A method of installing and removing traffic control or traffic regulating devices. More particularly, the method includes the installation and removal of automated switchable road signs or flaggers. The safety assistance device and method in accordance with the invention envisions added safety for those installing and removing traffic control or automated flagger devices. Also, the safety assistance device and method of the invention is initiated without requiring a manual activation by those installing or removing the traffic control device.

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.

The robotic maintenance vehicle (RMV) has a propulsion system, a control system, an electrical power source, a maintenance module, a multi-axis robot, an optical system, and a location translator. The maintenance module is configured to hold different kinds of road maintenance materials. The multi-axis robot is configured to convey the road maintenance material from either the maintenance module to the road, the road to the maintenance module, or both. The optical system and the location translator are configured to be controlled by the control system and operate in conjunction to instruct the multi-axis robot where to pick up and/or place the road maintenance material. The multi-axis robot is configured to be selectively coupled to a distal arm tool.

A bollard system having a bollard, a carrier device, a lock plate, and a cover plate is provided. The bollard may be rotatable between a deployed configuration and a stowed configuration. The carrier device may have a recess adapted to carry the bollard in the stowed configuration, and may be adapted to be recessed within the ground. The lock plate may be adapted to maintain the bollard in the deployed configuration. The cover plate may be carried by the carrier device and adapted to cover a portion of the recess. The cover plate may be moveable between an opened position and a closed position. When the cover plate is in the opened position, the bollard may be rotatable between the deployed configuration and the stowed configuration. When the cover plate is in the closed position, the cover plate may be configured to be flush with the ground.

A system for generating collision data captured by safety monitoring equipment on-board 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.
