In real life, no one seems to question the role of traffic lights , in fact it is the most basic traffic control , separation of conflicting traffic , allowing more efficient traffic operations and safety . Rapid growth in motor vehicles today , people have the desire of vehicles has also expanded . Liberalism has always believed in the market "invisible hand " of the force , I believe that through people rational choice and full competition , an optimal welfare state can be achieved naturally . However, the cars produced by the various " externalities" to break this myth : intensified traffic jams , accidents appalling mortality and the high PM2.5, it will make people more alert, to see the other car community a "face" ?

      According Kero  Throttle Valve    understood that the national air pollution control for a guide to action. Over the past year , Guangdong, Beijing and other places has promulgated air pollution prevention plan , the current air pollution control has been a key area of ​​the central and local governments unprecedented attention , " Action Plan " involved in the automotive industry is expected to be a strong policy implementation .

It is commendable that, compared with the previous environmental policy , the policy bias industrial upgrading and energy structure adjustment , no longer blindly emphasized limit total vehicle , but tackling the problem , considering the emissions from new cars in the car and controlled through strengthen urban traffic management and a series of measures to control pollution and congestion problems , will provide an opportunity to upgrade the automotive industry . Such as oil quality improved, yellow car out , low-speed car upgrades, new energy vehicles are the automotive industry to promote transformation and upgrading of the problem has been outstanding .

Yellow cars and other motor vehicles out of the old has been troubled by the problem of big cities . 2012 yellow car ownership of 15 million , accounting for 14% of car ownership , but more than 60% of emissions of nitrogen oxides, is the focus of automobile emissions . If the yellow car out policy can be implemented in the next four years , no doubt, buses and heavy-duty truck industry will benefit from the yellow car out of scrap brought update requirements .

That " research shorten buses, taxis mandatory retirement age ", to improve the quality of public transport use . Bus market is mainly dominated by scrapped update requirements , and if the bus can significantly shorten the mandatory retirement age , will significantly increase the demand for buses .

      According Kero Throttle Valve   learned to effectively solve the fuel quality and supply of urea and other related issues . Improve fuel quality, " in 2017 before the end of the fifth stage of the national supply in line with national standards for motor gasoline and diesel ." Car oil does not match the automotive industry 's ills , such as to solve this problem, upgrade the emission standards for the automotive industry clear obstacles . In addition, the proposed "speed diesel trucks with urea supply system construction ." If the car with urea supply system construction progressing smoothly , it will be China IV standards and lay a good foundation.

Nobody likes "by" taxes and fees . Moreover, steady economic growth in a society growing love for cars , " deprivation " or " down" those car-related personal welfare , without exception, will encounter strong resistance . Therefore, if the government expects the purchase or through the car congestion charging , to change people 's behavior car ownership and car , then some of the necessary communication and critical issue , and should be sufficient attention.
