一、市郊铁路是解决大城市市郊客运的重要方式 国外许多特大城市在城市发展中,一方面扩大城市圈,另一方面建立大城市的卫星城,城市圈和卫星城功能关系主要反映在交通水平上。由于现代交通速度提高,使得城市与城市间、城市与卫星城间的距离缩短了。市郊铁路以其综合运达速度快、运送能力大、资源消耗少、污染小等诸多优势,成为较受欢迎的城市交通方式之一,逐渐在城市交通体系中占有更重要的地位。在国外一些大城市交通体系中,更显示出其优势和重要性,例如伦敦市郊铁路客运承担着早高峰期间到达市中心的35％以上的通勤人员;巴黎工作日的高峰期间市郊铁路运量占到40％;纽约市郊铁路承担着全部上下班乘客运输任务的10％,其中的75％持有
First, the suburban railway is an important way to solve the suburban passenger transport metropolis Many foreign mega-cities in urban development, on the one hand to expand the metropolitan area, on the other hand the establishment of large cities satellite city, city circle and satellite city function mainly reflected in the traffic level. Due to the increase of modern traffic speed, the distance between city and city, city and satellite city is shortened. Suburban railways have become one of the more popular modes of urban transport because of their advantages of fast delivery, large transportation capacity, less resource consumption and less pollution, and they gradually occupy a more important position in the urban transportation system. In some major metropolitan transport systems abroad, their strengths and their importance are further shown. For example, passenger transport by suburban London takes up more than 35% of commuters arriving in the city center during the early rush hour. Suburban rail traffic during the peak of the Paris Working Day To 40%; the New York Suburban Railway is responsible for 10% of all commuter passenger transport tasks, of which 75% hold
