1. A roadway stud comprising:
a processor;
a wireless communication interface electrically coupled with the processor;
a vehicle detector electrically coupled with the processor;
a global positioning system (GPS) receiver electrically coupled with the processor; and
a light source electrically coupled with the processor, wherein:
the processor is configured to:
transmit a location of the roadway stud via the wireless communication interface; and
illuminate the light source upon receiving a first activation signal via the wireless communication interface;
the GPS receiver is configured for reducing distance error occurring when installing the roadway stud on a roadway;
and
the light source and the vehicle detector are configured for:
allowing the roadway stud to be installed to identify a lane boundary to a driver of a vehicle when approaching the roadway stud; and
detecting a presence of the vehicle when passing the roadway stud.
