China's high speed of development has also brought challenges for its urbanization drive. Pollution and traffic jams are just two. But new technologies are redefining future transport. In today's special series Beyond the Wall, CGTN correspondent Han Bin talks with two designers, whose ground-breaking visions and practice, may bring a revolutionary change for the cities of the future.

The engine of progress has brought traffic jams to most cities in China. Many agree urban transport needs a new direction.

WU GANSHA, FOUNDER UISEE TECHNOLOGY "UISEE, UISEE, stands for utilization, indiscrimination, safety, efficiency and environmental friendliness. This is one of our biggest R&D sites. You see a lot of testing cars with different kinds of sensors. We are testing this camera, this is what is supposed to see, and this is what is supposed to perceive. And what you can see here, is a simulation environment. And this is how it perceives this environment. To completely reduce the traffic jams, we need a systematic approach. We need to reduce the number of vehicles through car sharing, each vehicle needs to be intelligent. We need smart city brain, so that all the vehicles are scheduled based on a global and optimized plan. This is based on the fact that the cars are self-driving."

Other designs are reshaping traditional road building concepts into a three-dimensional future.

The concept of a flying car is not new. But this module uses vertical take-off and landing, meaning it can be used anywhere.

WU GANSHA, FOUNDER UISEE TECHNOLOGY "We focus more on the interaction, instead of the manipulative control. So It has all the sensors surrounding this car. You can do anything in a car, you are living in this space. China needs this new technology badly. China's auto industry has been a follower, but now, because the technology is revolutionary, we can leave behind all the legacies, and overtake on a corner."

Chinese scientists say it's more than just creating new cars. The only limit is the human mind. With policy incentives, all this science fiction of the past could redefine the future of transport in China. The expectations are high. The question is: How long it will take to make it happen?

So, they are pushing the boundaries a step further.

WU GANSHA, FOUNDER UISEE TECHNOLOGY "We see quite a few barriers today."

WU GANSHA, FOUNDER UISEE TECHNOLOGY "Then, the technology maturity."

WU GANSHA, FOUNDER UISEE TECHNOLOGY "Then, the cost of the solutions."

China has arrived at a crossroads. Where to go next—and how to get there?

HAN BIN UISEE, BEIJING "Many companies, just like UISEE, are already working for a future, in which new technology will reduce traffic jams and increase road safety. A lot of visions are still in the experimental phase, but they are shaping the future of mobility far beyond highways and express trains. Han Bin, CGTN, Beijing."
