【摘要】 通过对现有交通影响评价进行深入分析,结合北京市交通需求和交通评价的实际情况,提出了"两度一比一参照"的交通影响评价标准,即采用负荷冲击度、冲突复杂度、公交综合运能和项目合意度4个指标,从交叉口负荷、交通组织、公共交通和交通影响环境4个方面对建设项目产生的交通影响进行综合评价分析.根据以往工作的实践经验和结论,将以上指标模型化,并根据定量化结果对指标进行了分级,按照不同的分级结果判定项目是否通过、待改进或不通过.该项研究成果有助于北京市交通影响评价的定量化,并可以大大提高评价标准的应用性和可操作性.更多还原

【Abstract】 Based on extensive study of the traffic demand and actual situation of traffic impact analysis in Beijing,this paper proposes the evaluation criterion for traffic impact study.Four evaluation indicators are involved,which include variation of V/C ratio,complexity of conflict,capacity index of transit,and satisfactory degree of the public to projects.It implies that the traffic impact from project construction should be examined in terms of V/C ratio at intersections,traffic organization,public transit,and traffic conditions.With practical operations,the evaluation criterions are modeled and classified according to quantificational results.The impacts from projects are evaluated and defined to be passed,improvement needed,and rejected.The study provides applicable evaluation criterion for the quantificational traffic impact analysis in Beijing.更多还原
