Commuting is a designated period of commuting between the place of residence and the place of work or study, and transcends the boundaries of the community where you live. In the urban agglomeration, there is a certain connection between the central cities of some megacities and the surrounding new cities and satellite cities, and there is commuting traffic, which we call metropolitan area, and its essence is life circle or commuting circle.
With the progress of transportation technology, cities can expand to places that were impossible before. The establishment of suburbs also enables citizens to live far away from urban areas and commute to work. Many big cities have so-called commuting areas, or metropolitan areas. Such areas include many commuter cities. People live in commuting cities and work in the city center.
Definition of commuting traffic circle
It corresponds to the definition of "commuter traffic", that is, the circle with "commuter traffic" connection with the core city; According to the definition of Japan, more than 5% of local commuter traffic is with the core city, so this area can be included in the "commuter traffic circle" of the core city.
"One-hour traffic circle" is not equal to "one-hour commuting circle". For the sake of people's health and happiness, we should not advocate and encourage the endless extension of commuting traffic circle, and one-way travel should be controlled within 45 minutes as much as possible. This should be the initial intention of big cities and transportation planning.
This "initial intention" should be carried out in our reasonable layout arrangement of urban spatial form and functional allocation, and in all details such as transportation infrastructure layout, site selection and route selection, standards, connection and matching, operation organization and information service.
