A freeway interchange system designed by college student, Li Xu, has moved one step closer to being awarded a government patent. The student from Harbin Institute of Technology in Northeast China takes aim at reducing the severe traffic congestion in Beijing with his plan.

His inspiration came from a business contract his father lost 6 years ago because of a traffic jam. Encouraged by his father, Li chose urban planning in college, and endeavored to make improvements on the traffic situation in the capital.
