The subway in Sendai City was just completed in 1987. It was a great chance to conduct an impact study both before and after the introduction of the subway. The purpose of this paper is to analyze the characteristics of the subway. And the specific objectives are as fallows.1. To conduct field surveys of subway impact in different two periodical time. One is before the introduction of the subway and the other is after the introduction of the subway. 2. To Analyze the characteristics of the subway user, especially, to find the transportation mode ever used. 3. To build up a modal choice models in order to determine the role of parameters for both before and after. 4. To find the appropriate policies to stimulate the subway usage in the future.With regard to the subway in Sendai, only a few people changed their choice of mode from car to subway. Most of the passengers of the subway have shifted from the bus users. The results of the model analysis are as follows:1. The most important variable of the modal choice model is the an availability of the parking lots in downtown. 2. The second important variable is an availability of the car as it is. Because private car is the most convenient mode for commuting, if car is available then they try to use it. Results from the models of both before introduction of the subway and after introduction of the subway, it was found that by leveling up of the services, the importance of the service variables such as time saving would increase. In a middle-sized city such as Sendai, time's loss is caused by transfer at the subway stations seems to be significant.

1987年，仙台市的地铁刚刚建成。这是一个很好的机会，可以在地铁引入之前和之后进行影响研究。本文的研究目的是分析地铁的特点。具体目标如下：1.对不同时段的地铁影响进行实地调查。一次是在地铁推出之前，另一次是在地铁推出之后。2.分析地铁用户的特点，特别是曾经使用过的交通方式。3.建立了模式选择模型，以确定参数在前后的作用。4.寻找合适的政策来刺激未来地铁的使用。对于仙台的地铁，只有少数人改变了他们的选择方式，从小汽车到地铁。地铁上的大多数乘客已经从公交车使用者那里转移了。模型分析的结果如下：1.交通方式选择模型中最重要的变量是市中心停车场的可用性。第二个重要的变量是汽车的可获得性。因为私家车是最方便的通勤方式，如果有车，他们就会尝试使用。结果从地铁开通前和开通后的模型中发现，随着服务水平的提高，时间节约等服务变量的重要性会增加。在仙台这样的中等城市，在地铁站换乘造成的时间损失似乎是很大的。
