The Study Of Theories And Practice In Urban Residents Travel Survey

Travel survey of urban residents for the survey of urban residents are the residents Ends travel distribution, travel purposes, travel time, trip distance, travel intensity, mode and parking, etc. for data acquisition, collation and analysis of the research work, is the urban transport development strategy, integrated transport planning and other special transportation planning and an important foundation for research work. Since the last century,80major cities in China since the introduction of residents of the western developed countries travel survey of existing theory to practice, to obtain a large number of urban travel behavior characteristics of the research results, for the then Urban Transportation-related decisions in the scientific, made important contributions to standardization. However, with the practice of in-depth survey of urban residents, both theory and the contradictions between China’s national conditions have gradually apparent. In the current city and the rapid development of urban transport situation, urgent need to adapt to the establishment and improvement of urban characteristics in travel survey of residents in the theory and practice.Characteristics of urban travel demand and transport supply and demand balance of the mechanism and direction of future evolution of urban travel is an important issue in survey research. In this paper, the traffic demand analysis and demonstrate the randomness and regularity, reality and potential, time and spatial specificity of the theory of imperfect substitutability, based on the strength of the permanent residents of trip purpose, temporal and spatial distribution and mode selection rules, travel on temporary residents of low intensity, small-scale, end sociability, and the mobility and seasonal, as the representative of the various types of tourist destination travel behavior characteristics of the floating population analysis carried out for objective control of urban traffic demand characteristics and laws of the foundation.Sampling rate of urban travel survey design is the key technical aspects of design, but also the difficulties on the theory and practice. In this paper, based on statistical sampling theory, sampling methods in analyzing the characteristics and selection factors under the premise of pre-enriched the investigation (or pre-sample) statistical significance, and according to statistics of the two-stage stratified sampling theory, the travel survey of residents in land-based pre-entropy sampling stratified two-stage stratified sampling method and the optimal sample size allocation.Urban travel survey data very large, very complex data structure, usually a dedicated database system should be established to store and applications. Based on the analysis and research on the basis of the general database system, the residents described the general travel survey database design, security, modular, intelligent design, and data collation, analysis, the general process of functional requirements. Travel survey with residents in the actual work on the database preparation, data entry and data collation and review stages of important issues and solutions related to, and database design software selection, data dictionary design, database design and interface design issues analyzed and discussed.Urban travel survey travel behavior of residents in the use of a sample of random process to infer the general characteristics of urban transport demand, has long been a travel survey of residents in the most difficult. In this paper, Xi’an resident travel survey in2008actual data, the direct expansion of the data sample, check sample expansion, the model parameter calibration and integrated method of adjusting the study started. Proposed based on multi-source data integration, combined with residents travel survey, special supplementary surveys and statistical data points passenger data sources, sub-objects, sub-three-step approach (comprehensive expansion of samples and synthesis of single-factor calibration adjustment) analysis methods, and relevant specific model. And group-like spatial structure and form for the city area was proposed based on OD data verification check model and study the corresponding calculation.
