城市交通犹如人身的血液系统,血液通过血管往返循环,维持着人的生命,因此血管不能堵塞。城市交通也要求畅通无阻,否则会阻碍城市的正常运转。小区交通则不同,它是城市交通的延伸,然而又是城市交通的末梢。血液流到手、脚和头颅等终端后要流回来,而不是穿过去。所以小区交通空间的处理应不同于城市的交通空间。 Urban traffic is like a person’s blood system. Blood circulates through blood vessels and maintains human life. Therefore, blood vessels can not be blocked. Urban traffic also requires unimpeded access, otherwise it will hinder the city’s normal operation. Community traffic is different, it is an extension of urban transport, but also the end of urban transport. Blood flow to the hands, feet and skull and other terminals to flow back, rather than through to go. Therefore, the handling of residential traffic space should be different from the urban traffic space.
