Abstract

In order to solve the problem that the traditional method is very complex in safety assessment of primary and secondary school, which cannot get an objective result quickly. The method of calculating the natural visibility ratio within the students' effective range of visibility is studied based on graph theory, which can assess the safety level of public space in a quantitative way. Through this method, 42 primary and secondary schools were used to investigate to get the value of natural visibility ratio, and which was used to analyse the natural visibility level of those schools. The results show that natural visibility ratio can quality identify potential unsafe factors in campus. There is a strong negative correlation between campus average natural visibility ratio and building density. Therefore, the natural visibility ratio is beneficial to quality and objectively evaluate the safety of the campus, and to improve campus planning and design by predicting the level of visibility in public space.
