北京是国内最早提出“公交优先”战略的城市之一。但由于北京是一个1500多万人口的特大城市,截至2006年11月,北京市机动车保有量已达285万辆,而且仍以平均每天1000辆的速度增加,小汽车出行比例持续增长,高峰时段市区主要干道基本处于饱和状态,道路交通拥堵严重。而目前北京的“公交优先”政策实施还不是很到位,北京的公共交通出行只占市民出行总量的25%左右,而世界发达国家一般都在70～80%之间。
Beijing is one of the first cities in China to put forward the “bus priority” strategy. However, as Beijing is a mega-city with a population of over 15 million, as of November 2006, the number of motor vehicles in Beijing has reached 2.85 million and still increases at an average speed of 1,000 a day. The proportion of car trips has continued to grow and peaked The main trunk roads in urban areas are basically in a state of saturation, with serious road traffic congestion. At present, Beijing’s implementation of the “bus priority” policy is not yet in place. Beijing’s public transport only accounts for about 25% of the total travel volume of the public, while the developed countries in the world generally have between 70 and 80% of the total travel volume.
