“要提高公共交通行业的运营效率,关键因素不是运营商的所有权问题,而是能否营造出良性的竞争环境,竞争压力才能促使公共交通运营更为高效。”很多年前,美国疾病预防控制中心(CDC)就推荐成年人每天至少要适度地进行22分钟的身体活动(例如快步行走)来保持健康。实际上,只有不到一半的美国成年人达到这个目标,因此,公共交通乘客在步行到公共交通车站和目的地的途中,应当做一些锻炼运动。公共交通乘客每天步行的身体活动时间(约20分钟)要比其他人多三倍,接近美国疾病控制中心的推荐 “To improve the operational efficiency of the public transport industry, the key factor is not the ownership of operators, but whether a healthy competitive environment can be created and competitive pressures can make public transport more efficient.” Many years ago, the United States The Centers for Disease Control and Prevention (CDC) stays healthy by recommending that adults take at least a modest 22-minute physical activity per day (such as walking). In fact, fewer than half of American adults do so, and public transport passengers should do some exercise on their way to public transport stops and destinations. Public transport passengers walk about three times more physically (about 20 minutes) per day than others and are close to what the Centers for Disease Control recommends
