Description

Technical Field

[0001] The utility model relates to the technical field of road traffic accessory devices, in particular to a movable intelligent traffic light in an urban area. Background Art

[0002] Intelligent traffic lights are a research hotspot and belong to the intelligent transportation system. The intelligent transportation system aims to build a future integrated transportation system that can ensure safety, improve efficiency, improve the environment, and save energy based on the multi-connectivity of pedestrians, vehicles, roads, and signal systems through the new generation of information technology, and promote industrial changes in related upstream and downstream industries such as traditional transportation, service control, and vehicle manufacturing. Intelligent traffic lights use artificial intelligence methods to process road and vehicle data collected using various communication and information collection technologies, and output reasonable signal light control strategies to control road traffic lights in order to optimize various traffic performance indicators.

[0003] For example, a Chinese patent (CN219936536U) discloses a movable urban intelligent traffic light, which can be very convenient to move and fix the intelligent traffic light, thereby improving the convenience of using the intelligent traffic light. The light group includes a lamp group, a column and a base.

A threaded hole is provided in the middle of the top end of the lifting plate, the threaded rod is threadedly connected to the threaded hole, and a thread is provided on the outer side of the bottom of the column.

[0004] The above scheme also has the following technical deficiencies: the above scheme is not convenient for adjusting the height of the light group.
