The Study Of Highway Traffic Statistics Method

Highway traffic statistics is a major part of the highway industry statistics on road transport industry which is an important component of socio-economic statistics part of the road transport industry to carry out an important tool for scientific management. The Highway traffic statistics is reflected in the transport industry which is an important indicator of the fruits of production, but also an important indicator to reflect national conditions. Acquisition access to traffic statistics and the country has always been transportation management department at all levels of attention, the volume of road transport at the transport industry output in the living center.With the gradual deepening of reform and opening up, China's increasing emphasis on the statistical work in decision-making role. In practice, however, the volume of China's road transport statistics investigate the existence of statistical goal was not clear, the statistical content of the system is weak, statistical techniques need to improve such defects, at the same time because of the volume of China's road transport survey lag, making the implementation of road transport planning there is a big subjectivity, blindness. In this paper, the socio-economic statistics and sampling theory is based on an analysis of t Highway traffic statistics in our country survey of the history and present situation of China's road transport volume survey of the problem exist; and automotive equipment in road transport volume investigate the use of carried out exploration and study, based on vehicle equipment, the volume of road transport investigate statistical methods, as the volume of the existing road transport investigate an effective complement to statistical methods; the last of China's road transport volume survey of non-sampling errors, the systematic study will investigate the volume of China's road transport statistics of non-sampling error is divided into three categories: sampling frame errors, no error and measurement error to answer, and the use of mathematical model of these three types of errors on the estimated traffic impact of the results of detailed studies, then put forward to control the three types of non-sampling error measures and methods.
