| [Objective]Analysis the city of Liuzhou road traffic injuries of data, understand Liuzhou road traffic injuries of popular situation, features and distribution laws, the thorough analysis road injuries between points, the space distribution features, to determine the injury the list of sections, explore its popular rule,for road traffic injury prevention, control and monitoring, and formulate intervention measures and decision making legislation to provide the scientific basis.[Methods] Collect2000～2009liuzhou city road traffic injuries material, establish liuzhou road traffic injuries database,application Excel2007road damage calculation of Incidence, Mortality rate, Injuries and Direct economic losses of Liuzhou describe the extent of the road traffic injuries and its change trend, and application SPSS17.0description of road traffic injuries linear, the intersection of the types of roads section type, the vehicle type, area and the weather in the distribution of road traffic injuries. Based on GIS space to the regression forecast traffic injuries, and at the same time, through the spatial autocorrelation analysis, using the weighted distance of ArcGIS interpolation method draw special map, describe the space distribution features of traffic injuries.[Results]①Liuzhou road injurues from2000to2003in the four indexes remain at high levels, began to decline since2003, to2005years to a minimum,2006～2009injured in accidents occur and a slight fluctuations, but direct economic losses and the death toll less volatility. Four city accident occur and injured more than number by the order of the YuFeng district LiuBei district, ChengZhong district LiuNan district; The death toll and direct economic losses to the order of the less by many for LiuBei district, YuFeng district, LiuNan district, ChengZhong district.①2000～2009liuzhou city road traffic injuries94%or more major concentration distribution terrain in the plains region, hilly area, except the proportion in2004and2005is higher,10.08%and14.29%, respectively, in the mountainous area happened10years of road traffic injuries accounted for about3%to the highest.2000～2009liuzhou city road traffic injuries before form six are:the side crashes, followed crashes, collided head-on, bump fixed things, to scratching and homonymous scratching, respectively38.95%,18.97%,14.08%,6.89%,6.69%and3.37%. Do injuries and driving experience level shows, F=96.84,P<0.001, driving and injuries level assumes the negative correlation.③The scene of the accident to the original state of proportion in ten years were higher,2006～2009years had down trend, and since2006, motor vehicle driver ditch the car happened to escape and driving the escaping the proportion accident significantly increased, about had16.98%in2009.10years were traffic injuries are statistically significant gender differences, t=427.88, p<0.001, age distribution to30to34years age group was highest injuries, professional situation:independent practitioners, transportation, agriculture, forestry, fishery, unemployed and peasant-worker, compared to26.19%,16.74%,10.75%,5.83%and3.97%.2000-2009Liuzhou city road traffic nonfatal injuries seriously for a top men age30～34years old group, the group is1.45times that of women, women over the age of up to65age group, women were2.04times of men, the highest rate in the minor injury from25to29years old for men age group, the group is1.70times that of women, women a maximum of20to24age group, the male is1.13times that of women.④In the years2004～2009, liuzhou road traffic injuries occur motor vehicles for the responsibility of the major car, the proportion is49.47%61.98%, the highest for2004years of11.02times per vehicles, are the same year all other motor vehicle traffic damage occurred1.60times, followed by motorcycle, the proportion is31.07%～46.01%, other than motor vehicle accident rate in recent years has risen.⑤The road traffic injuries in January, the distribution in March, October to December the road injuries occur is higher; on Monday to produce road traffic injuryis the most, on Thursday that at least; A day in the distribution characteristics of road traffic injuries,21:00to24:00damage occur when the accident happened during peak for peak all day, the second peak occurs in19:0020:00points.⑥Ten years road cross-sectional happen once the order to damage, hybrid, difference car type and difference of direction, difference of direction, the difference the car type. The2000～2009average section of road injuries to the highest incidence ordinary sections,2000～2005, the proportion of ordinary sections at about60%, from2006-2009basic maintain at85%or so, Liuzhou city road damage occurred in the higher percentage of bridge road,10years on average about7%.The cement road surface of road traffic injuries average56.5%, the asphalt pavement ten years accounted for34.93%,2006～2009by cement and asphalt pavement damage to drop quickly, sand, dirt road and other pavement type before were in the6%once, since the2006-2009to the rapid growth, accounting for about45%.Ten years traffic control mode, the order to sign and marking, no control, other security facilities, lights and sign and marking, lights, civilian police and lights and pure police command. Almost every year happen in logo marking and no control of the accident to about90%of all accidents.Ten years occurred in dry straight road injuries of about90%of the total, damp, the water and muddy road the incidence rate of around9%, the road the oil, roadblocks and other cases happened accounted for1%.⑦2000～2009liuzhou road traffic injuries occur in rainy days accident for498cases, sunny day for3123cases, cloudy day for393cases, the fog the weather such as wind up for24cases, ten years of all kinds of weather of road traffic accidents points two section, in as a boundary,03years ago under the weather conditions are maintained in for a higher level,03years later began to drop quickly, sunny day in the most significant change, a drop of50%or more.⑧Urban road traffic injuries occur when the accident happened since the space related analysis showed that, the accident point between space clustering, mainly concentrated in areas Donghuan road YuFengOu sections, the total a bridge to fish peak road sections, etc, the road injury ten years project show Donghuan road and Pingshan avenue east mainly southeast side of the accident is higher.[Conclusion]:In recent years, liuzhou road traffic accidents and traffic is slow decline for the injury, traffic accident and traffic the occurrence of injury is obviously time, the crowds, the regional and spatial distribution characteristics; The traffic accident casualties to men and15to44, young Lord. The traffic accident caused mainly by motor vehicle driver, men more than women; Good road condition, the traffic environment easy traffic accidents and traffic injury; Motor vehicle driver driving without a license, traffic signal way for no signal is traffic injuries when the main risk factors. Road traffic injuries in the spatial distribution of the existence of the clustering, traditional epidemiological combining GIS technology, multi-dimensional analysis of road traffic injuries risk factors, the injury that the etiology of the more scientific research. |
