The Influence Of Planning & Design On The Cost During Mass Transit Operation Stage

For the sake of improving the metropolitan traffic conditions and greeting the World Expo, Shanghai has made great efforts to build the public traffic system boned on mass transit and strive for finishing four hundred kilometers mass transit network before 2010. At that time, the proportion of mass transit's passengers in public traffic system will from fourteen percent to forty percent. Mass transit project may have the better social benefits, but actually it doesn't have an ideal economic performance and still needs the financial from the government. So it is concerned that how to make the project profit by the government, enterprises and investers.To realize the project's gain, there is one way to decrease the operation cost. According to analysis the operation cost of Shanghai Mass Transit Line 1, this thesis finds that in comparison of the operation management factor and social factor, the key to effect operation costs management ability is planning & design. Although the proportion of planning & design cost is very small, it affects the whole life cycle cost strongly. So in fact every operation cost is determined earlier at the planning & design stage.To counter the problems that exist in planning & design, the paper has studied some main questions and made a constructional suggestion in future.
