长期以来,我国城市道路系统功能不分明,交通性和生活性道路功能合一,不同动力性能的车辆混行成为我国城市交通的普遍问题。当前,自行车对城市交通干扰最重要的表现形式也莫过于机非混行。所以,谈及自行车,很多人认为它是公交的敌人,是造成交通堵塞甚至是交通事故的元凶。 For a long time, the functions of urban road system in our country are not clear, the functions of traffic and life are combined, and the hybrid vehicles with different power performance become the common problems of urban traffic in our country. At present, the most important manifestation of bicycle traffic jam to urban traffic is none other than non-commingled. Therefore, speaking of bicycles, many people think that it is the enemy of public transport and the culprit in causing traffic congestion and even traffic accidents.
