- W627266618 abstract "Safety issue on gravel roads is attracting concerns from state and local road agencies, as gravel roads account for a considerable proportion of total road mileage. Similar to paved roads, a number of factors are likely to be important to the occurrence of crashes on gravel roads. However, the manners by which different factors impose their influences on crashes on gravel roads may differ from those of paved roads, as gravel roads have different surface design, roadside development, traffic control devices and maintenance from paved roads. In Kansas, over the past ten years, an average of 50 people died and 165 people got disabled every year as the result of crashes on gravel roads . The annual economic loss due to crashes on gravel roads is more than 200 million dollars each year. Therefore, it is important to study crashes on gravel roads to address safety related issues. This study utilized Kansas Accident Recording System (KARS) database and focused on crashes that occurred on gravel roads in Kansas during the 3-year period from 2003 to 2005. Factors that are likely to be important were selected, and the relationships of each factor with respect to surface type and crash severity were studied by applying Chi-Square test. The statistical results show that nearly all the factors considered were dependent on surface type and crash severity, which means they have very significant impacts on the occurrence of crashes. Gravel roads were found to be more likely to have fatal and injury crashes than paved roads. Many driver related factors were also contributory towards fatal and disabled crashes both on paved and gravel roads. Environment and road related factors had more influences on the occurrence of crashes on gravel roads than they did on paved roads. The findings in this study are helpful in identifying crucial factors which have significant propensity of resulting in either more crashes or higher severities on gravel roads." @default.
