Research On Construction Schedule For Urban Rail Transit

At present, the construction of the urban rail transit in China is during the peak time. The theory of planning on urban rail transit is at the beginning stage. So there are many problems appearing in construction progress. One of them is unreasonable schedule which has gathered more attention than before. In order to avoid such problems, we should do much research on them before starting constructing. At first, we must make sure whether the opportunity is ripe. Both of premature and late will impact the efficiency of urban rail transit. Then the period of constructing should be decided before calculate the construction scale. The factors deciding the construction scale include urban space development, urban transport development, and urban social environment. According the calculate model we can decide the construction scale. Choose proper line from the line network planning with the classification theory. Based on "Nodules point importance" Theory and "Cost-Benefit" Theory, form the perspective of the importance of the line and the time of cost recovery, arrange the order of the subway lines in recent years. The dissertation just supplies a method to solve problems above.Solve the problem on construction opportunity, put forward the necessity in constructing subway from urban space development, urban transport development, urban social environment which based on the ban. Give the standard of constructing subway from urban space development, urban transport trips, city vehicle fleet, the level of urban economic development. At last, provide an access principle of constructing subway which is a reinforce from ration for the construction opportunity.Put forward a method for deciding the period of constructing subway in recent year which provide a Basis for the construction scale. Calculate the construction scale by traffic demand, investment possibilities, and engineering feasibility. According the weight theory, the artical giving a reasonable construction scale which is in the range of traffic demand and economic strength.Solve the problem on construction order. Choose proper line from the line network planning with the classification theory. Based on "Nodules point importance-Traffic Location" Theory and "Cost-Benefit" Theory, we can arrange the order of the subway lines in recent years. The decision-makers can refer the result to decide which line should be constructed first according the actual situation of the city. Using the theory, make research and analysis on the construction opportunity, construction scale, construction order in Shijiazhuang. At last provide a reasonable construction plan and recommendations.
