Study On Sampling Technique And Data Analysis Of Urban Resident Trip Survey

Resident trip survey will get the trip characteristics (such as trip frequency, trip purpose, trip mode, trip time, trip origin and destination points, etc.),family property,personal property of a certain proportion of the population in the survey region one day, which grasps the dates such as the total urban traffic travel,the mainly trip generation and attraction source,temporal and spatial distribution,trip mode usage,etc. Resident trip survey is an important content of OD survey in traffic planning, which provides basic traffic data for the traffic demand forecast and the development of transportation planning programs plays an important role in urban integrated transport planning and management.Resident trip survey need takes huge human, material and financial resources, but also includes many links, from the preliminary design, publicity, training of investigators to the late implementation of the survey, data processing, every aspect will affect the whole quality, which requires implementation of the unit to fully consider every aspect of the relevant factors. This paper will research sampling technique and data processing, aims at improvement of existing methods and improves the resident trip survey technique.Firstly, on the base of used sample survey methods and the special permit of resident trip survey, this paper proposes the Optimal Two-Phase Equidistant Sampling, shows the optimal model based on principles of mathematical statistics and cost functions, further explores the hierarchical sign and hierarchical number. Then studying determined principles and investigation objectives of resident trip survey, this paper carries out design the sampling rate based on the requirement of survey data accuracy, inducts sensitivity analysis to reduce the risk of error. Following by the results analysis of resident trip survey data, this paper obtains data features and analysis. Combined features of Access database this paper sets up in Xining City resident trip survey data management system and corresponds expansion of the original data analysis and calibration sample. Finally, the sampling techniques and data analysis methods are used in Xining City resident trip survey practice, achieves good results.
