Abstract
In order to study the sensitivity of road network capacity, building volume and car ownership to traffic congestion, the congestion index was put forward as the evaluation index of sensitivity. The east⁃ern district in Qingdao was divided into twelve medium-sized traffic zones according to the administra⁃tive division and the layout of urban functions. Relied on EMME4 software platform, based on the data of land use and road network, the present situation and development trend of road network capacity, build⁃ing volume and car ownership in each medium-sized traffic zone were subjected to statistical analysis and their inherent relations with congestion index were concluded. The corresponding change rate of con⁃gestion index under different conditions became clear after the incremental changes of single factor as well as different combination of factors were analyzed respectively. The study indicates that the sensitivi⁃ty to congestion increase gradually in the sequence of building volume increment, road network capacity increment, car ownership increment. Furthermore, the improvement effect of network congestion under combination of measures is better than single measure. The road traffic conditions will be effectively im⁃proved by controlling car and building volume increment, improving transport infrastructure and increas⁃ing road capacity.关键词
