交通规划4阶段法建模及应用分析

Four-step Modeling Process and Application Analysis of Transportation Planning

交通规划分析是辅助城市规划者制定初步交通建设规划方案的一个重要参考,是城市区域交通建设规划的重要一环。但是,影响交通规划的因素很多,且各因素之间相互关联。为了确定其中的主导因素,需采用合理的方法对交通规划进行数据建模分析。利用4阶段法对指定区域内的交通需求产生量和选择趋势建模并实现量化分析,同时通过仿真的数据集合检验和分析所建模型的可行性。该分析结果可以在讨论制定交通规划方案时,对可能出现的各种交通现象和变化提供数据支撑和给出预测结果,同时可以检验交通规划方案的有效性和可靠性。

Transportation planning analysis is a critical reference for the city infrastructure planners to make out the primary transportation construction planning scheme,which is a critical phase of city infrastructure construction. There are a lot of factors affecting the transportation planning and they interrelate. In order to find out the major factors,a reasonable model should be needed to make a modeling analysis. By using four-step modeling,the transportation demand and selection trend of the appointed area transportation is modeled and the quantitative analysis is realized,and the feasibility of the model is verified and analyzed through the simulated data muster. The analysis results can provide the data support and give the prediction results for the possible transportation phenomena and changes when discussing and making out the transportation planning scheme,at the same time they can validate the effectiveness and reliability of the transportation planning scheme.
