In the expressway reconstruction and expansion engineering, the form of rightward zone is increasingly adopted, and its\ncomplicated traffic conditions can easily cause traffic accidents. In order to quickly and effectively grasp the traffic risk of the right\ndiversion section, this study employs average speed, the coefficient of variation, the equivalent minimum safety distance, and the\ndeceleration as evaluation indexes of driving risk, and then analyses the influence rules of traffic volume, the proportion of large\nvehicles, and the length of the transition section on each evaluation index by using Vissim simulation software. On the basis of\nthis, we determine the weight of each evaluation index by the entropy method and establish the driving risk index evaluation\nmodel of the work zone with multiple linear regression.
