A review of studying the relationship of rural road accidents with geometric design

On our roads, tens of thousands of people are killed or injured every day. Those who walk, bike, or ride in cars to school or to work, play in or near the streets, or go on long trips. A lot of people will spend a long period in hospitals each year as a result of serious crashes, many will never again be able to live and work or play in the same way they did before. Road traffic accidents (RTAs) are becoming a significant global public health and development issue with significant economic and social consequences. Public health and road safety are strongly linked by several contributions and factors (people, vehicle, environment, and roadway). Higher-quality Road design and improvement can greatly contribute to safer roadways and save lives. The primary goal of this paper is to provide a review of some previous research to determine the influence of geometric design elements on traffic accident rates. Increased lane width, heavy traffic, exceeding the speed limit, decreased lane width, and limited shoulder width all increase the risk of an accident. Roads were safer when they have broad shoulders and sidewalks. A narrower median width increases the likelihood of a collision. Curves with a radius of than 200 meters, either single or multiple, were the most dangerous. The addition of superelevation increased the stability and comfort of the trip Improving Road geometric design is one technique to improve traffic safety by reducing the number and severity of crashes on highways.
