基于二级优化的OD需求反推模式的应用研究

准确的OD需求数据能提高交通规划的精度,因此,交通规划中重要的一环就是得到准确的OD需求数据.将二级优化的OD需求反推方法应用到真实的规划数据上,分析结果数据,验证二级优化方法的有效性.结果表明,使用二级优化方法反推OD需求时,反推的结果与实际流量的拟合度很高,误差也很小,能够满足交通规划对需求数据的要求.

A land use and transportation integration method for land use allocation and transportation strategies in China

In this paper, we will first review literature of the land use and transportation interaction and then develop a new land use allocation methodology called Three Stages-Two-Feedback Method (Integration Method) for both land use allocation and the transportation policy options with a practical implementation. Then we apply this method in an urban general planning project in China with more than 1.2 million populations. In this project, we evaluated three land use allocation strategies and three transportation policy options using two application tools (with and without feedbacks) using this method implemented in a land use planning system UPlan and a transportation planning system Emme. The results show that the use of the feedback method (Application Two) results in a vehicle distance reduction and the increase in the service coverage area of transit bus stops at the same time. Due to the use of transportation accessibility and the congestion measures with a MSA implementation, the accessibility measure shows a convergent process over iterations. This nice feature can be used for alternative comparisons. Future research subjects are also discussed.     

Emme在公路内外交通衔接规划中的应用

在我国经济社会发展进程中,构建并完善功能强大的综合交通运输系统势在必行.区域公路网和城市道路网在综合交通运输系统中地位举足轻重.两者衔接之处的内外交通衔接路网承担着区域和城市的内外交通需求,是决定两个不同运输网络联系、转换效率的关键节点,解决内外交通衔接问题十分迫切.通过温州市区规划实例来讨论和展现Emme软件在内外交通衔接规划中的应用,从需求与供给的角度对衔接路网进行交通系统分析,并基于交通和土地利用互动对多方案进行比选优化.
