Embodiments of safety trucks incorporate multiple connection points to which a variety of attachments, or combinations of attachments, can be releasably and interchangeably coupled to enable their use with increased effectiveness to safeguard roadway construction, maintenance and repair personnel as they perform tasks within or relatively near to roadway workzones and worksites. Also, methods of operation of the safety truck embodiments enhance their ability to guard and protect roadway construction, maintenance and repair personnel while they work within or relatively near to roadway workzone and worksite locations.

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.

A traffic control signal apparatus that is configured to be releasably secured to a hitch receiver on a vehicle wherein the traffic control signal apparatus is operable to provide traffic signals to approaching vehicles. The present invention includes a frame having an upper portion and a lower portion wherein the lower portion is coupled to the vehicle. The upper portion has a light unit secured thereto and the light unit includes a first light and a second light configured to illuminate colors providing approaching vehicles traffic signals. A sign support member is movably secured to the frame and includes a sign secured to the end distal to the frame. A sign is secured to the distal end of the sign support member and is configured to provide traffic instructions to approaching vehicles. The traffic control signal is electrically coupled to the vehicle and includes a control panel for operation.

A trailer-mounted system and apparatus are provided to improve safety at road construction sites and other locations by allowing drivers to be signaled, and one or more lanes of traffic blocked, without having a flagger stand in or immediately adjacent to a road that is carrying traffic. The system and apparatus may have extensive data and audio and video networking capabilities to allow for remote control of the system and/or observation of the construction site. These networking capabilities may allow the system to further serve to enhance collaboration among remote worksites.

A variant apparatus may be mounted on a highway divider such as a K-rail instead of a mobile trailer. Another variant provides a portable kiosk containing apparatus to supply the data networking and collaboration functions without the mechanical apparatus used to block traffic.

A system for generating collision data captured by safety monitoring equipment on-hoard a safety truck may include a processor that receives an indication of a speed of a vehicle approaching the safety truck and that overlays a textual indication of the speed of the vehicle onto frames of video captured of the vehicle. If the processor receives an indication that the vehicle has collided with the safety truck, a timestamp is associated with the video and a predetermined portion preceding the timestamp and after the timestamp is not overwritten.

Right and left safety module embodiments are designed to be installed in insets located midway along right and left sides of flatbed trucks. The modules provide man baskets that have lower and upper platforms. While the truck is being driven alongside a roadway work zone, a workperson standing on the module's lower platform either 1) moves traffic delineators one at a time from the upper platform, and then places the delineators at spaced locations alongside the roadway work zone, or 2) removes traffic delineators one at a time from spaced locations alongside the roadway work zone, and then places the delineators onto the upper platform. Vertically movable safety rails and pivotal safety gates of the modules prevent falls from the modules of workpersons standing on the lower platform.

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.
