基于综合交通调查多源数据的公交OD更新方法

Bus OD Updating Based on Multi-source Data of Comprehensive Transportation Survey

在上海市第6次综合交通大调查多源数据的基础上,研究一种基于公交线路客运量数据、居民出行调查数据、公交卡刷卡数据、跟车调查数据和轨道接驳方式结构数据的OD更新方法。首先,以居民出行调查为基础,通过校核、扩样处理,采用传统的“四阶段法”结合历史年份的公交模型得到新一轮大调查下的公交出行OD;其次,通过线路客流数据和刷卡上客数据反推全市道路上的断面量,并以公交断面量、线路客运量为依据调整公交OD,小区层面结构依据居民出行调查小区OD分布结构加以补充;最后,通过线路层面、跟车调查、出行距离时耗和总体特征指标的校核,证实分配结果达到宏观应用要求。

Based on the multi-source data of the sixth comprehensive transportation survey in Shanghai,this paper studies an OD updating method based on the data of bus line passenger volume,resident travel survey,bus card swipe data,car following survey data and rail connection mode structure data.Firstly,based on the resident trip survey,through checking and expanding sample processing,the traditional"four stage method"combined with the historical year bus model is used to get the bus trip OD under the new round of survey.Secondly,based on the data of line passenger flow and card loading,the cross-section volume of the city's roads is deduced,and the OD of the community is adjusted according to the cross-section volume of public transport and line passenger flow.The community level structure is supplemented by the OD distribution structure of the community according to the resident travel survey.Finally,through the line level,car following survey,travel distance time consumption and overall characteristic index verification,it is confirmed that the allocation results meet the macro application requirements.
