In recent years, as the era of electronic payment has brought about the development of intelligent multi-scale forecasting of highway traffic in my country, it has also been developed because of its late start. Expressway intelligence, in simple terms, is the combination of human operation intelligent technology, digital transmission and analysis and professional skills mastery in the process of highway management. This technology can imitate people's thinking and analysis capabilities to ensure that the original plan is normal run. The core point of the goal of realizing highway intelligence is the relationship between the road, the driving vehicle and the owner and the establishment of a relatively stable and efficient transportation route. From the perspective of intelligent areas that have implemented multi-scale prediction of expressway traffic, it is mainly reflected in the form of ETC, multi-scale prediction of networked traffic, that is, according to the province or larger area, a one-time payment method is adopted for all-in-one cards. Form a complete set of intelligent flow multi-scale prediction system system, maximize the consideration of road users and economic development needs, effectively solve the closed flow multi-scale prediction system generated by different attributions or business entities and improve the efficiency of expressway use and service quality , Reduce the corresponding energy consumption and lay a good foundation for the sustainable development of highways in our country.
