Abstract:
According to the reality of vehicles transiting through an intersection, this paper establish the queuing model with moving the head and the tail, analyzes queuing length and delay with vehicles once and twice queuing respectively, and discusses detection of parameters of the model. The model represents queuing with the head and the tail moving up individually, and depicts their speeds of movement by stop ratio and start ratio at time segment. Both queuing length and delay of vehicles are related to the length of time segment, stop ratio, start ratio. The shorter the time segment is, the preciser the calculating results are. Convenient and feasible detection of the stop ratio and start ratio is processing of trafficflow video images, the key step is to judge the places of head and the tail several times within a time segment. The model takes shorter time segment as unit, so it can accurately describe vehicles queuing and dispersing at intersection, and the calculation of delay is simple and accurate. 1 tab, 2 figs, 13 refs.
