G2京津塘高速公路万辆车流的交通事故灾害与气象综合指数的关系
The Traffic Accidents of Huabei Freeway and its Relation to the Meteorological Composite Index
摘要
Abstract
Based on investigation of traffic accidents, traffic flow and meteorological factors data of Huabei Freeway from Mar. 2007 to Feb. 2010, the diurnal variation of traffic accidents is presented at 5 am, and the peak of annul average could reach to 2. 34 times. The correlation between the traffic accidents among one million of traffic flow and the same period of the meteorological composite index during annul, spring, summer, autumn and winter present parabola, and the correlation coefficients account for 0. 778 1 to 0. 853 7 , satisfy statistics verifying (R >Ra=0.05 and F> Fa=0.05). In order to better use the meteorological monitoring information and to improve the safety of freeway, the meteorological composite risk level index is designed for supplying scientific grounds.关键词
