新城市科学视角下的街道微更新技术探索——以上海南汇新城古棕路提升研究为例

The Exploration of Street Micro-renewal Technology from the Perspective of New Urban Science:A Case Study of Guzong Road in Nanhui New City

人本视角的街道微更新依赖于对空间特征与市民需求的精准分析,而传统的分析方法在信度和效度上有提升空间。研究响应我国城市设计转型需求,提出了一个基于新技术的街道微更新策略框架。该框架整合了大、小数据,一方面立足客观视角,基于LBS数据、航拍影像、点评数据等对街道中的人群行为和设施进行评估;另一方面立足主观视角,基于皮电活动(EDA)、皮肤电导(SC)、肌电(EMG)及眼动追踪等监测技术测度的数据对街道使用者的空间感知进行测度,进而实现自上而下与具身循证相结合的空间品质审计,以支持精细化的设计导控。本研究在古棕路对上述策略框架开展了示范性应用,尝试为街道微更新实践探索具有可推广性的新方法。

Street micro-renewal from a human-oriented perspective relies on precise analysis of spatial characteristics and citizens’needs,while traditional analysis methods have room for improvement in reliability and validity.In response to the urban design transformation in China,this study proposes a street micro-renewal technology framework based on new technologies.The framework integrates both big and small data.On the one hand,based on the objective perspective,the behavior and facilities in the street are evaluated based on location-based services(LBS)data,aerial imagery,and review data.On the other hand,based on the subjective perspective,the spatial perception of street users is measured through electrodermal activity(EDA),skin conductance(SC),electromyography(EMG),and eye-tracking data,thus achieving an integration of top-down analysis and evidence-based research to support precise design guidance.This study demonstrates the application of the proposed framework in Guzong Road,exploring a generalizable method for street micro-renewal practices.
