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.
The results show that the spatial pattern of accessibility is characterized by ‘core-peripheral’ configuration, the center has been the core region, and the transportation systems in Hankou, Hanyang and Wuchang were self-contained. As a result of history, economic and natural environment factors, the correlation between comprehensive accessibility and economic development is obvious in different regions, especially in Hanyang, the correlation is the most significant. Along the route of intercity travel unit, its accessibility enhancement, on this basis, the paper further verifies the improvement of intercity railway on urban internal traffic condition, so as to provide reference for traffic planning and urban construction.
