On highways and highways, highways often have traffic jams. At that time, many car owners who were stuck on the road discovered that the ETC (E-stop Electronic Toll Collection System) rapid channel was in stark contrast to the manual payment channel: One side was unobstructed while the other was full of traffic. An analysis report by Chengdu Research Institute of Environmental Protection shows that promoting ETC not only saves time for owners, but also helps to reduce air pollutant emissions such as PM2.5.
Deng Ye, a researcher at the Institute of Atmospheric Environment of the Chengdu Institute of Environmental Protection Science and Technology who participated in the study, told the Life Times that carbon monoxide, PM2.5, and PM10 emitted by the vehicle while passing through the ETC lane were within 200 meters of both sides of the toll station. Compared with the manual payment channel, it is reduced by more than 70%. The study shows that the ETC single-lane capacity is 1,000 vehicles/hour, which is five times faster than the manual toll rate and can effectively relieve road congestion.
Usually, a small car idles for 5 minutes at idle, consumes approximately 70 milliliters of gasoline, and is available for driving for one kilometer. Gasoline exhausts more air pollutants due to incomplete combustion at idle idle. Deng also said that during the peak hours, labor is artificial. The passage will cause a large number of vehicles to queue up for payment, and a large amount of vehicle exhaust will be generated within the region, which will affect the air quality and the owner's health in a local area. The ETC fast track can reduce this impact.
Tian Qiao, owner of Chengdu, said that since the installation of the ETC vehicle-mounted device, it will save time and money. At present, the Chengdu Municipal Government is fully promoting ETC, and will add more than 150 dedicated ETC lanes before July 1, 2017, and strive to reach the end of 2017. Achieved more than 80% of the users of Chengdu ETC. This reporter learned that as of September 2016, 29 provinces have achieved highway ETC networking, and the online journey has exceeded 100,000 kilometers. All provinces across the country can reduce atmospheric pollution by promoting ETC.
