urban traffic structure in the urban public transport system, rail traffic with a fast, large capacity, low pollution and high efficiency, become an indispensable part of urban traffic structure, is the contradiction between supply and demand of the growing metropolis, cities, effective means to meet the needs of urban traffic. The following table is a rail transport and other modes of urban passenger transport capacity, transportation speed and resource consumption, andso on. Comparison of urban passenger traffic characteristics table 5.1-2 traffic volume (human/h) transport speed (km/people) Road area occupied (M2/people) scope bike 2,000 10-15 3,000 short car 20-50 10-20 wide bus 6,000-9,000 1-2 40-60 0.25-0.5 from the Metro light rail of 10,000-30,000 in long-distance line 3 More than 0,000 40-60 do not occupy an area both in terms of transport over long distances, transport efficiency, or from the level of resource consumption and environmental pollution, rail transport is undoubtedly an effective means to solve the problem of traffic congestion in cities. Especially in urban population strength enormous traffic demand on the route to ease traffic pressure, rail transportation has incomparable advantages. Washington, DC, area of 177km2, and a population of 600,000, is a United States political center. For the Washington Metro system United States second-busiest subway, second only to the New York subway, opened in 1976. Current rail sizesfor 5, station 86, total 171.6km, net annual passenger volume reached223 million people. According to statistics, from 2000 to 2009 vehicle trip down 12.7%, bus travel has increased by 12%. Objectives of the Washington Metro system boils down to the following three points: by driving onto the tracks at the station transfer mode in order toalleviate traffic congestion; For those who will not or cannot drive the person with a better option than conventional public transit; Block highway3、鼠标右键单击我的电脑，选择设备管理，双击通讯端口，选择端口设置，设置每秒位数:19200，流控制:Xon/Foff ，按确定。
