An Arch-Bridge Topology-Based Expressway Network Structure and Automatic Generation

The rapid generation and automatic updating of road network topology information have immense practical significance application value for intelligent expressways. Therefore, this work proposes a novel arch-bridge based on an electronic toll collection (ETC) system to redefine the structure expressway network. On basis, discrete ETC data generate corresponding trajectories according structure, initial candidate set is generated. Furthermore, characteristics abnormal topologies, such as loop, reverse, missing, opposite are deeply explored analyzed, targeted constraint conditions designed optimize set. Finally, experiments evaluations conducted transaction collected from in certain province China. experimental results show that proposed method has significant terms evaluation metrics efficiency. Specifically, recall, precision, F1 0.982, 0.966, 0.974, respectively. Additionally, it takes less than 2 ms average one topology. can efficiently accurately entire
