Abstract

This paper introduces relatively new technological trends in engineering and enforcement approaches used for speed management. Specifically, this paper introduces the trends involving “Intelligent Speed Adaptation (ISA)” and “Average Speed Enforcement”, which have been studied and demonstrated in European countries since around 2000, and “portable Orbis”, which is a new speed enforcement technology in Japan. This paper then describes the approaches used to evaluate the impact of speed enforcement.
