  • This invention relates to a road structure for reducing pollution emitted by moving vehicles on the road.

  • the vehicle engines mostly internal combustion engines, have low thermal efficiency, by and large well below 50%. The large number of vehicles on the road, each generating its own energy requirement at low efficiency, leads to considerable loss of energy producing material such as petroleum fuel. Also the net pollutant emission is high.
  • Battery operated electric vehicles do not pollute the environment. But battery operated vehicles require frequent recharging with operating distance on a single charge being limited to about 150 KM. Also recharge time during which the vehicle is in a stationary state is long. Further, batteries are heavy and increases the overall vehicular weight and energy consumption. Therefore with the present state of battery technology battery operated vehicles are in limited usage and do not overcome the pollution problem.
  • an object of the present invention is to provide a road structure for reducing pollution emitted by the moving vehicles on roads and thus to avoid the disadvantages associated with the prior art.
  • Another object of the present invention is to provide a road structure for reducing overall demand of energy generating fuels and thereby the net pollution emissions from vehicles on the road.
  • Yet another object of the present invention is to provide a road structure having means to transfer energy from electrical power lines to the vehicle in mechanical energy form.
  • Still another object of the present invention is to provide a road structure which leads to conversion of the potential energy stored in the vehicle to kinetic energy thereby propelling the vehicle.
  • a further object of the present invention is to provide a road structure which transfers energy from electrical power lines to the vehicle in mechanical kinetic energy form by a vehicle tow system to eliminate / reduce petroleum fuel demand by the vehicle engine and therefore eliminating / reducing pollution generated by moving vehicles on a normal road structure.

  • the segment of up slope [6] follows the entry segment [5].
  • the segment [1] following intersection [10] and segment [5] following intersection [9] too have a very low up slope gradient.
  • the segment [2] and segment [6] have a high up slope gradient.
  • the energy requirement of a vehicle as well as the pollution emission is markedly reduced when moving down a slope as compared to when moving on horizontal ground.
  • the downward slope road structure segment [3] and segment [7] serve to achieve such a reduction in vehicular energy requirement. That is the vehicle when at the top of an elevated segment has high potential energy. When coming down slope the potential energy is converted to kinetic energy by the gravitational forces of the earth. The kinetic energy thus realized propels the vehicle forward without drawing upon energy from the vehicle engine. In this situation the vehicle engine will be in low power generation mode consuming low amount of fuel and in turn the pollution emission is also low. For the purpose of reducing energy consumption and pollution by means of a down slope the vehicle is to go up slope first.

  • a sleeve-rigid part [32] alternates with sleeve - flexible part [33].
  • Figure 4 shows one sleeve-rigid part [32].
  • each vehicle is fitted with a rod [35] which can be manipulated from the vehicle driver seat.

  • the driver On disengaging the clamp [36] from the hook [41] the driver can overtake a vehicle ahead on the vehicle engine power. Then getting onto a lane again the driver can activate the clamp to grip a hook on a sleeve - rigid part.

  • the energy provided to each vehicle may be quantitated and the vehicle owner charged in pre-paid or postpaid mode.
  • the movement of the vehicle is done with the rod being fixed to a rear member of the vehicle chassis and a sleeve on the rope like structure pulling the rear section of the vehicle forward.
  • the vehicle is pushed forward instead of being pulled forward.
  • a travelling magnetic field may be established under the road surface which is to drag a magnetic material or a proper magnet fixed to the vehicle.

All such vehicle have a brake on the central front wheel for emergency purpose besides the regular brake on the rear wheels. The front wheel brake is independent of the rear wheel brakes.
  • the three wheeler vehicle For deriving energy from the rope like structure first the three wheeler vehicle needs to come over the rope like structure with the central front wheel positioned over either the sleeve - rigid part [32] or over the sleeve - flexible part [33] or straddling a part of one sleeve - rigid part and a sleeve - flexible part. Thereafter the central front wheel brake is to be applied. The sleeve then drags the front wheel forward and thereby the whole three wheeler vehicle is propelled forward even if the vehicle engine is turned off or put on idle mode. No special fixtures to the three wheeler vehicle is required for deriving assistance from the rope like structure.
