China's road construction is still facing many problems. First, safety accidents are still prominent, and blocking events such as regional congestion and bad weather are frequent. Second, some areas have already faced the constraints of land and environmental protection, and the space for new construction is very limited. It is estimated that by 2035 passenger and freight transport demand will still maintain an annual growth rate of 2%-3%, and the growth rate of eastern regions will be higher, but the rapid development of passenger cars may exceed this growth rate. Limited by rigid constraints such as land supply and environmental protection requirements, it is impossible to continue to adopt the development mode of large-scale highway construction in eastern China. Third, to a certain extent, it cannot fully adapt to the development trend of digitization and informatization, for example, the emergency information acquisition is not timely, the rescue support ability is prominent, the operation state perception means are single, the dependence on roadside facilities is strong, the interaction means between managers and travellers is insufficient, the experience of collaborative service between vehicles and roads is insufficient, and it cannot fully meet the requirements of automatic driving and fleet driving. The new business form, new mode, toll collection, communication, and monitoring system developed in the 1990s are not suitable for modern service and demand.
