The invention discloses an intelligent electronically controlled deceleration strip applied to intelligent urban planning and construction. The intelligent electronically controlled deceleration stripcomprises a base plate, wherein a base groove with an upward opening is formed in the base plate, and a bearing plate is slidably arranged in the base plate in a matched mode; the bearing plate is slidably connected to the wall portion of the base plate, and moves in the vertical direction along the wall portion guiding of the base plate; a jacking spring for jacking the bearing plate is arrangedbetween the base plate and the bearing plate; a plurality of lock latch mechanisms for locking the position of the bearing plate are installed in the base plate, and the lock latch mechanisms are correspondingly installed on two length end sides of the base plate; at least one of the lock latch mechanisms is connected with a buffer induction mechanism, and a inclined plane guide rail for guidingthe buffer induction mechanism is arranged on a lock latch base of the lock latch mechanism connected with the buffer induction mechanism; a plate pressing groove for guiding the buffer induction mechanism to move in the horizontal direction is formed in the bottom of the bearing plate; and the inclined plane guide rail guides the buffer induction mechanism to move in the vertical direction and guides the buffer induction mechanism to slide in the horizontal direction at the same time.
