A model for estimating the capacity and the delay at signalized intersections is presented. With the modeling of a signalized intersection as a queuing system, the capacity can be estimated by the measuring of the cycle overflow probability at stop line detectors. On the basis of a given queuing model, the stochastic characteristics, that is, the randomness of the queuing system at a signalized intersection, can be estimated as well. Then, the delays and the queuing lengths can be obtained with the estimated parameters. The results of the presented model are underlined by a comprehensive sensitivity analysis. Furthermore, a Vissim simulation study was conducted to demonstrate the capability of the model, and the model was tested on the basis of field measurement data.
