The NITI Aayog has approved several high-tech mass rapid transport proposals to improve public transport. Consider the following aboutthem.

1.Hyperloop is a high air pressure tube connecting cities at speeds matching that of an aircraft.
2.Freight rail roads will be elevated corridors with rail lines where freight trucks can move on rails at high speed.
3.Pod taxis are underground transit systems that run entirely on solar power.
4.Hybrid electric buses combine a conventional internal combustion engine with an electric propulsion system.

Select the correct answer using the codes below.

This proposal includes high-tech mass rapid transportation technologies such as metrino, hyperloop, pod taxis, stadler buses, hybrid buses and freight rail road.

Statement 1: They are near-vacuum tubes so that air friction in travel can be

reduced. Statement 2: A dedicated corridor allows for greater efficiency and

speed.

Statement 3: These are usually cabled taxis running on an elevated drive train.

Statement 4: The addition of a battery-powered electric motor increases the fuel efficiency of hybrids in a number ofways.

Idle-off feature turns off the car's conventional engine when the vehicle is stopped, saving fuel.

The battery provides energy for the air conditioner and accessories while the vehicle idles at stoplights or in traffic, and the electric motor can start the vehicle moving again.

If needed, the conventional engine will reengage to provide more power for acceleration.

Learning: "Regenerative braking" is another fuel-saving feature. Conventional cars rely entirely on friction brakes to slow down, dissipating the vehicle's kinetic energy as heat.

Regenerative braking allows some of that energy to be captured, turned into electricity, and stored in the batteries.

This stored electricity can later be used to run the motor and accelerate the vehicle.
