Abstract: This method increases the number of lanes immediately preceding and immediately following a given intersection. When the traffic signal is red, vehicles must come to a stop. When the traffic signal turns green, vehicles traverse the intersection and enter the stretch of road immediately following the intersection (3). Of these, vehicles in the priority lanes (6) move on while those in the non-priority lanes must slow and/or stop. When the traffic light turns red and all vehicles from the priority lanes have safely left the area, vehicles in the non-priority lanes can safely merge back into the priority lanes and move on. This method results in a tremendous increase in the traffic flow rate in intersections.

Abstract: This invention describes a new method of supplying a moving automobile with electricity. Electrodes placed beneath the automobile pass over electrodes embedded in the roadway. The capacitance between the electrodes beneath the car and the electrodes embedded in the roadway closes the circuit and high voltage pulses or a high voltage sinusoidal signal is transferred from the electrodes in the roadway to the electrodes beneath the car. This power is used to charge the car batteries. Hence the charging occurs while the automobile is in motion so that the automobile can travel from city to city without ever stopping.

Abstract: The proposed design of the Butzek-Troemel Roundabout, or spiralabout, provides a number of substantial improvements over traditional multilane roundabout design principles. By providing a generally outward spiraling lane design instead of a continuously circulating lane design, approach capacity, departure capacity, and circulating lane utilization are all enhanced. Vehicle conflict points are reduced compared to standard roundabout designs with as many approach lanes, thus improving safety. The design provides a viable alternative to traffic signals at significant multilane intersections, and an improvement on the roundabout, an emerging design concept in the United States.
