Abstract

Improving the vitality of self-organized recreational path network is an important goal of urban renewal planning. Due to the discontinuity and the existence of dead end roads in the recreational path network in old towns, the comfort of residents’ recreational activities is restricted. The self-organization of recreational path network means that the top-down planning and design mode is difficult to match the needs of citizens. How to deduce the spatial vitality of recreation planning in a bottom-up mode and then identify potential land plots is an important issue to improve the quality of urban recreational path network. By taking the old town in Guangzhou as an example, this paper constructs the indicators of break degree and spatial vibrancy based on the complex network theory. Then, by using GPS trajectory data to identify the breaks in the existing recreational path network, the identification of discontinuous breaks based on citizen recreation behavior and the activation effect of urban renewal projects are quantitatively discussed, and the potential impacts brought by the implementation of renewal projects are simulated. The discontinuity analysis shows that the break degree of the recreational path network in the old town in Guangzhou is generally low, and the connection degree is good, but there are still some obvious breaks due to the street location and historical problems. Moreover, the results of spatial vibrancy deduction show that urban renewal projects have a positive impact on the self-organized recreational path network, and that the implementation plan and schedule of urban recreation quality improvement projects can be determined according to the deduction analysis results. This study makes a beneficial exploration of urban self-organizing characteristics from the perspectives of planning and transportation, and makes up for the deficiency of top-down planning in considering urban self-organized recreational path network.
