Model of Relation between Urban Transportation Development and Macroscopic Road Network Operation in Beijing

Based on the statistical analysis of Beijing urban transportation development level,we put forward the principle for selecting the indicators of urban transportation development level,created the comprehensive evaluation index system for urban transportation development level consisting 16 indexes in the aspects of social development,transportation supply and transportation demand,and established the evaluation index system for macroscopic road network operation based on road network congestion index(CI) and arterial network's peak-hour travel speed.By gathering and processing the statistical data of Beijing during 2003-2010,we identified the input indexes for the relation model,established the relation model between urban transportation development level and road network operation by using partial least square(PLS) method,and the relation model was validated by the available data.The validation result shows that the model's precision is within 10%,which can meet the need of actual use.The model can support the decision-making for Beijing's future urban transportation development and transportation development strategy.
