Abstract

With continuous urbanization, cities are undergoing a sharp expansion within the regional space. Due to the high cost, the prediction of regional traffic flow is more difficult to extend to entire urban areas. To address this challenging problem, we present a new deep learning architecture for regional epitaxial traffic flow prediction called GACNet, which predicts traffic flow of surrounding areas based on inflow and outflow information in central area. The method is data-driven, and the spatial relationship of traffic flow is characterized by dynamically transforming traffic information into images through a two-dimensional matrix. We introduce adversarial training to improve performance of prediction and enhance the robustness. The generator mainly consists of two parts: abstract traffic feature extraction in the central region and traffic prediction in the extended region. In particular, the feature extraction part captures nonlinear spatial dependence using gated convolution, and replaces the maximum pooling operation with dynamic routing, finally aggregates multidimensional information in capsule form. The effectiveness of the method is evaluated using traffic flow datasets for two real traffic networks: Beijing and New York. Experiments on highly challenging datasets show that our method performs well for this task.
