But to our surprise, more advanced transportation incurs more crowded and unsatisfied traffic instead of clear and convenient traffic. City congestion is a huge waste of time, energy and human potential. And we can hardly do anything about it. For decades, our solutions to traffic congestion in cities were simple: build new roads or enlarge existing ones. But it worked less than we expected. In more established metropolises, significant network expansions are almost impossible. However, the speaker got inspirations when he talked to one of his clients with biological background. All blood veins and arteries can be regarded as complicated transportation of heavy traffic in our body. He realized that biology has been in the transportation business for billions of years which could have put countless methods to transform elements in our body. So, the question is why there are so much traffic jam while our blood keeps flowing all the time? In fact, they are two obviously different from each other. All veins and arteries of each person could be 60,000 miles in length, but they are based in three dimensions as opposed to our traffic system in two dimensions. Maybe most people argue that we have planes, subways and some other ways, but it is clear that the majority of traffic is land transportation at present, which just occupies the ground. Thus, we need to elevate our traffic to a little higher level. Imagine about the convenience that some newly-invented vehicles like flying taxis or magnetic tramcars with suspended tracks. Another method we can take is to create a mass-transit system to replace the contemporary traffic system.
