In recent years, there has been a proliferation of research on deep learning methods for expanding graph data. The increasing demand for graph data processing has led to significant and excellent results of graph neural net¬work algorithms in multiple domains, especially in computer vision, audio processing, and urban traffic prediction, where they demonstrate remark¬able efficacy. The analysis and recognition of urban traffic topology are of great significance for urban planning and management.
Traditional methods for analyzing urban traffic topology rely on man¬ual analysis or mathematical modeling, which are inadequate to handle the complex and diverse urban traffic networks in the era of big data. This paper utilizes graph neural networks to analyze urban traffic topology, fo¬cusing on a bus route network composed of bus stations, bus lines, and various attributes of the areas where bus stations are located. We explore graph neural network-based methods for analyzing and predicting urban traffic topology. We propose a model combining graph neural networks with directed graph clustering methods, using various clustering techniques to process urban traffic topology and evaluate the performance of the pro¬posed method through experiments, comparing its applicability in different cities. By combining graph neural networks with clustering methods, we design a method for identifying and predicting urban traffic topology based on graph neural networks, aiming to improve the accuracy and effective¬ness of the model. Experimental results demonstrate that the proposed method can effectively analyze, identify, and detect urban traffic topology and performs well on relevant evaluation metrics.
This article provides an in-depth analysis of urban transportation topology using graph neural network methods In future research, we can further explore and improve from the following aspects:
1. Diversification and enrichment of data sources. Current research mainly relies on publicly available datasets, which, while providing conve¬nience for our research, often fail to fully reflect the complexity of urban transportation systems. Therefore, in future work, we can try to obtain more sources of data, including satellite remote sensing data, in vehicle GPS data, etc., in order to obtain more comprehensive and accurate urban traffic information.
2. Optimization and improvement of the model. Although this article has adopted the method based on graph neural networks to analyze the urban traffic topology structure, there are still problems such as insufficient model performance and low computational efficiency. In the future, more graph neural network architectures can be explored and optimized based on the characteristics of urban transportation to improve the performance and efficiency of the model.
3. Expansion of application scenarios. At present, the research in this article mainly focuses on the analysis of urban transportation topology, and the application scenarios of urban transportation systems are very wide, including traffic flow prediction, accident detection, path planning, etc. Therefore, future research can apply graph neural network methods to more fields of transportation system analysis and management to achieve wider application value.
4. Deepening interdisciplinary cooperation. The urban transporta¬tion system is a complex system involving multiple disciplines such as trans¬portation engineering, urban planning, and artificial intelligence. There¬fore, future research can strengthen cooperation with other disciplines and provide more comprehensive and in-depth support for the analysis and management of urban transportation systems through interdisciplinary perspectives and methods. In summary, although this article has achieved certain results in the application of graph neural network methods, there are still many areas worth further exploration and improvement. We look forward to achieving greater breakthroughs in data collection, model opti¬mization, application scenario expansion, and interdisciplinary cooperation in the future, providing more effective and accurate technical support for the analysis and management of urban transportation systems.
