Abstract: The invention detailed herein provides for a new method of improving the vehicular capacity of a conventional road by utilizing at least one conditionally adjusted speed (CAS) limit who's adjustment is based upon at least one seasonal and/or situational parameter or guideline. Moreover, the implemental rapidity of CAS limits is also superior to most solutions presently under consideration because their integration into existing traffic control systems does not create any appreciable technological, implemental or legal difficulties. This method therefore, not only improves the overall vehicular capacity of conventional roads but does so without increasing either driver or governmental costs. Reductions in the use of fuel and land as well as diminishing the overall travel times, accident rates, and emissive pollution associated with vehicular transportation are other distinct benefits also provided by this method.

Abstract: In a method of fishing utilizing the flippin technique, a loop of line is drawn from between two eyelets, rather than from between the reel and an eyelet. A flippin rod (10a, 10b) has an additional eyelet (27) mounted between the reel (13) and the closest guide (19) of a plurality of conventional eyelet fishing guides (16-19).
