The invention discloses a traffic guidance device for a sidewalk in a crossroad. The device includes a support, the bottom of the support is connected with a base plate, the lower end of the base plate is connected with universal wheels, the base plate is provided with a storage battery, the side edge of the storage battery is fixedly connected to the support, and one side of the support is connected with a winding mechanism; a handrail is hinged to the support, the winding mechanism is wound with a rope, one end of the rope is fixedly connected to the handrail, the middle of the handrail is connected to the support through a spring, the upper end of the support is connected with a protective shield, and a solar panel is installed on the protective shield. The traffic guidance device is simple in structure, and through arrangement of a time relay for cooperating with the switching time of a traffic light, the handrail is controlled to ascend and descend conveniently, and therefore thecrossroad can be blocked when a red light is turned on to prevent pedestrians and non-automatic vehicles from running the red light; the traffic guidance device can be widely popularized for use.
