  • Publication number: 20090038902
    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: A highway system for vehicular traffic which includes an intersection between a main road and a secondary road, each having two traffic directions separated by a center line. The main road has a barrier along its main section for preventing direct crossing by traffic from the second road, and bypasses for each traffic direction. It further has barriers for directing traffic into the bypasses. A further barrier defines a return stretch of the bypass, the return stretch not having a barrier and being such as to permit merging of the two opposite directions of the main road traffic.

  • Patent number: 5807020
    Abstract: Traffic guide constructions at road intersections to provide smooth traffic flows thereof and the methods of traffic control with these traffic guide constructions mainly include overhead bridges and/or underground tunnels extending in parallel to a main road and one or more branch road intersecting with the main road to cross the intersections thereof so as to avoid traffic jams thereat. Cars may move on the main and the branch roads straight forward without being interrupted at the intersections. Cars moving on the main and the branch roads can make turns to either sides by using the tunnels under the overhead bridges or the turnarounds above the underground tunnels to avoid interfering with the cars moving straight forward and causing any traffic jams at the intersections.

  • Patent number: 5795095
    Abstract: A right hand traffic intersection at grade of four roadways and method of directing vehicles to cross an intersection center bidirectionally along two opposed roadways in Phase 1, along the other two roadways in Phase 2, and to make simultaneous protected left- or U-turns from all four roadways, with through-traffic stopped, in Phase 3 of a 3-phase signal cycle. Two left turn passages in each roadway located between incoming and outgoing main lanes terminate at the intersection center at two locations, cross at an interchange zone some distance from the center and connect to the main lanes yet farther from the center. Vehicles making a left turn enter the center from the left passage whereas traffic arriving from a left turn enter the right passage. This keeps all left turn tracks in the center apart. Traffic signals control traffic at the intersection center and interchange zones. The design and methodology for a three-roadway, "T"-shaped, intersection is similar.

  • Patent number: 5682635
    Abstract: A reinforced precast construction includes a generally panel-shaped reinforced concrete structural unit having a relatively flat upper surface adapted to support vehicles thereon and opposing ends configured to be positioned in abutting end-to-end contact and in abutting side-to-side contact. One of the opposing ends includes a horizontally extending gasket so that, when abutted against an adjacent identical article in an elongated arrangement, the abutting opposing ends sealingly engage the seal. Connectors are attached to the structural unit in positions so that they align and are interconnectable with fasteners to hold the structural unit to an adjacent previously laid structural unit. In one form, the precast structural units are adapted to rest on parallel beams to form a bridge construction, and include locators for locating the precast structural units horizontally on the beams.
