On the 24th, Qianfang Technology and Hongquan IoT signed a strategic cooperation agreement. According to the agreement, both parties will jointly develop the domestic car-road cloud integration market to assist in accelerating the integration of car-road cloud. In the future, Qianfang Technology will introduce a full-stack technology including C-V2X protocol stack, car-road coordination technology, edge perception algorithm, and cloud-edge management technology, committed to the construction of roadside clouds, edge, end devices and cloud control platforms. Qianfang Technology's car-road coordination products and solutions have been innovatively applied in traffic scenarios such as highways and urban intersections. For example, more than 100 intelligent intersections deployed in Beijing CBD, Wangjing and other places have improved traffic efficiency through refined traffic management, signal optimization and car-road coordination services. On the Beijing-Taiwan Expressway, Yan-Chong Expressway (Hebei section) and other places, C-V2X/5G car-road coordination technology is used to achieve functions such as vehicle-road information interaction, risk monitoring and early warning, traffic flow monitoring and analysis, and have typical car-road coordination application scenario customization development capabilities.（By Hu Haoqiong, Caixin Journalist）
