Final Design

From the 101 ideas of how to solve this problem, they are all being combined into one idea which is the best to solve ‘Traffic Jams’.

Wings for cars can be an effective way to avoid traffic jams. It will be placed on the two side of the car and it can be closed and open whenever it is needed. There are two wings which are for the left and right, and also  another one on the above.

This car also need a special road that we designed which is similar with the roller coaster track. The track has a connector that makes the wheel can connect and release to it. When the car is about to fly, there is a signal lamp on the car for the other car to know and avoid a car crash. The track itself, will have a long way for the car to be ready while take off.

Placement

The concept will be applied in the whole city where from building to building will be placed the tracks and it is similar to the highway on the road.

Pros and Cons

Pros and cons of the 4 chosen sketches

From the exercise of doing the pros and cons, I will be able to know which ideas is good and which one is not. It is important to do such things so that we know which ideas are better to be chosen for our final design.

Sketches of design

Here are our sketches of design that we have done. Basically, we got the ideas from the brainstorm of 101 ways to solve the problem. 

 Double Decker MRT

 City in the sky

 Roller coaster Track

 Underground Tunnel Road

Flying Cars

Flying Cars Inspiration

Basically, the inspiration of "flying cars" idea comes from the airplanes. It is how the airplane can fly in the sky by using a method of Bernoulli Principle. Then the thought just came, why didn't we apply the same way of how airplanes can fly to a car? Read more in this article that I took from a website:

How Airplanes work?

Every object on Earth has weight, a product of both gravity and mass. A Boeing 747-8 passenger airliner, for instance, has a maximum takeoff weight of 487.5 tons (442 metric tons), the force with which the weighty plane is drawn toward the Earth.

Weight's opposing force is lift, which holds an airplane in the air. This feat is accomplished through the use of a wing, also known as an airfoil. Like drag, lift can exist only in the presence of a moving fluid. It doesn't matter if the object is stationary and the fluid is moving (as with a kite on a windy day), or if the fluid is still and the object is moving through it (as with a soaring jet on a windless day). What really matters is the relative difference in speeds between the object and the fluid.

As for the actual mechanics of lift, the force occurs when a moving fluid is deflected by a solid object. The wing splits the airflow in two directions: up and over the wing and down along the underside of the wing.

The wing is shaped and tilted so that the air moving over it travels faster than the air moving underneath. When moving air flows over an object and encounters an obstacle (such as a bump or a sudden increase in wing angle), its path narrows and the flow speeds up as all the molecules rush though. Once past the obstacle, the path widens and the flow slows down again. If you've ever pinched a water hose, you've observed this very principle in action. By pinching the hose, you narrow the path of the fluid flow, which speeds up the molecules. Remove the pressure and the water flow returns to its previous state.

As air speeds up, its pressure drops. So the faster-moving air moving over the wing exerts less pressure on it than the slower air moving underneath the wing. The result is an upward push of lift. In the field of fluid dynamics, this is known as Bernoulli's principle.
