Research On Several Aspects For The Statistical Work Of Highway Transportation Volume In HeilongJiang Province

The paper depends on Heilongjiang Province transport department science and technology project"Heilongjiang Province region highway transportation volume survey and statistical method research". The papers mainly devoted to some problems in the study of the highway volume statistical work of Heilongjiang Province.Transportation volume is the fundamental datum for the statistics of highway transportation and playing a significant role in the management of highway transportation and relevant policy decisions. In the rapid development modern society, as the numbers of automobile increase day after day and more and more highways are constructed, it is inevitable that certain insufficiency and shortcomings can have in the statistic work of highway transportation volume. For example statistical report of Heilongjiang Province in 2003 business transportation volume, referring to the difficulties encountered in the volume of highway transportation statistics, while proposed the corresponding solutions. This paper tries to reduce the difficulty in the statistical highway transportation volume, found the suitable method of statistics highway transportation volume. In order to better understand and ma- ster the Heilongjiang highway transportation volume statistics work well, the scientific research group investigate to Heilongjiang Province. Information obtains through the investigation and study, emphasis analyzes several aspects of the Heilongjiang Province highway transportation volume statistics work, on the basis of summarizes and induction defects which exists in the highway transportation volume statistics work, proposes the safeguard measure of highway transportation volume statistics work. Statistics on the volume of highway transportation, proposed to use postst- ratification random sample method in the district level and has carried on simulation and explanations. Has studied stratification criteria carefully in the sampling method, proposes two definite stratification criteria approach, First, according to carrying capacity of the automobile make certain stratification criteria; Second, according to the theory of Delenius and Hodges, proposes the method of optimized stratification criteria, and has carried on verification. This paper is divided into five chapters, Chapter II, Chapter III and IV is the key text.The first chapter of paper is an introduction. Mainly elaborated important role of the highway transportation, research background of the paper, significance of research and the current development of several aspects of highway transportation volume statistics work in domestic and overseas.On the basis of really investigates and studies in Heilongjiang Province, has analyzed on some aspects of the Heilongjiang Province highway transportation volume statistics work, summarized questions in the region highway transportation volume statistics work existed which in the material the available information, proposes the safeguard measure highway transportation volume statistics work. in second chapter of paper.The third chapter of paper is focusing on the study of highway traffic statistics. the paper uses the current methods commonly"sampling method". Has analyzed commonly used sampling method, compared with commonly used sampling method characteristic; proposed the sampling method"poststratification random sample method", and carries on validate in Heilongjiang.The paper fourth chapter research in stratification criteria in the sampling method, proposed to improve stratification criteria and optimization stratification criteria for policy-makers to choose, and explained each one suitable situation, carries on the simulation. Improved stratification criteria according to the current automobile models change is concrete the numbers of passenger seats change because of the specific terms in the latest releases which are presented and the country has made the newest adjustment in the load quality of vehicles made in the latest regulation, Optimized stratification criteria is enables the statistics result to achieve the best income effect. The principle of optimization stratification is used Delenius and Hodges's speediness close to each other, achieved the best sampling benefit in the stratification, the optimized stratification criteria method also may apply in the appraisal the stratification criteria has marked.The fifth chapter of paper is a summary of papers and prospect of research paper, has analyzed the main achievement and the insufficiency which in the paper, needs further to study and the discussion question.The paper embarks from the perspective of statistical works that highway transportation management, provide the accurate statistical data for planning and decision-making to ponder the question and solves the problem, Proposed safeguard measures of highway transportation volume statistics and appropriate method of in highway transportation statistics to validate, Proposed two stratification criterias definite method in the sampling method for the policy-maker.The research of paper on highway transportation statistics has laid the foundation for following research.
