  • Patent number: 8711004
    Abstract: One estimate indicates that rubbernecking and congestion consumes about 4% of this country's fuel. Two approaches are presented to help solve this problem. The first uses shields to block the view of a car accident. Rubbernecking is reduced since the visibility of the car accident is reduced. A second approach uses mobile flat units that can be remotely controlled to enter a roadway that is carrying active traffic. The traffic runs over these units that are being moved until the master processor indicates that the mobile flat units are in position. A post is extended from the flat unit that issues commands to the motorists so the master processor can begin to control and reduce congestion. Both approaches can be used to help decrease fuel waste in the US.
