Establish the Queue Length Function Model
Abstract:
A queue length function mapping model is built through the neural network, and can be optimized based on the white noise principle. Thus, a nonlinear mapping, which the input and output nodes are considered as independent variable and the dependent variable respectively, is obtained. After training the learning samples, which can be got from counting the data of the accident duration, traffic upstream, the passed coefficient, and the vehicles queue length, we can acquired the weights and thresholds, which are used to represent the mapping between the nodes. Also, through the optimization based on the white noise principle, the impact caused by the error can be reduced and a more accurate model is obtained as a predicting measuring tool of the queue length.
