在分析目前交通影响分析范围确定方法不足的基础上,提出了基于场理论的交通影响分析范围确定方法。该方法以物理学的场理论为研究工具,把开发项目对周围交通产生的影响类比为一个效应场,探讨效应场作用范围大小的主要影响因素,并建立开发项目效应场的场势模型,提出根据场势分布情况确定交通影响分析范围。算例表明该方法不仅可以通过场势分布了解开发项目对周围影响大小,而且可以较为方便的确定交通影响分析范围。 Based on the analysis of the shortage of methods to determine the scope of traffic impact analysis, a method to determine the scope of traffic impact analysis based on field theory is proposed. The method uses the field theory of physics as a research tool, and analogies the impact of development projects on the surrounding traffic as an effect field, discusses the main influencing factors of the scope of the effect field, and establishes the situation model of the effect field of the development project. Determine the scope of traffic impact analysis according to the situation distribution. The example shows that this method not only can know the impact of development project on the surrounding area through the distribution of the situation, but also can easily determine the scope of traffic impact analysis.
