Quality and Productivity in Transportation Engineering: A Review of Process Optimization and Standardization Practices

Abstract

Transportation engineering plays a critical role in shaping economic growth, environmental sustainability, and social development. As infrastructure demands rise, ensuring high-quality standards and productivity in transportation systems becomes a strategic priority. This review examines the evolution, principles, and practices of quality and productivity management in transportation engineering. It explores process optimisation techniques, standardisation frameworks, and the integration of emerging technologies such as digital twins, IoT, and AI. The study highlights the challenges and opportunities associated with implementing quality management systems (QMS) in road, rail, air, and maritime transport projects. Finally, the paper identifies best practices and future directions for achieving operational excellence and sustainability in transportation engineering.
