The multi-modal public transport network has been a new trend in modern intra-urban transport. This study aims to comprehensively analyze the three types of accessibility, which are analyzed based on the urban road network, the metro network, and intercity railways in Wuhan.
The shortest-path model and average accessibility method were applied for this purpose. We describe the comprehensive accessibility and spatial difference in Wuhan, and evaluate the spatial patterns of accessibility in different transport network models. In particular, analysis of accessibility changes before and after intercity railway construction, and identify which areas are likely to improve from accessibility and traffic conditions. Furthermore, the correlation is evaluated by considering comprehensive accessibility population and regional gross domestic product to investigate the influence of urban internal traffic.
