First I will give an introduction to our project. Taiwan entered an aging society in 1993 and turned into an aging society in 2018. It is estimated that the country will join a super-aged society by 2025. It is crucial to consider the safety and accident prevention needs of the elderly during the movement so that the elderly could take adequate exercise and will not suffer from social isolation. Properly arranging police officers in the moving routes is very important to ensure the safety of the elderly.
In order to cope with the safety of the elderly's movement and activities, we use the following steps to arrange the police force
Set the weight of the elderly.
(2) Use weighted K-means to make the elderly who need more care closer to the center of the cluster, so that the police officers can be arranged closer to the elderly.
(3) In order to make the elderly more active outdoors, the movement mode is set to walking, and the route from the elderly to the path is the shortest path between the activity site and the residential gathering point, and the shortest path tree is constructed.
(4) Due to the insufficient number of police officers, in order to serve as many elderly people as possible with as few police forces as possible, the intersections most frequently passed by the elderly are used as reference points for police dispatching.
(5) Use the breadth-first search method to calculate the number of people passing through each intersection, and the number of people at the multi-path convergence point is the basis for recommending police force arrangements.
