On October 26, 2020, Sanya Public Resources Trading Center released the winning bid announcement of the "Sanya YashaHui Competition Area and Yasha Village Intelligent Traffic Sign Construction Project and Traffic Intersection Signal Upgrading Project", and the project bidding unit is Sanya Traffic Construction Management Co., Ltd., and Guangdong Nuosha Construction Group Co., Ltd. won the bid with 46277087.55 yuan.
According to Liu Gan, president of Jiangsu Kechuang Vehicle Networking Industry Research Institute, the project is by far the largest city-level project application of the digital networked traffic guidance system based on the upgrading and transformation of panel display active luminous traffic signs, involving hundreds of sets of intelligent dynamic signs, variable lane signs and intelligent signal lights.

Liu Gan, president of the Jiangsu Kechuang Vehicle Networking Industry Research Institute, said that the goal of vehicle and road coordination should be less traffic accidents and higher traffic efficiency. In order to achieve this goal in the artificial driving stage, the technical path should allow the driver of the vehicle to establish an information interaction with the road, such as traffic regulations on the road, environmental conditions, road conditions, traffic capacity and other information. For a long time, static traffic signs have long solidified limited road space resources and cannot adapt to the needs of diversified travel changes. Digital networking technology is widely used in road nodes and roadsides, which can allow travelers to predict the road conditions in front (downstream) that are about to arrive but are invisible in parallel time and space, so as to actively make predictive decisions and interactive choices. Although Internet navigation technology provides more travelers with functions such as destination positioning, path selection, scene prediction, etc., because it is based on the existing or unreasonable and unscientific road traffic environment and facilities, it cannot significantly improve the bad habits of driving tasks and the road driving environment. The still high incidence of sudden driving incidents and traffic accidents is one of the important causes of road traffic congestion; The failure of more drivers to interact with traffic rules and predict the road ahead is another important cause of traffic accidents and increased congestion.
The technology, also known as the "intelligent network three-level traffic signal guidance system", has been successfully piloted in a small area such as Boao in Hainan Province, the national (Wuxi) Vehicle Networking Pilot Zone, and the Xiamen Chenggong Avenue. After the completion of the high-standard and high-quality implementation of the Sanya Digital Networked Traffic Guidance System Project, the signal lights, variable lanes, and dynamic direction signs are expected to be "data opened" for the first time, and the urban road traffic organization realizes the synchronous multi-source big data application of time and space, and the intelligent networked digital traffic signs that are clearly recognized around the distance can significantly reduce traffic accidents, improve the efficiency of road network traffic, and give Sanya citizens the most direct intelligent traffic experience.
