交通影响评价(Traffic Impact Evaluation,简称TIE),或称交通影响分析,是对土地开发项目与交通需求增长之间的关系进行研究,分析项目对城市交通的影响范围和影响程度,从而确定相应的对策或修改方案,实施补偿政策,以减小开发方案对交通的影响。通过交通影响评价可论证项目开发或改动的可行性、协调用地开发与交通发展的关系、保证社会资源分配的公平性、倡导土地利用规划与城市交通规划的整合,避免产生交通供求不平衡,引发交通拥堵加剧、交通事故增多、城市环境恶化、增加能源消耗等问题。我国交通影响评价起步较晚,吸收发达国家既有交通影响评价研究成果及制度建设经验,结合我国城市经济社会发展需求及交通供给需求特征,形成交通影响评价制度,以 Traffic Impact Evaluation (TIE), or traffic impact analysis, is a study of the relationship between land development projects and traffic demand growth. It analyzes the impact range and impact of the project on urban traffic so as to determine the corresponding Countermeasures or amendments to the program, the implementation of compensation policies to reduce the impact of development programs on traffic. Through the traffic impact assessment, the feasibility of project development or modification can be justified, the relationship between land development and traffic development can be coordinated, the fairness of social resource allocation can be ensured, the integration of land use planning and urban transport planning can be advocated, unbalance of traffic supply and demand can be avoided, Increased traffic congestion, increased traffic accidents, deteriorating urban environment and increased energy consumption. The traffic impact assessment in our country started relatively late. It absorbs the research achievements and system construction experience of the existing traffic impact assessment in developed countries. Based on the demand of urban economic and social development in our country and the characteristics of traffic supply demand, a traffic impact assessment system
