北京是中国的首都,也被戏称为“首堵”。车辆多是一个原因,城市规划不合理是另外一个原因。中国很多大城市的交通也或多或少的存在着与北京相似的情况。现就我们的一些观察提供给大家参考。1以大城市为中心的辐射道路网把城市变成了车辆集散中心以北京为例,从北京起始的有京广、京藏、京沈、京昆等十几条高速公路,另外还有一些低等级公路。粗略算算这些道路上的车流量,就可估计出每天有多少外地车辆要经过北京市区。 Beijing is the capital of China and is also nicknamed “the first plug.” One of the reasons vehicles are numerous and urban planning is not reasonable is another reason. Traffic in many big cities in China is more or less similar to that in Beijing. Now some of our observations provide for your reference. 1 Radiation Road Network Centering on Big Cities Turn the City into a Vehicle Distribution Center Taking Beijing as an example, a dozen expressways starting from Beijing, such as Beijing-Guangzhou, Beijing-Tibet, Beijing-Shenyang and Beijing-Kunming, Some low grade roads. A rough calculation of traffic on these roads, we can estimate how many vehicles each day to go through the Beijing urban area.
