摘要： Trafficked pavement substrates utilize markings to segregate traffic (e.g., divide lanes traveling in the same direction, divide sides of the road traveling in opposite directions). A dry polymer modified cement mixture may be used to provide the markings. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water. The location of the lines is identified, and the dry polymer modified cement mixture is applied onto the identified areas as a thin layer. The dry polymer modified cement blend may include polymers to provide colored markings. Glass beads may be embedded into the dry polymer modified mixture before it cures to retroreflect light shined thereon. The trafficked pavement substrate may have troughs formed therein and the dry polymer modified cement markings may be formed therewithin so that the markings are flush.

摘要： A system and method is provided for delivering electric energy to an electric vehicle via electric charging stations or kiosks where an energy delivery point is configured to provide energy to the electric vehicle via a connector or a wireless energy source. The method involves charging an electric vehicle by detecting, using a RFID tag reader associated with an electric vehicle, signals emanating from a marker positioned on the ground, where the marker includes one or more RFID tags, and where the RFID tag reader is able to recognize the signals despite weather conditions where the ground is covered by snow.

摘要： An apparatus, method and system utilize an unmanned air vehicle (UAV) in order to support the definition and use of routes by bicyclists, pedestrians or scooters. With respect to defining a bicycle route a map database is accessed that represents roads segments in a geographic area. The map database contains map data that indicates attributes of the road segments. The bicycle route is then defined from an origin to a destination based upon the map data indicative of attributes of the road segments. In this regard, the bicycle route is defined to include one or more road segments that allow bicycle traffic unaccompanied by a UAV and one or more road segments for which bicycle traffic is unauthorized unless accompanied by a UAV. The bicycle route is subsequently caused to be provided to the bicyclist or a device accessible to the bicyclist.

摘要： A temporary flexible pavement marker comprising a base, a stand and a protective shield wherein at least part of the stand is reflective and the protective shield is configured to prevent materials sprayed down upon the temporary flexible pavement marker from obscuring the reflective part of the stand may be employed in the construction or repair of roads. Since the protective shield prevents asphalt from obscuring the reflective part of the stand during spraying operations there is no need for a technician to remove a protective layer from the markers after a spraying operation.

摘要： A sinusoidal traffic line that has scalloped edges to form a sine wave that increases visibility under conditions of reduced visibility is formed of a pre-cut ribbon or applied traffic line material (e.g., sprayed thermoplastic material). The traffic lines have a wavy left edge and a wavy right edge. The edges are formed in a regular pattern, having a regular amplitude and wavelength relative to a directional vector along the axis of the traffic line. The patterns of the outer edges are arranged in an opposite arrangement such that they converge and diverge. The upper surface of the traffic line can be embossed by an embossed device so as to create a regular pattern and increase reflectivity.

摘要： Disclosed are improved snowplowable pavement markers held fixedly to a roadway by adhesive. The markers include a holder and at least one transversely arranged reflector to retroreflect incident light from headlights of approaching vehicles. The holders have a pocket for supporting the reflector. One or more through openings having angled sides are defined in the bottom of the pocket so that when the marker is installed in an adhesive bed on the pavement, adhesive flows into contact with the holder and the bottom of the reflector to simultaneously affix both to the pavement. Reflectors may be replaced by simply chiseling an old reflector out of the holder pocket to create a flat bottom surface in the pocket to which a bead of mastic adhesive is applied and a new reflector is subsequently installed. This new marker construction applies to both raised and recessed snowplowable pavement markers.

摘要： An autonomous vehicle (AV) can process a live sensor view to autonomously operate acceleration, braking, and steering systems of the AV along a given route. While traveling along the given route, the AV can identify an encoded road stripe in the live sensor view, and decode the encoded road stripe to determine location data corresponding to the encoded road stripe.

摘要： In current highway transportation systems pavement markings guide vehicles along roads. A new system using metallic objects and electromagnetic sensing equipment would enable vehicles to better navigate roads. Metallic objects are placed on roadway surfaces in a similar fashion of existing pavement markings. The metallic objects are patterned to develop a code of information that is detectable using electromagnetic fields. When these fields are detected, the vehicles can be fully or semi-autonomously guided using the information communicated by the metallic filings.

摘要： A mobile platform for assessing and modifying pavement surfaces. An emitter generates electromagnetic waves towards a portion of a pavement surface. A condition sensor receives electromagnetic radiation from a first portion of the pavement surface and generates a first electronic signal representative of a current condition of the portion of the pavement surface. A location sensor generates a second electronic signal containing location data corresponding to the first portion of the pavement surface. A computing platform processes the electronic signals and creates a current pavement condition data point. The computing platform may compare the first electronic signal against a reference representative of a target condition, determine if there is a condition variance, and, if a condition variance exceeds a predetermined threshold, generate a condition control signal which is transmitted to and operates to modify operation of the pavement surface modification system in order to reduce the condition variance.
