A data expansion system that provides for wireless communication includes a set of roadway communication devices configured to enable vehicle-to-vehicle (V2V) communication. The system includes a first roadway communication device configured to receive data from a first electronic device in a first vehicle and a second roadway communication device communicatively coupled to the first roadway device. The second roadway communication device is configured to communicate the data to a second electronic device in a second vehicle. Each roadway communication device includes a wireless transceiver to transmit and receive data; a communication interface to establish communication links with other roadway communication devices; and processing circuitry to relay the data between the other roadway communication devices or electronic devices in respective vehicles. Each roadway communication device also includes a housing that contains the processing circuitry, communication interface and the wireless transceiver. The housing is configured to be mounted within a roadway surface.

A safety fence support device with flexibility may be provided. More particularly, a safety fence support device with flexibility may be provided which is simply installed on a safety fence used in various sports facilities, e.g., a baseball field, an ice hockey rink, a ski slope, etc., causes the safety fence to be tilted backward even when players playing a game or people enjoying the sports in the sports facilities collide with the safety fence at various angles, thereby preventing injury by mitigating impact applied to a human body through the safety fence, and is used in various sports facilities regardless of the kind of the safety fence by controlling the degree of flexibility for mitigating the impact in accordance with the impact strength.

A road guide post includes: a supporter which is fixed to the ground by being coupled to an anchor bolt; a guide post body which has a post shape that is screw-coupled to or fitted into the supporter; reflective sheets, multiple layers of which are attached to the concave groove part of the guide post body; and a bracket which is inserted and fixed into the bottom surface of the supporter.

A remote controlled mobile traffic control system which can be used in the place of a human flag person. A mobile platform with an adjustable traffic control indicator thereon is controlled by a remote control. The operator can move the platform and change the indication of the traffic control apparatus from a safe distance. The apparatus permits flagging of traffic in a moving traffic control zone arrangement, and operational safety is maximized. A traffic barrier arm is movable between deployed and retracted positions obstructing the path of oncoming traffic, for example by a remote controlled actuator or by remote controlled turning of the platform. A remote alarm unit accompanies to the work crew to alarm them of traffic entering the work zone without authorization or at unsafe speed. The apparatus can travel with a moving or changing work zone, either by human remote control or autonomous follow me functionality.

A pole cover assembly for covering a pole including first sleeves or base sleeves, second sleeves or middle sleeves, and third sleeves or top sleeves or top cap. The pole cover assembly may also contain additional spacer sleeves. The pole cover assembly includes first sleeves, the second sleeves, and the third sleeves which come in front and rear semi-cylindrical tubes that snap together via inconspicuous tabs. Further, each of the first sleeves, the second sleeves, and the third sleeves include a series of disks that accommodate most type of poles i.e., square, round, and U-channel poles. The pole cover assembly acts as a cover for the poles and can snap around almost all types and sizes of poles. The pole cover assembly beautifies and brings visibility to any pole.

Material for a sign support structure, such as a signpost, providing greater visibility an added awareness to the sign comprising a film or sheeting on which is printed contrasting colored segments or contrasting colored designs, words, or letters replicated repeatedly on or within and along the length of the material. The material, when attached to the sign support structure or an independent substrate that is subsequently attached to the sign support structure, provides a higher visibility pattern drawing awareness to the sign.
