Yizhuang has become an "oasis" without traffic jams, which comes from Baidu's newly released "Global Signal Control and Congestion Mitigation Solution Based on Traffic Large Model". At present, more than 300 intersections in Yizhuang are equipped with intelligent transportation. After the transformation of intelligent intersections, it is equivalent to installing "eyes" and "brains". Many road sections can effectively relieve congestion under heavy traffic pressure, providing a "smooth all the way" travel experience for many regions across the country, including Yizhuang.
