北京建国门立交交通分析及改造评价研究

Study on Traffic Analysis and Reconstruction Evaluation of Beijing Jianguomen Interchange

提以建国门立交改造为例,从系统角度对建国门立交及周边交通运行状态、交通拥堵分布及成因进行详细分析,分析结论为建国门立交改造方案的提出提供技术支持,并采用宏观模型和微观仿真两种方法对立交改造方案进行评价,确保在综合考虑周边现有交通设施与各类限制条件下,改造后的建国门立交具有安全、有序、畅达和舒适的交通环境。

Taking the reconstruction of Jianguomen Interchange as an example,the article systematically analyzes the traffic status,the distribution and the causes of traffic jam of Jianguomen Interchange and the surrounding in detail.The analysis conclusion provides the technical support to the reconstruction scheme of Jianguomen Interchange.Two methods of macroscopic model and microcosmic simulation are used to evaluate the interchange reconstruction scheme,and ensure that the reconstructed Jianguomen Interchange is under the safe,orderly,accessible and comfortable traffic environment by comprehensively considering the existing traffic facilities and various limit conditions in the surrounding.
