青岛市大尺度海湾型空间结构的交通方式选择

Travel Mode Choice with the Large-scale Bay-Type City of Qingdao

为支撑青岛市多中心、海湾型大都市空间框架,必须选择合理的交通方式,拉近各个城市组团的时间距离。首先,分析了不同城市规模下出行距离、出行时耗的相对稳定性和各种交通方式适宜的城市空间尺度。然后,按照空间圈层发展特点和交通特征的差异性划分市域、都市区和中心城区三个交通圈层,分析各交通圈层空间与出行时耗的关系。最后,基于时空约束提出各圈层交通方式的需求和选择。

To support the multi-center,bay-type metropolis of Qingdao,it is necessary to provide a suitable travel mode in order to cut down the travel time among the cities cluster.The paper first analyzes the varying travel distance,the comparable travel time and the suitable travel modes with different city sizes.Then it categorizes three types of urban transportation hierarchy,i.e.suburban area,urban areas and downtown area,according to the development status and differentiated travel demand characteristics,and analyzes the relationship between space and travel time in each hierarchy.Finally the paper puts forward the travel modes suitable for each transportation hierarchy that is subject to space-time constraints.
