Improving the accuracy of estimating the shortest path distance while reducing model training time is crucial. Existing methods for embedded shortest path distance estimation often take too long to train or sacrifice accuracy to save time. To solve these problems, an encoder-decoder framework has been designed to estimate the shortest distance in a road network by analyzing existing embedded systems-based shortest-path distance estimation methods. The core process is broken down into three parts: embedding method, sampling method, and model training. A road network vertex embedding method, RGCNdist2vec, leverages road graph convolutional networks to capture the structural information of the road network. For model training, a three-stage sampling method using graph logical partitioning is designed to select a small number of high-quality samples. Experiments conducted on four real road network data sets demonstrate that the proposed model achieves higher estimation accuracy while reducing training time by nearly four times compared to existing baseline models.
