Abstract: In one embodiment, a safety trailer has semi-tractor hitches at both ends and a safety wall that is fixed to one side of the trailer. That side, however, can be changed to the right or left side of the road, depending on the end to which the truck attaches. A caboose can be attached at the end of the trailer opposite the tractor to provide additional lighting and impact protection. Optionally, the trailer can be equipped with overhead protection, lighting, ventilation, onboard hydraulics, compressors, generators and other equipment, as well as related fuel, water, storage and restroom facilities and other amenities.

Abstract: A mobile barrier is shown having first and second platforms, at least one of the first and second platforms engaged with an axle and a set of wheels; a safety wall assembly, having a mechanism for translation of the safety wall from one side of the platforms to another, the safety wall further having telescoping first and second portions allowing the safety wall assembly to expand and retract in length along the longitudinal axis of the mobile barrier; a plurality of variable length braces connected to the platforms and the safety wall, which expand and retract as the safety wall moves from one side of the platforms to the other.

Abstract: A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a ballast coupled to the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein the vehicle is provided with an mechanism for locking and unlocking the brake system.

Abstract: An emergency response barrier is shown and described, the barrier having a cab and engine for propelling the barrier; a frame with reinforcing bracing; two axles coupled to the frame with wheels attached thereto; wherein the frame is covered with a substantially planar skin that extends along the right and left sides of the frame, from a top of the frame down to a lower edge and covers a majority of the wheels on each side of the barrier; an impact attenuator coupling on the frame, having a vertical pin received in a bore disposed on an impact attenuator, and configured for rotation about the vertical axis of the pin; and a hydraulic cylinder connected between the frame and the impact attenuator, wherein retraction and extension of the hydraulic cylinder moves the impact attenuator through an arc of rotation about the vertical pin.

Abstract: A safety trailer is shown including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; and wherein the trailer supports a ballast member, the ballast member being positioned near a first side of the trailer and the wall sections near a second, opposing side of the trailer, the ballast member offsetting, at least partially, a weight of the plurality of wall sections.

Abstract: A towable crash-attenuating vehicle is shown having a frame; at least two axles coupled to the frame, each of the axles having wheels attached thereto; a T-shaped ballast coupled to the frame, and oriented such that the weight of the ballast is biased toward the front end of the frame; deflection shields coupled to the right and left sides of the frame, wherein the deflection shields cover the frame and a majority of the wheels on each side of the vehicle; a tow connection coupled to the front of the frame, pivotable from a deployed state to an undeployed state; an impact attenuator coupled to the rear of the frame; wherein the vehicle is provided with a brake system, and wherein said brake system may be locked and unlocked and wherein the vehicle is provided with an on-board mechanism for locking and unlocking the brake system.

Abstract: The present invention is directed to differing embodiments of safety trailers, which have first and second platforms and a safety wall positioned therebetween. The platforms and safety wall define an area protected from vehicular incursions.

Abstract: A method and system are provided in which maintenance vehicles collect information from sensors and operators, forward the collected information to a server, and, is response, receive maps and operator instructions.

Abstract: Selected types of information are collected from various sources and a portion thereof transmitted to a remote server. The remote server dynamically compiles and processes this data with information from other similar and separate sources and provides useful and relevant information, such as vehicle and location specific road maintenance radar, forecasts and treatment recommendations, and then transmits the data back to the vehicles in the field for one or more of the appropriate deployment of equipment, instructions and the automated or manual application of materials.

Abstract: A safety trailer is shown including first and second platforms, at least one of said first and second platforms having an axle and wheels attached thereto; a plurality of interconnected wall sections positioned between and connected to the first and second platforms, the plurality of wall sections defining a protected work area on a side of the trailer; The axle of the trailer is engaged with a vertical adjustment member configured to selectively adjust a vertical position of the surface of the trailer.
