A one-way travel restriction device is proposed. This device can be used on the road to limit the one-way traffic of vehicles, avoid retrograde, private car parking space will be occupied sometimes, and the unsafe factors such as occupying the road at the construction site or road in dangerous state. At present, the one-way traffic restriction on the road mainly depends on the use of traffic police, which is not only inefficient, but also wastes a lot of human resources. One way travel restriction device can solve the above problems. The one-way travel restriction device has complete functions and works efficiently, quickly and conveniently, which conforms to the requirements of the times. So how to meet the needs of modern people in the development of intelligence, mechanical and electronic information integration of the control operation structure provides the possibility of practicality, has a very large development value and broad market prospects.
