Title:

Statistical Analysis of Weather Related Road Accidents in Iran

Abstract:

Iran has a specific kind of climate due to its geographical location and some effective factors like topography and distance from water bodies. Most of the country is covered by mountain ranges of Alborz and Zagros and some sparce mountains in the interior parts. Most roads pass through these mountainous areas. There are 237 dangerous and snow prone passes. Many of these passes are blocked during cold months by heavy snowfalls, avalanches, blizzards, black ice, dense fogs. Which causes considerable damage to the economy of the country. Inclement weather creates a chronic hazard on Mountainous roads in Iran. Past studies indicate that road collisions rate increase during precipitation and road frosts. The goal of the current study is assessment of relationship between road accidents and weather condition with statistical methods.
