| Abstract: |
| The security of public space is the foundation and important precondition for the
sustainable development of city. The frequent occurrence of crowded stampede highlights the
public space security issues. Risk assessment is an effective means of predicting the crowd
risk point and spatial blind area, and is also an important theoretical basis for guiding the
design of public space safety. Based on space syntax theory, taking syntactic parameters such
as integration, connectivity and intelligibility as assessment factors, this paper establishes a
visual quantitative assessment model of public space risk and applies it to the case of Chongqing
Zoo to predict the gathering crowd risk points and spatial blind spots. The results showed that:
firstly, the space with low integration and high connectivity is the predicted risk area for crowd
gathering; secondly, the low spatial comprehension will increase the crowd risk. On this basis,
some important spatial intervention strategies of optimizing the road network structure, planning
the layout of the exhibition area and improving the facilities system are proposed to build a safe
urban public space. |
