ETC brings great convenience to high-speed traffic, which is far more efficient than artificial channels, and is also the trend of the future. However, at present, most high-speed toll stations still rely on artificial channels. In the case of high traffic volume, ETC's efficiency still cannot be fully realized. According to the @Chongqing Morning Post report, news from Chongqing Expressway Group, Chongqing Expressway is accelerating the construction of mixed lanes to further leverage the advantages of ETC, and will add antenna trading functions based on artificial lanes. In the future, when ETC vehicles pass through the artificial lane, they do not need to take a card to swipe the card, and can directly pass through the vehicle and complete the payment. After the completion of the mixed lane, it will make maximum use of lane resources to facilitate the driver's quick passage. At the same time, a few days ago, the second-generation ETC lane technology successfully passed on-site opening test at the Gaotong G65 Banan Mainline toll station and has now been open to the public for trial operation. Technical requirements for the first-generation ETC lanes must be less than 20 km/h. Otherwise, the ETC lane may not be able to successfully read the vehicle information. After adopting the second-generation technology, the ETC lane speed can be increased to 40 km/h. Doubled. Promote popularization quickly.
