The invention relates to the technical field of road traffic safety, in particular to an expressway exit ramp multi-stage sight induction system. The system involves a plurality of low-frequency single-layer linear induction marks arranged behind a left side guardrail of an exit ramp, a multi-frequency multi-layer linear induction mark arranged behind the left guardrail of the exit ramp, continuous high-frequency protruding road signs arranged on the edge line of an exit ramp deceleration lane starting lane, a plurality of anti-collision buckets arranged at the positions, close to the inner side of the guardrail, of the nose end of the exit ramp, a safety island protection facility arranged at the position, close to the inner side of the guardrail, of the nose end of the exit ramp, and aninformation induction device. According to the system, the above structure is adopted, the single-layer linear induction marks, the multi-layer linear induction mark, protruding road signs, the anti-collision buckets, the safety island protection facility and the information induction device are combined, the visual illusion of a driver is relieved through multi-frequency visual information stimulation, the visual requirement of the driver is met, the speed sense and the direction sense of the driver are improved, and the safety of expressway exit ramp traffic is guaranteed.
