曾有专家算了一笔账:目前北京至少有30%的交通时间在堵塞、在等待,有30%的车辆耗油是浪费,有30%的行路里程是多走的。堵车已经成为北京人的切肤之痛。当我们从“堵车”这个北京生活当中最烦人的问题出发,寻求问题的根本原因、解决途径时,我们遭遇了类似于“旧城改造”的新难题。 At one time, experts had calculated that at present, at least 30% of traffic time in Beijing is getting blocked. While waiting for 30% of vehicles to consume fuel, it is a waste of 30% of mileage. Traffic jam has become Peking Man’s skin pain. When we look at the most annoying problem of life in Beijing and find the root cause and solution to the problem, we have encountered new problems similar to the “transformation of the old city.”
