| Abstract: | A safety distance mathematical model of vehicle longitudinal is estabished based on modeling method of driving characteristic and traditional kinetic analysis of safety distance.Through the real-time detection of driving behavior,the driving characteristics identification model,the driving characteristics,vehicle,road,environment factor and other factors are integrated into the mathematical mode.By calculating and comparing the mathematical model is proven to be higher accuracy and real-time,which has a high application value in vehicle collision avoidance systems research. |
