上海市第五次综合交通调查综合校核技术

居民出行调查主要依赖人工实施完成,受到各种人为因素制约,容易导致调查结果在反映真实出行特征方面存在偏差.因此,需要进一步利用和分析综合交通调查和其他相关数据进行综合校核.以上海市第五次综合交通调查为例,提出人员出行特征和车辆出行特征综合校核的技术方法.利用交通行业相关统计指标、交通大数据、其他专项调查以及交通模型对出行特征指标进行比对校核.重点阐述人员、客车、货车出行特征校核的方法及步骤.最后指出,与以往调查校核相比,本次校核大量应用信息化数据,有效地将传统调查与信息化调查成果相融合.

Data Verification of the 5th Shanghai Comprehensive Transportation Survey

Because of the human factors in manually conducted household travel survey, there are often gaps between the survey results and real travel characteristics. Therefore, it is necessary to verify/rectify the data from comprehensive transportation survey with other relevant information. Taking the 5th Shang-hai comprehensive transportation survey as an example, this paper proposes a comprehensive verification technique for individual and vehicle travel characteristics, that is, to take advantage of available statistical indexes from transportation industry, transportation big data, other specific surveys and transportation mod-els for comparing and rectifying the travel characteristics. Techniques of travel characteristics verification for person, passenger car, and freight vehicles are elaborated. Finally, the paper points out that compared with existed survey data verification methods, the new verification techniques effectively integrate tradi-tional survey and informatization survey results using mass informatization data.
