Research on the construction and spatial pattern of the isochronous transporta-tion circle in the main urban area of Qingdao
The research took the traffic circle of the main urban area of Qingdao as the object,analyzed the traffic circle of the main urban area of Qingdao,and made up for the lack of relevant research.The main urban area of Qingdao was identified according to the land price equilibrium theory.Using kernel density analysis and central service area algorithm,supplemented by OD matrix anal-ysis and cost distance analysis,the isochronous traffic circle of Qingdao main city was generated.The traffic circle of Qingdao main urban area was divided into core area transition area and edge area,and its spatial pattern characteristics such as space range and cir-cle form were analyzed and evaluated.According to the analysis results,some concrete suggestions on traffic planning were put for-ward.The results showed that the average time cost based on function is 0.58 h in the main urban area of Qingdao,and the differ-ence of time cost in different regions was obvious,among which the core area had a high road network density,and the distribution was narrow and long.The transition area was around the core area,the road mileage was short,the network density was the lowest,and the spatial distribution pattern was irregular.The time cost in the edge zone was the highest,but the density of the road network was higher than that in the transition zone,and the spatial form was distributed in a group pattern.
