Traffic sign detection and analysis: Recent studies and emerging trends

Traffic sign recognition (TSR) is a research field that has seen much activity in the recent decade. This paper introduces the problem and presents 4 recent papers on traffic sign detection and 4 recent papers on traffic sign classification. It attempts to extract recent trends in the field and touch upon unexplored areas, especially the lack of research into integrating TSR with a driver-in-the-loop system and some of the problems that presents. TSR is an exciting field with great promises for integration in driver assistance systems and that particular area deserves to be explored further.
