Sensor networks for smart roads

This paper proposes the use of a wireless sensor network of “cat’s eye ” augmented with embedded processing, com-munication, and sensing capabilities to monitor vehicle be-haviour on augmented roads. The primary goal of the sys-tem is to provide drivers with early warning of potentially dangerous situations that may arise. The focus of the pa-per is on the software architecture needed and the technical challenges to be overcome in order to support this and re-lated applications. 1
