We received a question from a Chinese listener living in Shanghai who had visited Japan. He was impressed by the convenience and efficiency of the Tokyo transportation system despite the vastness of the city. Reporter Duan Wenning is from China. She interviews a professor at the University of Tokyo who is a "Traffic Jamologist" and offers tips on how to deal with traffic congestion. She also introduces initiatives undertaken by transportation authorities to alleviate overcrowding, starting with the rush hour. Would you rather stand up for your commute or pay extra and use your time more effectively? Do you want to stay fit and healthy? Let's take a closer look at new modes of transportation in Tokyo, and hear some answers to these questions.
