Title: Relativity Analysis on Traffic Accident and Precipitation of Jingjintang Expressway in G2
Abstract: The paper analyzes the data of Jingjintang expressway in G2 from March 2007 to February 2010,including the daily changes of the traffic accident on millions vehicles,traffic volume and meteorological elements.It further explores the relativity between traffic accident on millions vehicles(the number of traffic accidents/traffic volume) and the synchronous precipitation.The results show that the million traffic accidents peak of in one day appeared at 5 o'clock,and the average peak is up to 234 times in millions of vehicles.For year,spring,summer,autumn and winter,the average precipitation and synchronization million traffic accidents are observed to be the positive second-degree parabola relation,namely,the number of one million traffic accidents rises with the precipitation increase.The statistical test also shows good relativity by(RRα= 0.01 and F Fα = 0.01).The precipitation coefficient of 0.738 6 to 0.863 5 indicates that four seasons million traffic accidents associated with the precipitation.The results provide reference for safety management of the Jingjintang expressway in G2.
