Applying DEA Technique to Estimation of the Optimal number of Traffic Policemen in Police Stations

Increasingly, police stations are asked to justify their use of resources in terms of producing meaningful services and impacts to the users and the parent organisations. This study applied an analytical technique called Data Envelopment Analysis(DEA) to calculate the relative efficiency of two hundred and thirty nine police stations especially with regard to the task of traffic policemen and to estimate the optimal number of traffic policemen of each police station through analysis of production relationship between inputs and outputs. It is found that there are significant gaps in productivity development level among metropolitan, urban, and rural police stations. It is also found that the DEA-based approach provides a good tool to estimate the relative technical efficiency of the police stations, to support setting up policies and strategic decisions for improving the performance of traffic policemen, and to rationalize the allocation method of human resources among the police stations.
