标题：Investigating the effect of geometric parameters influencing safety promotion and accident reduction (Case study: Bojnurd-Golestan National Park road)
摘要：Transport and communication are the major sectors of economy in any country, and this phenomenon is known as one of development indices of countries. Therefore, safety management and road accident reduction are taken into account as key issues. The first step for controlling road accidents is to identify the accident process and factors influencing it. In recent years, considerable researches have been conducted to perceive the relationship among number of accidents, traffic volume, road geometric parameters and environmental factors in the form of accident prediction models. These models are strong tools in analyzing accident and employed for identification and analyses of accident black spots in suburban roads. The use of prediction models obtained from the accurate statistical methods and information of roads and accidents not only are effective in evaluating the managerial and geometric corrections of roads but also make the identification of accident black spots easier and accessible. Present research tried to offer a model for investigating the effect of geometric parameters influencing safety promotion and accident reduction of suburban roads by the use of collected databases. Finally, effective variables have been used for modeling. Then, using statistical data and field work in the studied road, accident analysis models have been performed on them and effective variables have been identified. Also, measures have been conducted for solving problem and safety promotion of roads.
