In 2019, wireless geomagnetic detection devices were installed at a total of 280 road intersections in Weiyang District, Beilin District, Baqiao District, and Qujiang New District of Xi'an City. These devices, in coordination with traffic signal controllers, have realized regional coordinated control, anti-overflow control, and inductive control. The renovation has achieved remarkable results and won recognition from various parties, laying a solid foundation for the intelligent development of Xi'an's road traffic in terms of traffic data collection.
