Method and system for carrying out optimal police dispatching based on road safety index

Abstract

The invention relates to a method and system for carrying out optimal police dispatching based on a road safety index, and the method comprises the following steps: (1) collecting data, including road network data, road condition speed, date and time, traffic accident data and weather data; (2) calculating a road safety index, wherein the road safety index comprises a regional safety index and a road safety attribute; (3) calculating a road network safety objective function, calculating the road safety objective function according to the road safety index, and adding the safety objective function values of all roads of the road network to obtain the whole road network safety objective function; (4) optimizing police deployment until the road list or the police officer list is empty; and (5) outputting a police dispatching task list. Police deployment and road real-time safety conditions are combined, so that the police deployment is more reasonable, the accident occurrence amount is reduced, the police time is shortened, accident casualty treatment is more timely, life and property losses of people are reduced, road network congestion is relieved, and the police are saved.

Description

technical field [0001] The invention relates to a method and system for optimal police dispatching based on road safety index, belonging to the technical field of urban road traffic safety. Background technique [0002] At present, the number of vehicles in cities is increasing, roads are becoming more and more congested, and the number of traffic accidents is increasing. Once a traffic accident occurs, if the traffic police cannot arrive at the scene of the accident and deal with it in time, it may cause greater damage to people's lives and property. Losses, and cause abnormal and continuous congestion of urban traffic. [0003] Although the number of people's police in our country has increased greatly, it still cannot keep up with the pace of social development. Facing the shortage of police force, it is more important to rationally optimize the deployment of police force resources. The traditional police dispatching strategy is generally divided into fixed grids by the...

AI Technical Summary

Problems solved by technology

The traditional police dispatching strategy is generally divided by the leaders of each traffic police brigade and squadron into a fixed grid and assigning fixed personnel to patrol, but there are certain shortcomings, that is, the security situation in each place is different. , Different locations have different security conditions, and the probability of accidents is also different. The deployment of fewer police forces in more dangerous places will cause insufficient police force; the deployment of more police forces in safer places will cause idle police force

This leads to the disadvantages of deploying a large police force, low deployment efficiency, and long time consumption. The deployed police force often cannot meet the actual work needs when dealing with sudden traffic incidents.
