Research On Spatial Transport Linkage Of The Flow Of Highway Passenger In Henan Province

The transportation plays an important role in the social economic activities. Relying on regional transportation and its infrastructure, the exchange of passengers and goods promote inter-regional division and cooperation of labor, and affect regional economic growth and regional economic structure. Research on inter-regional transport links in space is able to reveal the interaction laws of space, the awareness of the regional opening degree and the direction, strength and characteristics of inter-regional links with each other.Construction of transport infrastructure in Henan Province is in a high-speed stage of development. How does the continuously improved transportation infrastructure influence inter-regional spatial transport linkages? How does it affect the spatial distribution and evolution of transport linkages? How does it change the inter-regional transport flows? Considering these problems, this article studied the spatial transport linkage of highway passenger in Henan province according to the spatial transport theories. In this paper, the regularities of formation, growth, distribution and exchange of highway passenger in Henan province are studied. The results revealed the characteristics of inter-regional linkages and the trend of spatial evolution.This paper integrates the attribute data and spatial data of transport linkages in Henan by ArcGIS software. In order to generate spatial transportation network diagram of Henan province, it uses AO+VBA to program on models in Arcmap with passenger transport O-D data and statistical data, and finally determine the pattern of spatial transport linkage of hignway passenger in Henan province.Using gravity model to Henan Province various counties (cities) the transportation relation potential energy carries on the potential analysis, by the comparison of the operation result and the passenger flows, it has analyzed the development of regional transport linkages, given priority to development the region of Henan Province highway passenger transportation.The conclusions are as follows:(1) Around the city of Henan Province, the highway passenger traffic level and the economic development level have an obvious positive correlation, but also has a little poor co-ordination.(2) The growth rate of Passenger Traffic and Turnover Volume is not consistent in the whole Henan City, but there is a big difference. Whole economy in Henan's increasing speed is quicker than passenger transportation level in the highway of growth speed.(3) In regard to the distribution proportions of Passenger Traffic and GDP, in Henan Province, Central part and the east have very different. The unbalanced coefficient shows around the city of Henan, the development of GDP tend to be more uneven. The unbalanced coefficient of population remains basically unchanged. The unbalanced coefficient of passenger traffic and turnover volume volatile from top to bottom, and it presents the change tendency consistent characteristic.(4) Usually, the prefecture-level cities are the primary linkage city of counties and cities which it rules over. As the provincial capital of Henan, Zhengzhou shows an obviously polarization effect. And its Radiation range covers over the whole province. Spatial attenuating tendency of highway Passenger Traffic in Henan province is very obvious. Passenger Traffic with the distance reduces very quickly. It explains that the short distance passenger traffic account for a large proportion.(5) In intensity model, the central part of Henan is the absolute links center. From the region internal relations, the northern part of Henan has the biggest Contact intensity. In gravity model, Zhengzhou's agglomeration effect is more obvious, compared to the status of Luoyang City declined in 2007. The node connection graph shows the connection of regional relationship has the characteristics of Hub-and-Spoke System.(6) Comparison of regional potential and the exchange of traffic, we can see that the two regions, from Jiyuan city to Zhoukou City and from Puyang City to Luoyang City, are priority development zone.(7) GIS tools for geo-spatial analysis have obvious advantages. It plays a strong supporting role in the calculation of indicators, the model selected, the results of the output, etc.
