As the outer space of urban life, alley plays an important role in human life. Recently, with the large-scale urban development, alley spaces have undergone a series of dynamic changes in cyclic repetition, such as growth, decline, and regeneration, making the alley spaces truly suitable for residents gradually disappear. South Korea has been pursuing the revitalization of urban alley spaces through policies such as urban regeneration projects in recent years. According to the latest urban regeneration business report, Busan promulgated the "Regulations for the Revitalization and Support of the Alley Regeneration of Busan Metropolitan City", of which the lawmaker Go put forward that alley is a daily life space and social living space for sharing economy, culture, and environment, mainly roads and spaces focusing on walking. On this basis, to give full play to the value of alleys more correctly, creating attractive alley spaces centered on residents'' lives is the key to urban development.
In the study of the urban alleys, it is necessary to conduct an in-depth study of the activation of the alley spaces through multiple dimensions such as time and space. Although South Korea has been paying attention to the construction and development of alleys through urban regeneration, it has not completely freed alleys from the downturn, especially in night. At present, South Korea is committed to improving the walking conditions and living environment of alleys during the day and night, and gradually promote residents to participate in the activation and support cause of alleys.
Attention to complex alleys recently has gradually increased, and the Urban Renewal Business Group proposed that alleys are "people''s spaces" and "spaces for people". The focus of the innovation and regeneration plan of complex alleys is to respect the daily life of alley pedestrians and let pedestrians directly participate in alley construction rather than fuzzy gathering. While paying attention to pedestrians'' feelings, it is necessary to focus on how pedestrians recognize alley environment, bestow value on it, find and supplement its meaning. Therefore, the breakthrough in the study of complex alleys is to invite residents to provide a comprehensive evaluation from emotional and psychological aspects of alleys, so as to find out the construction direction of urban complex alleys, that are truly suitable for residents’ living. In previous alley regeneration projects, only the construction content related to urban regeneration and the operation guide issued by the government have been given, the data about the pedestrians'' evaluation on complex alleys has not been further reviewed, and the psychological evaluation data of residents on complex alleys has not been perfect, which have led to many difficulties in the design of complex alleys. Under such a research background, it is necessary to conduct detailed studied on complex alleys.
The process of this study is divided into four steps: prior study, empirical study, experimental results, experimental conclusions and future study. Firstly, prior study is conducted to determine the evaluation factors and experimental locations that affect the complex alleys; secondly, empirical study is conducted to determine the questionnaire design, and let same experimental subject to evaluate the experimental sites at the same time, so as to obtain morning and evening 6 data of a residential alley, a business alley, and a green land alley. SPSS is used to analyze the results of the experiment through the comparison of three alleys and the comparison of morning and evening data using the statistical method of corresponding sample T-test. The experimental conclusions are drawn through the correlation analysis and the analysis results of the corresponding sample T-test, and finally the study proposal and future study are summarized.
In this paper, two prior studies are conducted. Firstly, the Jeonju Innovation City, which has been experiencing negative economic growth recently, is selected as the study object through on-site survey and data selection to find specific solutions suitable for the sustainable development of the innovative city. Secondly, 23 evaluation factors are finally classified and summarized through 2 surveys as the evaluation criteria for the complex alleys: 1) 62 psychological factors in 15 materials is summarized, 24 psychological factors that appears more than 2 times are screened out through frequency analysis; 2) the Delphi technique is used to conduct interviews with design experts on the 24 factors to integrate the factors with the same meaning and correct the factors with inappropriate names, and finally the names and definitions of 23 evaluation factors are finally determined.
The conclusions are described by three experimental results, that is, comparison and analysis of the complex alleys of the positivity and negativity of the average value of the corresponding sample T-test, morning and evening data comparison of factors'' significance of corresponding sample T-test, and comparison of complex alleys of correlation analysis.
In the conclusion of the comparison and analysis of the complex alleys of the positivity and negativity of the average value of the corresponding sample T-test, the subjects'' evaluation on "artistry", "safety", "name of road", "culture" and "symbolism" of the residential alley is negative, evaluation on "aesthetics", "artistry", "name of road", "culture" and "symbolism" of business alley is negative, and evaluation on "convenience", "proximity", "name of road", "culture" and "connectivity" of the green land alley is negative. In the conclusion of the morning and evening data comparison of factors'' significance of corresponding sample T-test, one alley has significance (P<0.05) and its T value is positive (+), one alley has significance (P<0.05) and its T value is negative (-), and one alley has no significant evaluation factors. In this study, the factors with peculiar phenomenon are summarized as specific factors, that is, "aesthetics", "street prestige", "street reputation" and "independence". In the conclusion of the comparison of complex alleys of correlation analysis, the specific number of relevant and significant evaluation factors for residential alley, business alley, and green land alley is obtained, it is found that the correlation of the residential alley is the highest the correlation analysis of factors. In addition, five factors that influence the degree of psychological evaluation of the business alley and the green land alley are extracted, that is, "modeling", "mobility (walkability)", "comfort", "culture" and environmental friendly".
