Abstract :
Important part of land transport infrastructure and economy of every country and region in which the various geographical and climatic conditions vary. The awareness of these factors can help reduce damage to the safety of transport in the human and financial. Goals that are pursued in this study - 1 described a method for determining the probability of crisis situations and Slippage (NP1-NP9) along the two roads - the safety contour statistical analysis of meteorological weather stations. In this study, safety-oriented suburban transport network Semnan - Surrey were analyzed with a length of 200 km .In the study, Monthly temperature, precipitation and humidity the classification, classification V of each month to determine the climatic conditions of various climatic conditions of the matrix was used. After calculating the probability of each one of atmospheric conditions during the period studied stations the diagrams of the software used to interpret s. Excel extraction. The main achievements of this research are classified in terms of road safety andSlippage freezing cold and warm months of the year and the area is unsafe.
