Conceptual Model to Support Systematic Use of Performance Measures in State Transportation Agencies

State transportation agencies (STAs) have significant experience in measuring many different aspects of transportation system performance, but they have very limited experience in measuring the performance of the STA as an organization or the performance of programs for which the STA is responsible. Based on research of organizational and program performance measures, a conceptual model to help STAs develop and implement a comprehensive measurement system is proposed. The proposed model helps define the various types of performance measures and illustrates the interrelationships. Examples are offered for each type of measure. The model is flexible and can be adapted to fit unique circumstances and priorities and to focus on the aspects of performance that are most important to a particular organization. After the model and accompanying typology are explained, the utility of the model is described, with examples of beneficial uses.
