WebMean queue discharge headway at traffic signals: The default value for this parameter in the model is 1.8 s/veh (which is equivalent to a saturation flow of 2000 vphgpl under ideal conditions). The queue discharge headway per vehicle type is randomly assigned by the model, depending on the driver's aggressiveness factor. ... WebSep 11, 2024 · The diagram shows that headway of vehicles decreases with the queue dispersion. A stable headway can be observed after the fifth vehicle position of a queue, giving a saturation headway of 2.05 s per vehicle. Six types of continuous distribution are tested to model the discharge headway distribution.
