its unique Metrobus system. 2. Formation and characteristics of the Metrobus system In general, Metrobus system consists of seven core components, that is, special road rights, modem public bus, horizontal boarding, ticketing outside the bus, passing priority at crossroads, passenger information and bus fleet management systems. The Metrobus system, through the effective combination of special transport facilities and modem vehicles, has such characteristics as large capacity, low investment, flexibility, passenger friendly, high speed, safety, low pollution and low energy consumption. Compared with subway and light-track system, the construction cost of Metrobus system is much lower, but it is similar with the light-track system in terms of passenger carrying capacity and average speed. Furthermore, its construction cycle is short and it is flexible. It could be used as an alternative to the light-track train system, serve as a supplementary solution to the track transport and conventional transport, and greatly reduce the barrier for constructing high-capacity and fast transport system. It has great practical significance in transforming the transport structure in Chinese cities and realizing the public transport priority strategy. Table 1. A comparison of Metrobus system with subway and light-track train systems Means of transport Subway Light-track train Metrobus system Investment/km 600-800 million yuan 200-300 million yuan 20-100 million yuan Passenger carrying capacity 30,000-40,000 people/hour 10,000-20,000 people/hour 10,000-20,000 people/hour Average speed 30-40 km/h 10-20 km/h 10-20 km/h Time from project approval to operation 3-5 years 2-3 years 1 year Time from project approval to completion 8-10 years 4-6 years 1-2 years System flexibility Low Low High Ability to absorb new technologies Low Medium High IV. Feasibility Analysis for the Application of Metrobus System in Some Chinese Cities According to the progress of China''s urbanization and trend analysis, China''s urbanization is likely to develop two modes, that is, the multi-center mode of large cities and super large cities, and the combined cluster mode of medium-sized cities. Under the two modes, neither will witness the extension of large city districts, instead, they will develop into cities or center of city clusters with high-density development. In order to increase the attraction of city centers to residents, to form an organic entirety of different city centers and to promote the formation of the urban development mode of multi city centers, the introduction of high capacity public transport system is inevitable. The demand for speed and high capacity is consistent with the service offered by the Metrobus system. For the four large cities of Dalian, Shenzhen, Suzhou and Xiamen, they have developed the structural mode of city clusters in terms of their status quo and the planned development course. This paper makes a horizontal comparison of the four cities with Curitiba in terms of social and econo本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
