On state DOT projects, practitioners want to know why a project was or was not completed on time, and why a project was or was not on budget. To answer these questions effectively, practitioners must have a framework that allows them to compare projects by type and look for performance patterns. The lack of a standardized method to classify state DOT projects may make it difficult for practitioners to identify trends, and patterns, and to use such information to inform and enhance practice. A standard classification of state DOT projects does not exist. Hence, the objective of this research is to develop a classification framework for state DOT projects based on several differentiating dimensions of state DOT projects. Following a qualitative synthesis research method, a framework that captured the key state DOT project differentiating dimensions was developed. The output of this research includes a classification framework for aggregating different types of state DOT projects. The significant contribution to the body of knowledge on classifying state DOT projects is that basic state DOT project performance analytics can be enhanced within and across the state DOTs by using the project classification framework developed from this research.
