“行”是否便捷,通畅已经成为现代都市人生活的重要需求,也成为了衡量大城市竞争力水平的一项重要指标,而一个城市的公共交通系统又是其中的关键。世界各国都公认公共交通系统是解决大、中城市交通问题的最佳策略而且也是城市赖以生存和发展的重要支柱之一。因为公共交通系统具有许多其他交通方式所不具备的优势,例如:运载量大,运送效率高,占用道路少,能源消耗低,相对污染小,运输成本低等。它已经成为大多数居民出行的主要方式,但是由于近年来经济的发展,城市人口,车辆的保有量迅速增长,造成道路拥堵,令公交车辆运营速度迅速下降,由原来的15～20km/h下降至现在的10～15km/h左右,新增的运力被运输效率的下降所抵消,同时由于公交的舒适性较差,等候及抵达目的地耗时较长等因素,造成居民的出行方式向个体交通方式转移,令私有车数量快速增长,导致道路更为拥挤,交通更为不畅的恶性循环。这无疑加剧了居民不断增长的交 Convenient and smooth “line” has become an important demand of modern city people’s life, but also has become an important indicator of the competitiveness of large cities, and a city’s public transport system is one of the key. All countries in the world recognize the public transport system as the best strategy for solving the traffic problems in large and medium-sized cities and are also one of the important pillars on which the city depends for its existence and development. For example, the public transport system has many advantages that other modes of transportation do not have. For example, it has large carrying capacity, high transport efficiency, less occupied road, low energy consumption, less relative pollution and low transportation cost. It has become the main mode of travel for most residents. However, due to the economic development in recent years, the urban population and the number of vehicles have rapidly increased, causing road congestion. As a result, the operation speed of public transport vehicles has rapidly dropped from 15 to 20km / h To the present 10 ~ 15km / h or so, the new capacity is offset by the decline in transport efficiency, at the same time due to poor bus comfort, waiting and arrival of the destination takes a long time and other factors, resulting in residents traveling to individuals The shift in modes of transport has led to a rapid increase in the number of private vehicles, resulting in a more vicious circle of more congested roads and less traffic. This undoubtedly exacerbated the residents’ growing contacts
