Driver performance appraisal using GPS terminal measurements: A conceptual framework

Objective measurement for performance appraisal is vital but rarely conducted in a methodologically sound manner. In this paper, we provide a thorough assessment of how objective and fair performance appraisals of drivers can be conducted. Furthermore, a unique conceptual framework is provided for evaluation of safety interventions and operational performance through monitoring quantitative driver performance measures. The conceptual framework makes use of online‐measurements obtained from Global Positioning System (GPS) terminals, and the data are evaluated using statistical process control (SPC) tools. SPC tools are useful in comparing individual driver performance to overall performance as well as for identifying time‐dependent factors that influence performance. Quantitative performance measures considered in the study include speed violations, vehicle idle duration, and fuel consumption. As an illustration of the concepts and implementation at a logistics firm is provided.
