Streets are an important part of urban public space,and also serve as the breakthrough point of governance in urban renewal.Focusing on the governance effectiveness of street space,using London Healthy Street evaluation system as reference,and combining street view image quantification cognition and emotional perception technology,this paper aims to construct the subjective and objective measure-ment framework for effectiveness of street space renewal governance from the dimensions of perceived safety,travel friendliness,spatial order,experience comfort,and environmental pleasure under the perspec-tive of healthy streets.And based on multi-temporal street view images,an evaluation index system is es-tablished,which includes 5 primary indicators and 16 secondary indicators,so as to design a large-scale quantitative measurement method for the evaluation of effectiveness of street renewal governance.Finally,the paper proposes the governance strategies of street renewal from the dimension of spatial co-gover-nance and experience improvement.Firstly,establish and improve the co-construction,co-governance and sharing mechanism,and enhance the management,operation and maintenance mode of street renewal;sec-ondly,ensure the right-of way of green travel space and improve the safety of street space;thirdly,inte-grate the elements of street space and optimize the order of space scenes;fourthly,optimize the allocation of street space resources and create a travel-friendly environment.
