The invention discloses a real-time dynamic variable lane safety control method in an intelligent vehicle-road cooperation environment. The method comprises the following steps that road segment real-time dynamic variable lane safety control is set, which comprises parameters of an opposite conflict region and a control flow; intersection real-time dynamic variable lane safety control is set, an intersection real-time dynamic variable lane comprises a variable guide lane and a reverse variable lane, and lane length, pre-signal parameters and a signal control scheme are set respectively; and the real-time dynamic variable lane safety control method is evaluated according to simulated vehicle trajectory data and a substitute safety evaluation model, and the effect of safety control is judged. Parameters of an opposite conflict area and a control flow in the real-time dynamic variable lane of the road section are set according to drivers, vehicles and traffic flows, the safety control method is evaluated by a substitute safety control evaluation model, the control parameters are continuously optimized, and safe operation of the real-time dynamic variable lane is ensured.
