Abstract
An apparatus includes a wireless communication system capable of receiving position information for a plurality of workers in a work zone and a position system capable of providing position information for a piece of movable equipment in the work zone. A processor is capable of receiving the position information for the plurality of workers and the position information for the movable equipment and is capable of determining the position of the workers relative to the position of the movable equipment.
Claims17
A system comprising:
- a wireless communication system capable of receiving position information for a plurality of workers in a work zone and a message from a transmitter of a worker;
- a position system capable of providing position information for a piece of movable equipment in the work zone;
- a processor capable of determining positions of the plurality of workers relative to the position of the moveable equipment based on the position information for the plurality of workers and the position information for the movable equipment;
- and
- a display configured to display the positions of the plurality of workers relative to the position of the movable equipment and to indicate which worker's transmitter issued the message.
A system comprising:
- a plurality of signs distributed along a length of a road work zone, each sign assigned a portion of the road work zone and receiving information indicating whether at least one worker is currently in the sign's respective assigned portion, each sign displaying a first speed limit when at least one worker is in the sign's respective assigned portion and a second speed limit when no workers are in the sign's respective assigned portion wherein receiving information indicating whether at least one worker is currently in the sign's respective assigned portion comprises receiving position information originating from devices carried by each of a plurality of workers, the position information indicating a position of a respective worker and wherein the position information for a least one worker is relayed to the sign in part by a vehicle driving past the road work zone.
A construction vehicle comprising:
- a communication system that receives position information for a plurality of workers and a message from a device carried by one of the plurality of workers;
- a position system that determines a position of the construction vehicle;
- an application processor that determines the location of the plurality of workers relative to the construction vehicle;
- and
- a display that shows the location of the plurality of workers relative to the construction vehicle and which worker issued the message.
