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.

An emergency response barrier is shown and described, the barrier having a frame with reinforcing bracing; two axles coupled to the frame with wheels attached thereto; a king pin coupled to the frame; 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:
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 including first and second platforms, at least one of the 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 each wall section has a plurality of full height and partial height wall members, the full height wall members extending substantially the height and width of the wall section and the partial height wall members extending substantially the width but less than the height of the wall section, the full height and partial height members alternating along a length of the wall section.
Abstract:
The present disclosure is directed to a computer that receives weather information from a weather service provider (“WSP”) server and automatic vehicle locating system (“AVL”) collected information from an AVL server, accesses a material performance specification for at least one treatment material, and determines, based on the weather information and/or AVL collected information and the material performance specification, a treatment recommendation for a selected roadway segment and/or route.
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, in response, receive maps and operator instructions.

Abstract:
The present invention is directed to the use of mobile sensors to collect temperature information used to control, inter alia, rail vehicle speed, acceleration, or scheduling.
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.
