Development and validation of a sensor-integrated smart driving test system for automated, scalable, and objective driver performance evaluation

Evaluating driver proficiency remains a fundamental determinant of road safety, regulatory adherence, and public confidence in licensing systems. This paper presents the Smart Driving Test System (SDTS), a fully integrated, sensor-based, microcontroller-driven framework designed to automate and standardize the assessment of driving skills. A functional prototype demonstrates SDTS capability to replace subjective human judgment with objective, repeatable, and data-centric performance metrics. The work includes a comprehensive feasibility analysis encompassing technological maturity, economic viability, operational deployment, and legal compliance, further supported by a detailed cost estimation model and implementation strategy. A comparative assessment with established international smart driving evaluation platforms underscores SDTS's distinctive contributions in communication architecture, modular hardware configuration, graphical user interface functionalities, and scalable system design. The paper also outlines prospective enhancements, including the incorporation of machine learning for predictive performance analysis, adoption of low-power wireless communication protocols such as ZigBee and LoRa to simplify installation, utilization of cloud-based analytics for centralized monitoring, and employment of multimodal sensor fusion to improve environmental perception. By bridging the gap between conventional manual testing procedures and next-generation automated evaluation, SDTS significantly enhances the transparency, consistency, and reliability of driver certification processes. Furthermore, it lays the groundwork for the digital transformation of transportation licensing infrastructure and aligns with broader advancements toward intelligent transportation ecosystems, promoting safer roads, harmonized assessment standards, and strengthened public trust in driver qualification frameworks.
