城市市民出行难的问题已经变得越来越突出。造成这种尴尬局面的一个重要原因,便是自行车的生存环境越来越差,尤其是随着我国汽车产业的大发展以及汽车进入寻常百姓家,自行车的生存空间日益受到严重挤压。有数据显示,北京2009年的自行车出行比例只有19.7%,这不免让人忧心忡忡。 The problem of hard travel for urban citizens has become more and more prominent. An important reason for this embarrassing situation is that the living environment of bicycles is getting worse and worse. Especially with the great development of China’s automobile industry and the entrance of ordinary people into homes, the living space of bicycles is increasingly severely squeezed. Data show that Beijing’s bicycle traffic in 2009 was only 19.7%, which can not help but make you worried.
