2008 during the Olympic Games , to ease traffic congestion, Beijing implemented the odd and even number lines . October 11 that year onwards, started tail number limit line . Ie five working days to be suspended one day for private cars , the vehicle shall every two numbers on the road. 2008 implementation of the tail number limit line on the first day , 800,000 private cars suspended , at present, the amount of 5.3 million cars in Beijing , is expected to have over a hundred thousand cars a day suspended . Last September, the Transportation Committee released September traffic congestion work report mentioned that in 2013 , the city will assess the specific time , specific regions odd and even numbers to implement measures to limit vehicle feasibility .
According Kero  Throttle Body  noted that Beijing will control the vehicle size, and for the first time defined the specific control number . Yesterday, the Beijing Municipal Environmental Protection Bureau issued " Beijing Clean Air Action Plan 2013-2017 focuses task decomposition " program, to the end of 2017 , the city's vehicle fleet controlled at 6,000,000 or less. Total control policy will be completed by the end of October this year . Sources of PM2.5 in Beijing , vehicle emissions account for 22.2% , is the " first big ."
By the end of 2017 , the city's vehicle population will be controlled at 6,000,000 or less. Why is the target set at 6,000,000 ? Authorities to develop this indicator may still take into account the capacity of the road network and other transportation infrastructure progress , " on the one hand to gain time , one must make sure that car was able to open up ."
With tail number limit line , a specific period of time , the original intention of the limit line area , it may be important for the protection of major events or lots of traffic comfortable , but often major events of the time there is uncertainty . For example, she said , if the nest, the Workers' Stadium because of the limit line activities that require the transport sector through the media to inform the public in a timely manner .
Beijing can often blocking points, such as international trade, Zhongguancun , Bird's Nest , the Workers' Stadium and other locations for traffic assessment , in what period of time , which would produce much road traffic, limit line will reduce the number of traffic flow , traffic departments should predict well in advance , this increases the feasibility of implementation .
Limited number of very obvious shortcomings , there is not enough flexibility , such as members of the public during certain time periods or regions do need to drive, hard limit will bring a lot of inconvenience to the public . From abroad , this kind of rigid measures restricting the number of small, they are more used to encourage and guide the way . Such as Singapore 's policy to encourage people to voluntarily restricting the number of government , while giving tax relief incentives.
According to statistics, Beijing heavy pollution days per year over 40 days . Among them, a very heavy pollution days occur once a year or once every two years . Relevant responsible person said , considering the odd and even number rows pollution levels and duration may be.
Deal requirements, where to enter the inner ring road ( excluding ) the vehicle must apply for other cities to Beijing permits, peak hours only allowed to enter within the rings , suburban county towns can not enter. According to the relevant personnel transport sector , due to Changping , Daxing , Tongzhou and other six ring suburban counties in the morning and evening peak hours are often traffic jams , and many vehicles need to go through these areas to Beijing , so restricting non Jing Ji region is also this part of the vehicle included within the scope of the limit line .
According Kero   Throttle Body  learned this year in August , a small passenger car car Yaohao rate has reached one eighty-four that 84 people grab a plate. After two years of accumulation, Yaohao pool number exceeded 155 million, and the number is still growing.
With the continuing decline in the success rate , but also spawned a whole family to learn to drive assault accounted pit Yaohao " sham litigation " transfer license " car brand " and other chaos . There are also some people who believe in the car needed "money indicators" rumors and deceived.
In fact, the introduction of such a measure is not sudden . Two sessions at the beginning of Beijing , the Beijing Municipal People's Congress, vice mayor Chen Gang said that although Beijing has taken a small passenger car Yaohao policy , but every year more than 20 million units of wave number indicator is still large. Beijing will control the growth and use of cars , and in particular the use of existing motor vehicle use under extreme weather to take economic, legal and other measures.
It is worth noting that this year had eight Although Yaohao car , but on the 2013 index of small passenger cars of specific measures and targets regulatory limits were not disclosed .
