Research on Open Campus Space Evaluation System Based on CSOA Theory

摘要

As an important part of urban open space,campus space plays an important role in connecting urban traffic environment with the gradual improvement of urban space quality today.Based on CSOA(Campus Space Openness Assessment)theory,the paper calculates the current situation of walking space and vehicle crossing space in the campus,including entrance coupling degree(ξ),campus crossing degree(ε)and campus space opening degree(∑).The coupling relationship between campus entrance layout and campus road form for campus space openness is analyzed and the strategies are optimized respectively.The conclusions are as follows:①the location of campus entrances and exits can be reflected by the coupling degree of campus entrance,which is affected by the number and nodes,and the coupling degree is positively correlated with the number;②the closer the azimuth distance between the two entrances and exits on the campus to the linear distance,the higher the crossing rate;③the higher the product of campus entrance coupling degree and campus crossing degree,the higher the campus space opening degree.The results of this study provide quantitative guidance for modern campus design from the perspective of open campus space evaluation system.
