A roadway system is described, consisting of enhance, smart pavement markers. These smart pavement markers contain elements such as motion sensors, solar cells, radio receiver/transmitters, active lighting and processing capability. These markers can be configured in many ways, including as vehicle speed sensors, and information display systems. Such pavement marker systems can be installed with little or no roadway infrastructure preparation and may be useful for traffic data collection, law enforcement, and vehicle safety applications.
