Evaluation and Optimized Strategies of Walkability in Historic District Based on Data Augmentation

As cities continue to regenerate and develop, the concept of sustainable development has gradually become one of the main themes in the process. People have also begun to place higher demands on the walkability of historic and cultural districts. Relevant research has also evolved from subjective and emotional evaluations to objective and rational quantitative analyses. Nowadays, with the support of information technology in development, various refined quantitative research tools and relevant urban evaluation data have created a fundamental analysis platform to quantitatively evaluate the walkability of historic and cultural streets. In this context, this paper attempts to sort out and develop a quantitative evaluation system for historic and cultural districts based on the concept of data augmented design, and thus develops corresponding optimized design strategies to further improve the walkability of historic and cultural districts. The first chapter introduces the background of this paper, clarifies the purpose and significance of the research, describes the research objectives and methods, and sets out the research framework and technical route. The second chapter is the construction of a framework for the quantitative evaluation system and data augmented design of the walkability in historic and cultural districts, through the improvement of the walkability measurement system of historic districts and the support of data to form the basis of subsequent analysis for optimisation and enhancement. The third chapter uses national and international case studies to obtain an optimised approach for walkability evaluation, the enhancement of multidimensional walkability , the recognition of the relevance of indicators and comprising the selection of targeted evaluation indicators, leading to a specific methodology. The fourth chapter is an empirical study, in which the Changhua historic and cultural district in Guangzhou is selected for the evaluation of various indicators of walkability, and the information is collected and analyzed with various data tools in conjunction with the traditional data to form a comprehensive evaluation and further classification of the streets based on different attributes. Thus provides a stronger support for the later specific design strategies and optimization. The fifth chapter presents the specific optimization design for the walkability in Changhua District according to the problems and opportunities analyzed before. With systematic strategies, general design as well as the enhanced measurements for different streets are put forward to achieve simultaneous improvement of multiple indicators related to walkability, aiming at stimulating the comprehensive value of it, so as to make a positive effect of realizing a sustainable development of Changhua District. The sixth chapter presents the main conclusions, innovations and shortcomings of the thesis. Through the above research, this paper further improves the analysis of the basis and construction of quantitative evaluation of the walkability in historic district, and it can have a positive effect on the optimization of street regeneration.
