Transport Management for Vehicles Routing Arrangement: A Case Study of Prevention and Suppression Patrol of Thai Police Stations

Coronavirus disease has affected economics and society, resulting in increasing crime problems. Under circumstances with limited patrol officers, prevention and suppression operations must be analyzed for vehicle routing for prevention and suppression patrols to reduce the patrol distance, time and fuel. This research aims to analyze the vehicle routing arrangement of prevention and suppression patrol officers and to develop a routing process model of prevention and suppression patrol management. Quantitative research is applied with the traveling salesman problem (TSP), which is utilized to establish prevention and suppression patrol routes. Qualitative research is applied with content analysis, which is utilized to develop the routing process model. The vehicle routes of the prevention and suppression patrol are arranged in the route set. These results show the average route, distance and shortest patrol time of the patrol officers, which cover all risk point patrols. Additionally, a patrol routing model is presented to arrange the process of prevention and suppression patrol operation. This key process is applied to manage the prevention and suppression patrol well, and these benefits are to reduce the patrol distance, patrol time and fuel cost. Additionally, this practice has increased the patrol rounds at risk points, resulting in the reduction in crimes and upgrading good practices in patrol operations.
