In recent years, with the continuous improvement of science and technology and the growing demand for public security, the site selection of security resources is gradually becoming one of the hot research topics in the field of public security governance. In this regard, this paper introduces the Game Idea and unfolds the analysis from the perspective of security resource point site selection and security resource path planning, hoping to improve the emergency efficiency. From scratch, the event diffusion influence factor is introduced to construct the security resource site selection strategy model to realise the site selection decision on regional road network security resource points. Further on, the security resource scheduling path planning platform with u-Dijkstra algorithm as the core under the site selection strategy is designed to realise the path planning for security resource scheduling, providing more efficient decision suggestions that are more applicable to colleges and universities. Finally, combing the traffic network of a campus, we conduct a simulation analysis while designing a small-range security resource path planning. Subsequently, the optimal decision and the optimal route of the safety resource planning are worked out, which demonstrates the effectiveness of the mathematical model in a simulative manner.
