QUEUE PROBABILITY ESTIMATES AS CONSTRAINTS TO INTERSECTION CONTROL STRATEGIES
This paper deals with the estimation of the probability of long queues on approach lanes of signalized intersections. Where the consequences of queues reaching sensitive areas are severe, both off- and on-line intersection control strategies should include an evaluation of the associated risk. Such instances include queues exceeding the length of a turning bay for left turns and blocking a through lane, or queues stretching across an upstream intersection. If the risk is unacceptably high, the cycle time, green intervals, phase structure or their sequence should be modified. This paper summarized international practices of queue determination and explains the method suggested in Canada for the estimation of the probability of a queue exceeding a given distance. The technique applies arrival flows to determine a Poisson-based dependent probability measure.
