Abstract:To study the influence of traffic access level and traffic control in on novel coronavirus （ SARS-COV-2 ） transmission Henan Province， taking COVID-19 as the research object of epidemic transmission， the spatial distribution of cumulative cases before and after traffic control was analyzed； the traffic access level of each county and city by using indicators such as highway， railway density， number of air-stop cities， and distance to Wuhan was calculated ； the spatial differences in the impact of traffic access levels on the spread of new coronaviruses were explored by means of geographically weighted regression analysis. The results showed that：（1） the confirmed cases were concentrated in the south and scattered in the north. However， in the north， Zhengzhou and Luoyang were the centers of high-value areas， while Nanyang and Xinyang in the South were formed isolated high-value areas；（2） traffic control had further strengthened the concentration of confirmed cases from the counties and towns under their jurisdiction to the municipal districts；（3） the higher traffic access level accelerated the spread of the virus， the high-impact areas were concentrated in the" L" type range of Zhengzhou City-Nanyang City-Xinyang City， however， after taking strong traffic control， Shangqiu City’s influence has dropped significantly；（4）although the distance factor aggravated the virus transmission in Nanyang and Xin- yang， the overall transmission trend was still affected by the traffic access level.
