Abstract: The current road network matching methods are highly subjective in determining the weighted relations and matching threshold and prone to matching errors. Therefore, a road network matching method combining graph convolutional neural network is proposed. First, four similarity measure factors of length, direction, distance and topology are selected as the feature factors of the road network matching model. Then the roads to be matched are transformed into a dual graph with roads as nodes and road connection relations as edges, thus to match road network through node classification. Finally, the road network matching is realized by building a graph convolutional neural network. The results show that the matching accuracy, recall rate, and F-value of this method are greatly improved compared with the traditional methods, and it can effectively solve the road network matching problem.
