In recent years, an innovative Intelligent Guidance System for traffic safety under limited visibility conditions appeared and evolved. According to prevailing visibility and traffic conditions, such systems can provide roadway outline reinforcement, vehicle active guidance, rear-end collision warning functions by changing brightness, color, flashing frequency, etc. of the illuminant guidance facilities. Rear-end collision warning function is the marked feature different from traditional guidance facilities. This paper elaborates main principle, system configuration, word mode, control strategy of such system. Especially, emphasis is put on the analysis of key control parameters such as threshold of red lamp duration, quantity of trigged red lamps, which impact practical effects of such system greatly. Regarding the particular rear-end collision warning function, the author use time series chart of trigged red lamps status and list table of key parameters change to induce and optimize key control parameters configuration. The relationship of safe spacing between vehicles, advised speed limit, threshold of red lamp duration and quantity of trigged red lamps is established. And this can be referred to improve the practical effectiveness when such systems are constructed and used.
