交通出行率是反映城市交通与土地利用相互关系的重要指标之一，是城市交通规划、建设项目交通影响分析等工作中定量分析交通需求和供给关系的基础。在一些发达国家如美国，对交通出行率指标进行了很多研究工作，并出版公布多版《Trip Generation》供全国交通工程师和相关专业人员参考。而北京市目前还没有任何对外公布的技术或部门标准来统一各类建筑的交通出行率指标值，这相当不利于开展各项交通定量分析和评价工作。本文在对北京市城区范围内办公建筑进行交通出行率调查的基础上，经过数据分析和处理，初步得到了北京市办公类建筑出行率指标的建议取值标准。

Research on Trip Generation Rate of Office Buildings in Beijing

Generally,trip generation rate(TGR) is one of the most important parameters that reflect the relationship of city land-use and transportation development.TGR is also the start point in the process of urban transport planning and traffic impact analysis(TIA),etc.In some developed countries such as USA,Some researches are conducted frequently and continuously to publish up-to-date version of Trip Generation},which give support to planners and engineers in their analysis work.But it is impossible in China for there is no standard of trip generation rate for any kinds of offices and that makes it difficult for reasonability and precise in many quantification works.The paper gives a set of trip generation rate for office buildings based on some surveys and analysis of trip generation of several office projects in Beijing.
