Motor vehicles in road transport revolutionized and brought many benefits to human society. Unfortunately, the interests of human casualties have been accrued on the road. Road accidents as a result of a combination of various environmental factors, behavioral and technological occur. Weather conditions in recent years as one of the most important factors affecting road accidents has attracted the attention of many researchers and numerous studies have been conducted in this area.In the present study, the effect of climatic factors on road accidents in the country one of the axes (Axis of Bandar Sirjan) is studied. Therefore, climatic parameters of temperature, ice, snow, rain, cloudiness, precipitation, visibility, horizontal, relative humidity and sunshine hours and accidents as independent variables in the study area were chosen as the dependent variable. After analysis, it was found that the temperature climatic parameters in the study area had the greatest impact on accidents. It was found that the largest number of accidents occurred on weather conditions Sun temperature more than 25 degrees. At the end of the road in terms of accident risk zoning maps in each of the different climatic conditions to the axis of the draw.Unlike cold and dry in the snow and icy conditions most effective factor in the accident, in the south of the country, especially in the arid and hot climate, temperature element, the main cause of accidents. Accordingly, it is proposed the construction of a road weather station at the center of the above, to observe the minute weather conditions, temperature in hot conditions elsewhere. |
