A road marker disclosed herein includes a single piece of material having a width of approximately three inches or less. The piece includes a top surface, a bottom surface, and a sloped face disposed between the top surface and the bottom surface. The bottom surface is configured to enable the bottom surface to be connected directly to a floor of a channel of a roadway. The road marker further includes a reflector disposed on the sloped face. Another road marker disclosed herein includes a reflecting member including a reflective surface. The road marker also includes a housing configured to support at least a portion of the reflecting member below a surface of a roadway.

A reflective pavement marker for a roadway includes a body having a bottom adapted to be secured to the roadway and at least one a reflector on the body. The reflector includes an outer face for receiving light and an inner face comprising a plurality of light reflecting elements for receiving and reflecting the light back through the outer face. The reflector comprises a light transmitting and thermochromatic polymer adapted to transition at a predetermined transition temperature so as to change the color of the light reflected by the reflector depending on the temperature of the polymer. The predetermined transition temperature can be selected so that the color change of the light reflected by the reflector indicates freezing or near freezing road conditions.

A vision traffic marker network system comprises a plurality of vision traffic markers or traffic nodes configured to capture information such as an event, an environment, a profile, or a condition of an object such as vehicle, human, combination thereof, or the like, for example. The environment information may be time of day, day of week, weather, traffic condition, and the like. The nodes may be one of a traffic node, an ambient node, a repeater, a gateway, or a combination thereof. These nodes are arranged in network neighborhoods and configured to communicate with at least one of the communication networks with at least one of the vision traffic markers or nodes, a control system, the automotive, a server, a global navigation system, other non-vision devices, traffic lights, street lights, electronic devices, or combination thereof, via one more links, either wirelessly or wired communication. The vision traffic marker network system analysis, process, distribute, and report the information to any vision traffic marker network system, client machines, and a server over a network.

Described are retroreflective marker devices, which encode information that can be read by optical sensors, such as LiDAR devices, and that do not detract from human safety. Also described are kits for retrofitting existing markers.
