CROSSING (BLOCKS). ARRIVALS IN THE TWO STREAMS ARE ASSUMED TO BE INDEPENDENT. PROBABILITY DISTRIBUTIONS OF THE DURATION OF BLOCKS AND ANTIBLOCKS ARE DEVELOPED AND DISCUSSED. THE DISTRIBUTION OF GAPS AND ANTIBLOCKS ARE SHOWN TO BE IDENTICAL. THE CLOSE RELATIONSHIP BETWEEN THE DISTRIBUTION OF BLOCK DURATIONS AND DELAYS IS SHOWN. /AUTHOR/
