Walkability Evaluation Study Of Neighborhood Street Under The Concept Of Park City

Slow moving is an important form of human activity,which can not only meet the needs of healthy travel,but also improve the quality of life and ecological environment.Walking is one of the common forms of slow moving,which has sustainable characteristics such as nature,health,cleanliness and low cost.As an important carrier of walking,streets carry multiple functions such as traffic,social interaction,and recreation,and their environmental quality can directly affect people’s driving force for slow walking.Walkability is an indicator to measure the degree of support and encouragement for walking in built environment.The existing research and planning practice focused on the traffic function of the slow traffic system or the traffic behavior of the slow traffic subjects,as well as the ecological value assessment of the slow greenway,but less on the identification and precise matching of the use needs of the slow traffic subjects.There are also few localized case studies on walkability.In the face of rapid urbanization and highspeed life rhythm,how to reduce people’s "fast food" life burden through walking and how to promote a healthy lifestyle by strengthening the willingness to walk outdoors are one of the research focuses in the process of park city construction.Based on the existing research content of slow walking system,this paper,this paper deeply analyzes the concept connotation of park city,and puts forward three aspects that should be considered in walkability evaluation under the concept of Park City.First,we should expand the demand for slow travel.In addition to the rigid life needs of daily commuting and shopping,we should pay attention to the spiritual perception needs of residents,mainly including safety,comfort and aesthetics.The second is to expand the slow walking space.It not only pays attention to the linear main space within the red line of urban road,but also evaluates whether the open neighborhood space inside the block can effectively meet the needs of residents for slow walking activities.The third is to explore the differences in residents’ perception of the current street space under different attributes and activities,so as to give more precise feedback on the demand for slow walking.Therefore,in order to explore a complete city-level walkability evaluation system,this paper takes Qingdao as an example to evaluate the walkability of neighborhood streets in Shinan District,one of the economic development centers with a strong historical and cultural atmosphere.The experiment mainly uses EAPRS method to obtain residents’ perception of neighborhood street walking environment in Shinan District through field visit,expert group discussion and questionnaire survey.Principal component analysis(PCA)was used to determine five first-level pedestrian awareness indexes,namely,traffic safety,stop-friendly,traffic disturbance,visual richness and diversity of the first floor.Structural equation model was constructed to further quantify the interaction between walking intention and five indicators as well as each level of indicators.The results show that travel intention to walk is directly affected by “traffic safety”“stop-friendliness” and “visual richness”,i.e.commuting behavior is mainly affected by“traffic safety”,recreation and exercise are mainly affected by “stop-friendliness”,and shopping and consumption are mainly affected by “visual richness”.In addition,there are differences in the cognition factors of walking sex in different gender groups.Women generally have a higher perception of safety than men,and pay more attention to the functional experience of first-floor buildings than men.In general,staying space and rest facilities have been proved to be factors of high demand.The results of this study can provide theoretical basis and practical suggestions for quantitative evaluation of street walkability and street vitality improvement in similar areas.
