Study On The Effect Of Horizontal Curve To Driving Track On Two-Lane Highways

In this paper, two-lane highway is the object of study and the main content is the study of how the two-lane highway horizontal curve impacts on vehicle trail. We use horizontal radius as primary control variable, use experimental research as the main technical means. We developed appropriate experimental equipment to collecting real vehicle speed and trajectory and then used specialized statistical software to analysis the experimental data scientifically. We obtained the dynamic change rules of the vehicle driving trajectory features in the curve segment of a two-lane road as well as the inherent roles between the traveling speed or trajectory and the curve radius of the vehicle. The research achievement can provide a reference to road line design, road safety design, road facility design and the development of the accident prevention programs. Also it plays an important role in ensuring drivers’ safety and comfortable.
