A transit system includes a road, a plurality of pavement markers spaced apart along a lane line of the road, and a plurality of RF devices carried by the pavement markers. The RF devices are configured to transmit RF navigation signals to motor vehicles traveling along the road.

The present invention relates to a road guide post comprising: a supporter (110) which is fixed to the ground by being coupled to an anchor bolt (10), and which is provided in the form of a semicircular body; a guide post body (120) which has a post shape that is screw-coupled to or fitted into the supporter (110), with a concave groove part (111) on the upper outer surface of the body to allow reflective sheets to be attached thereto; reflective sheets (130), multiple layers of which are attached to the concave groove part (111) of the guide post body (120): and a bracket (140) which is inserted and fixed into the bottom surface of the supporter (110) and is used to reinforce the coupling force of the anchor bolt (10).

A system of retroreflectorized traffic control channelizing devices is disclosed. The system comprises a plurality of channelizing devices, each device having a reflective member that is either white, yellow, or red in color. Those having a white reflective member are used to direct traffic from a right side of a traffic lane. Those having a yellow reflective member are used to direct traffic from a left side of a traffic lane. Those having a red reflective member are used to stop traffic for a road closure. A method of use of a system of retroreflectorized traffic control channelizing devices is also disclosed.

Covers for notification, channeling, or delineator devices used to provide notification of immediately proximate or upcoming events, to channel or otherwise direct/redirect traffic flow, or to delineate areas where egress is permitted from areas where egress is not permitted. These covers are generally sized to be disposed on channelizer drums, delineators, cones, barriers, or other channeling devices, are removably securable to such devices, are capable of conveying or communicating information, and can provide alert, information, and/or message communication(s) conveyance to motorized vehicles, non-motorized vehicles, or pedestrians.

A method, apparatus and computer program product are provided for controlling a functional road object. For example, at least one processor receives road sign attribute data indicating at least one attribute of a road sign and receives weather forecast data indicating a weather forecast of a location in which the road sign is disposed. The road sign includes at least one machinery for mitigating exposure to one or more weather conditions. The at least one processor identifies a state of visibility for the road sign using the road sign attribute data and the weather forecast data and generates a control signal for controlling the at least one machinery using the state of visibility.

A self-powered delineator includes a wind-powered rotatable module; a first piezoelectric energy generator module for generating electrical energy; a second piezoelectric energy generator module for generating electrical energy; and a light-emitter. The wind-powered rotatable module includes one or more first magnets spacedly arranged around a rotation shaft. The first piezoelectric energy generator module includes one or more first piezoelectric elements, and one or more second magnets disposed on the at least one first piezoelectric element. The second piezoelectric energy generator module includes at least one elastic base extending radially from a fixed shaft in a cantilever manner; and at least one second piezoelectric element on the at least one elastic base.
