In order to ensure traffic safety operation under limited visibility conditions, this paper provide an innovative solution - Intelligent Guidance System for Foggy Area Traffic Safety Operation. This Intelligent guidance system mainly consists of visibility tester, illuminant guidance facilities, traffic flow detectors, variable message signs, local and superior controller. According to different visibilities and flow conditions, system controller can adjust brightness, color, flashing frequency, etc. of the illuminant guidance facilities to implement guidance strategy. The system can provide roadway outline reinforcement, vehicle active guidance, rear-end collision warning and safety information advice functions. The biggest advantage of the system is the rear-end collision warning function, which dynamically generate red warning belt to indicate the following space, thus, to ensure vehicles to pass foggy road section safely to great extent. Constitution of system, principle of operation, and control strategy of system are elaborated in this paper.
