Abstract: Efficient learning of representation of urban road network information is an important project for embedding various deep learning models to intelligently solve downstream traffic tasks. However, the existing learning framework are difficult to effectively couple the topology information of the urban road network and the transfer mode information carried, and cannot accurately match the characteristic requirements of downstream traffic tasks. In this reason, this paper develops a multi-view roaming segment representation vector learning framework, which takes the vehicle movement pattern as the core, integrates the topology structure for heterogeneous walk, and realizes the complete and efficient information embedding of large-scale road network. In the experimental part, taking Shenzhen as the case area, the effectiveness and advanced nature of the method in this paper are verified through the full urban road network and actual vehicle travel data.

Key words: Trans2Vec, urban road network, vehicle movement patterns, representation learning
