雄安城际站、小里站交通预测及交通组织分析

Analysis on Traffic Prediction and Traffic Organization of Xiong'an Intercity Railway Station and Xiaoli Railway Station

摘要:

雄安新区作为北京非首都功能疏解集中承载地，必须完善其区域综合交通网络，构建新区便捷的交通体系。在上位规划和城市设计研究的基础上，构建了雄安城际站及小里站区域范围交通预测模型，采用人口高限进行测试。利用模型预测与交通流线布局的互馈结果，进一步应用预测模型对流线布局进行检验分析。研究结论为：在规划年限内，路网的建设规模适宜，能够支撑雄安城际站、小里站枢纽区域周边的交通需求；将东西轴及雄安城际站周边部分支路设置为单向交通，具有可实施性；对研究范围内地下环路的设计进行了交通组织优化，可有效缓解两车站间的地面道路交通压力。

Abstract:

As a distribution centralized bearing area of non-capital functions of Beijing, Xiong'an New Area is required to improve its regional integrated transportation network and build its convenient traffic system. On the basis of master planning and urban design study, the regional traffic prediction model of Xiong'an Intercity station and Xiaoli Station is built, and the population limit is adopted for testing. The prediction model is further applied to check and analyze the streamline layout by the mutual feedback results of model prediction and transportation streamline layout. The study conclusion shows that the suitable construction scale of road network can support the traffic demand around the hub area of Xiong'an Intercity Railway Station and Xiaoli Railway Station within the planning years. It can be implemented to set the east-west axis and some branch roads around the intercity station as one-way traffic. The design of underground ring roads within the study scope optimizes the traffic organization, which can effectively alleviate the traffic pressure of ground roads between two stations.
