HIGHWAY DELAYS RESULTING FROM FLOW-STOPPING INCIDENTS

THE OCCURRENCE OF AN INTERRUPTION TO THE FLOW OF TRAFFIC ON MODERN FREEWAYS CAN GIVE RISE TO A TIME-CONSUMING TRAFFIC JAM. FOR EXAMPLE, WHEN AN ACCIDENT OCCURS, MANY OTHER VEHICLES MAY BE QUICKLY HALTED, AND REMAIN STOPPED UNTIL THE IMPEDIMENT IS CLEARED AWAY. IN ADDITION, THE FLOW OF TRAFFIC MAY BE SLOWED CONSIDERABLY EVEN AFTER THE ORIGINAL STOPPAGE IS REMOVED OWING TO THE EXISTENCE OF A QUEUE. THIS PAPER SUGGESTS AND EXAMINES, IN SOME DETAIL, SEVERAL MODELS FOR THIS SITUATION, WITH THE AIM OF ESTIMATING THE CONSEQUENCE OF A TEMPORARY FLOW RESTRICTION. THE MEASURES OF EFFECTIVENESS CONSIDERED ARE THE TOTAL NUMBER OF VEHICLES INVOLVED IN THE TRAFFIC JAM AND THE TOTAL VEHICLE-HOURS WAITED WHILE THE JAM DISSIPATES. BOTH STOCHASTIC AND DETERMINISTIC MODELS ARE EXAMINED AND COMPARED. /BPR/
