The invention discloses an intelligent lifting type forced road speed bump. The forced road speed bump comprises an intelligent vehicle speed detecting and judging system, a power supply module, a lifting drive device, a step-shaped iron lifting platform, two sliding blocks, two springs and two protective cylinder sleeves, wherein the lifting drive device is connected with the step-shaped iron lifting table and controls lifting of the step-shaped iron lifting platform; the two sliding blocks are mounted on two sides of the upper part of the step-shaped iron lifting platform respectively, energized spiral armatures are arranged in the sliding blocks, and the two sliding blocks are connected with the two protective cylinder sleeves through the springs respectively; the energized spiral armatures and the lifting drive device are connected with the intelligent vehicle speed detecting and judging system respectively; the intelligent vehicle speed detecting and judging system is connected with the power supply module. The vertical barrier height of the speed bump is controlled through two times of intelligent detection and judgment of vehicle speed, forced speed reduction and warning are performed on overspeed vehicles, the safety and the taking comfort of running vehicles based on speed limit regulations are guaranteed, and potential safety hazards caused by traffic disturbance in person and vehicle mixed road sections and particularly vehicles' violation of speed-limit standards are prevented.
