Abstract

Accurate prediction of freeway travel time is quite significant for traffic management and travelers' trip decisions. A model of stacked automatic encoders for freeway travel time prediction is proposed. First, obtain the hourly average travel time by processing freeway toll data. Considering data quantity and travel time scheduling, a travel time prediction model based on stacked automatic encoders is established then. The automatic encoder is trained with unsupervised learning step by step by using historical travel time data, adjust the parameters of prediction layer with gradient descent method. Ultimately the one-hour travel time is predicted using the past three-hours' average travel time. Compared to the traditional BP neural network prediction model, the Root Mean Square Error of this method drops by 13.6% ,verifying the validity of the model.
