A road network-based optimization method for police patrol and interrogation routes

Abstract

The invention provides a police affair patrol interrogation path optimization method based on a road network, and the method comprises the steps: generating a series of path grid basic units based onan urban road network structure, and extracting all grid basic units covered by a crime hotspot; Marking according to the crime risk level to which the crime number belongs; Combining the grid basic units with the same crime risk level according to the position relationship among the grid basic units to obtain independent grid units; calculating crime risk weight values of the road section and theintersection by taking the number of crimes in the independent grid unit as a crime risk weight value of the independent grid unit; Sequencing is conducted according to the crime risk weights, and corresponding road sections and intersections are selected as priority choices for police affair patrol inspection. According to the method provided by the invention, corresponding guidance can be provided for formulation of police patrol schemes of public security departments, and the working efficiency of patrol inspection can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of crime analysis and public security prevention and control, and in particular relates to a road network-based police patrol interrogation route optimization method. Background technique [0002] With the rapid development of public security informatization, Police Geographic Information System (PGIS), as an important geographic information analysis platform, has become an important basic tool in public security work. played an important role in handling incidents. In recent years, with the implementation of the public security big data strategy, the public security department has successively collected and collected a large amount of basic information data, and relied on the police geographic information platform to store and manage these data resources, and according to the needs of various public security business departments Carrying out data analysis and related applications, criminal space intelligen...

Problems solved by technology

In terms of police patrols and investigations, the current main strategy is to deploy additional police forces to areas or road sections where crime hotspots are located or to increase the patrol frequency of existing police forces, and to increase the deterrence of potential criminal groups by increasing the police presence rate on the street. Effective prevention and control of crime risks, but this working method is more effective when the area of ​​crime hot spots or the length of road sections is relatively limited. Once the area covered by crime hot spots is large or the road network structure in hot spots is complex, it will Huge requirements are placed on police resources or work intensity for patrol and interrogation, which is often difficult to achieve under the current situation of very tight police resources
