An automated roadway marker system that illuminates and provides warning and lane demarcation under poor visibility conditions utilizing IR beam-break transceivers where no deployment considerations need to be made for the first in a sequence, because each marker operationally establishes its linkage condition in an intermittently activated asynchronous pseudo-network. The devices are designed for extremely low power consumption, so that solar energy can be utilized as a power source. The markers can additionally be linked through radio frequency signals, and to provide a warning to mobile and stationary radio frequency receivers. Additionally, the markers can be illuminated via transmissions from mobile and stationary transmitters.
