Street space is an important part of public space in cities, and the connection of street space among city districts directly affects the development of the city. Coastal cities are densely populated, and people's increasing demand regarding quality of life has put higher requirement on the quality of street space in cities. This research adopted quantitative analysis to study the quality of street space in coastal cities, and takes the north downtown district of Qingdao City, a coastal city in China, as an example to quantitatively evaluate the quality of street space in coastal cities. The research results show that human activities have a very important role in street space. The composition of street space in coastal cities includes the external representation and the spatial constitution. The quantified morphological features include interface density, alignment rate and uniformity, etc. Through the analysis results of the quantitative research of the interface density and alignment rate of the streets in the north downtown district of Qingdao City, it was found that, in general, the sense of closeness, continuity, and orderliness of the street space is good. This article provides a theoretical basis for the quantitative analysis of the street space in coastal cities.
