Abstract: The present invention relates to a method and a device for predicting road network travel speed by using a deep neural network. The travel speed in a given road segment is affected by the current and past travel speed of adjacent road sections, and the influence is further extended to the rest of a traffic network. Therefore, a successful prediction model must consider not only the influence of the adjacent road sections but also the influence of distant road sections. Based on the principle, a deep neural network structure for receiving not only time dependence but also spatial correlation across the city is proposed for the topology of an actual traffic network, and an extended model of the proposed prediction model is proposed in terms of traffic state transition and propagation. The present invention was carried out by using a large data set collected for more than 10 months, and successfully predicted the travel speed of 170 road sections in Gangnam, Seoul. The method comprises the following steps of: forming a connection between layers or neurons, and inputting a travel speed data set to an input layer of the deep neural network; obtaining an estimate of a future travel speed for a road network, and measuring an error by comparing the estimated travel speed with an actual observed value by using a loss function; and modifying a learning parameter of the deep neural network according to the error, and improving the prediction accuracy of the travel speed of the road network.
