MODIFICATION AND ASSESSMENT
The present disclosure involves processes for assessing and modifying pavement surfaces using a mobile platform. An emitter associated with the mobile platform generates electromagnetic waves directed towards a portion of a pavement surface. A condition sensor associated with the mobile platform 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 is used to process the electronic signals and create a current pavement condition data point. The computing platform may compare the first electronic signal against a reference representative of a target condition of the portion of the pavement surface, determine if there is a condition variance, and determine whether any condition variance exceeds a predetermined threshold. If a condition variance exceeds a predetermined threshold, the computing platform may generate a condition control signal which is transmitted to a pavement surface modification system, and which operates to modify operation of the pavement surface modification system in order to reduce the condition variance.

Preformed Reflective Line Marking for Roadways and Associated Methods Thereof
A preformed thermoplastic roadway line marking includes a preformed thermoplastic substrate layer capable of being attached to a roadway, and a preformed thermoplastic upper layer in contact with the substrate layer. Advantageously, such an upper layer includes a surface area having a plurality of spaced-apart slits. The slits penetrate through an entire cross-sectional thickness of the upper layer and are in fluid communication with the substrate layer. When heated to a liquid state, the substrate layer has a morphed shape and is at least partially displaced upwardly through the slits and disposed on the upper layer such that the upper layer is fixedly locked to the substrate layer and maintained at a substantially stable position relative to the substrate layer. Such a structural configuration provides an unexpected and unpredictable result of insuring the marking is locked into place relative to the roadway, thereby reducing labor costs and improving durability.

Temporary flexible pavement marker
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.
PAVEMENT MARKINGS AND PAVEMENT MARKING SYSTEM FOR LANE IDENTIFICATION
In one aspect, the present application relates to dark-colored retroreflective pavement markings. The dark-colored retroreflective pavement markings may be used in a system that provides information about the arrangement of pavement markings to a sensor on a vehicle. This arrangement may be used to aid in the identification of a particular lane on a roadway. The pavement marking system comprises a sensor placed on a vehicle and at least a first pavement marking and a second pavement marking, wherein each of the first pavement marking a second pavement marking comprising different properties
Retroreflective traffic stripe for both dry and wet weather conditions
A retroreflective traffic stripe comprising an exposed top surface containing a widely spaced repeating pattern of linear light-turning prisms over a bottom surface containing two different types of cube corner retroreflective prisms. The light-turning prisms are configured to use refraction and reflection to redirect light from distant headlights into a downward direction onto the bottom surface of the traffic stripe. Cube corner retroreflective prisms of the first type on the bottom surface have optical axes which are substantially perpendicular to the surfaces of the traffic stripe and are located substantially beneath such light-turning prisms. Cube corner retroreflective prisms of the second type on the bottom surface have optical axes tilted toward the distant headlights by at least 25 degrees and are located substantially between such light-turning prisms. Under dry road conditions, the light-turning prisms and first type of cube corner prisms provide unprecedented levels of retroreflectivity. Under wet road conditions, the second type of cube corner prisms provide high levels of retroreflectivity.
Method and System for Charging Electric Autonomous Vehicles
A system and method is provided for delivering electric energy to an electric autonomous vehicle. Autonomous vehicles are guided to electric charging stations or kiosks where an energy delivery point is configured to couple to the electric autonomous vehicle via a connector or a wireless energy source. The energy delivery point delivers energy to the electric autonomous vehicle via the connector. The AV is guided via the use of specialized lane marking components that permit unprecedented sensor feedback despite adverse weather conditions, which presently pose problems experienced by self-driving systems that rely upon vision based camera systems.

An emitter associated with the mobile platform generates electromagnetic waves directed towards a portion of a pavement surface. A condition sensor associated with the mobile platform 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.

The computing platform may compare the first electronic signal against a reference representative of a target condition of the portion of the pavement surface, determine if there is a condition variance, and determine whether any condition variance exceeds a predetermined threshold. If a condition variance exceeds a predetermined threshold, the computing platform may generate a condition control signal which is transmitted to a pavement surface modification system, and which operates to modify operation of the pavement surface modification system in order to reduce the condition variance.
