Photoluminescent sand preferably includes play sand, photoluminescent pigment, a powdered binder and a curing agent. The play sand is preferably mixed with the photoluminescent pigment to form a photo sand mix. The photo sand mix is then mixed with the powered binder and curing agent to form the photoluminescent sand mix. The photoluminescent sand mix is allowed to cure for between 3-7 days to form the photoluminescent sand.

A road marker apparatus, system and lighting module and corresponding methods of manufacture, installation and replacement. There is a road insert having upwardly facing ridges and an internal cavity with interior surface textures and a tapered front cavity; a boot of incompressible material disposed within the internal cavity of the road insert and form-fit thereto; and a housing body removably disposed within the boot cavity and form-fit thereto. An array of exterior surface textures that operate as a forward operating taper lock between the housing body and the road insert that restricts forward movement and rotation of the housing body with respect to the road insert; and a housing cavity within which one or more physical modules may be disposed. There is a rear lock behind the housing body that prevents rearward displacement of the housing body with respect to the road insert.

A lighted traffic control device is disclosed as it may be implemented to bring attention to approaching lane closures and other work zone strategies a mat configured for placement on a road surface. An example lighted traffic control device includes an independent power source integral with the mat. The example lighted traffic control device also includes an LED lighting circuit having a plurality of LED lights inset into the mat in a configuration corresponding to a road sign. The example lighted traffic control device also includes a control circuit integral with the mat to operate the LED lighting circuit according to a road or lane closure plan.

A road stud includes a terminal storage unit, a light emission unit, a moving body detection unit, a radio communication unit, and a terminal control unit. The terminal storage unit stores preset unique fixed position information. The light emission unit emits a preset light to the surroundings. The moving body detection unit generates a detection signal indicating that a nearby moving body has been detected. The radio communication unit receives, based on fixed position information, an instruction signal for an operation of the light emission unit from a predetermined control system and transmits a detection signal to the control system. The terminal control unit controls a light emission unit based on the instruction signal.

In a road stud system, a road stud includes a terminal storage unit, a light emission unit, and a radio communication unit. The light emission unit emits a light having a first color tone or a second color tone in a first or second direction. The radio communication unit receives an instruction signal for an operation of the light emission unit. A control system that controls a plurality of road studs includes a determination unit and an instruction unit. The determination unit determines whether an overlapping area is in a first state in which passage of a pedestrian is prioritized or a second state in which passage of an automobile is prioritized. The instruction unit sends an instruction signal, in accordance with the result of the determination, regarding the direction of the light emission and the color tone to each of the road studs.
