Abstract
In actual traffic safety studies, it is important to consider the differences between a straight and a curved road. We put forward a calculation method of inter-vehicle distance on the curved road in the V2V communication environment. Next, the safety margin (SM) is introduced to characterize the driver’s hazard perception level and the calculation method of the curve SM is proposed. Data under urban curved-roads conditions in Beijing was collected by real vehicle experiments. According to the results of data processing, the variation rule of SM on curved road was discussed. When the vehicle turns at the unsignalized intersection, the change trend of the SM is first decreased and then increased; when the vehicle turns at the signalized intersection, the change trend of the SM value is slowly increased. This study can be applied in curve speed warning systems and adaptive cruise control systems to improve driving safety and comfort.
