Connected vehicles is one of the effective ways to realize intelligent transportation in the future,through the connected vehicles system driving task is more relaxed and safer,the drivers operation is more accurate and rapid,but the challenge to face is the evaluation of system.Whether or not connected vehicles can enhance the perception and judgment of the driver,change the traditional driving behavior,improve road safety is the key points of this study.This study mainly introduced the technology and applications of connected vehicles,analysis the change of driving behavior and the influence on traffic safety at connected vehicles environment based on the information process theory,results show that the security systems of connected vehicles can improve the stability of driving behavior and traffic flow,enhance road traffic safety.

@@矿体的空间定位一般由走向、倾向、倾角来确定,但对凸镜状、扁豆状及柱状矿体而言,相关的产状要素还包括侧伏角(或倾伏角)。所谓侧伏角,就是矿体最大延伸方向(即矿体轴线)与走向之间的夹角,倾伏角则是矿体最大延伸方向与其水平投影线之间的夹角。在同一个含矿脉带内多个矿体所构成的矿体群即形成矿化富集带,其中矿体中心点连线与脉带总体走向之间的夹角即为脉带内矿化富集带侧伏角。确定矿化富集带(矿体)的侧伏角(向
