Abstract:
In order to evaluate the performance of underground road transportation engineering design projects, an evaluation hierarchy of underground road transportation engineering design project was established based on oriented security, technology, economy, efficiency of operation and environment. Data envelopment analysis (DEA) method was introduced to analyze the adaptation of underground road transportation engineering design evaluation. According to homonymous provision of DEA to input and output indexes, number of conflict point, construction costs and traffic delay were chosen as input indexes, and design traffic capacity and illuminance were chosen as output indexes, which took full account of the relevance between indexes and evaluation objects, and easy to be quantified. Finally, by taking the New World Underground Tunnel Project in Xian as an example, the DEA method was verified by the selected indexes, using BCC (propose by Banker, Charnes and Cooper) model, a special DEA method with variable returns to scale, was used to get the overall efficiency of the 10 underground road transportation engineering design projects, and then the technical efficiency and scale efficiency of those 10 design projects were analyzed and the cause of DEA invalid in each project was also revealed, so that the improvement direction and advice of some projects could be pointed out. The results show that compared with CCR (proposed by Charnes, Cooper and Rhodes) model whose returns to scale is constant, BCC model has a stronger adaptation to evaluate underground road transportation engineering design projects, and get the overall efficiency of different underground road transportation engineering design projects. When the overall efficiency of multiple design projects is 1, the method can not only obtain the relative merits of those projects, but also calculate input redundancy rate and output deficiency rate of each DEA invalid project to point out the improvement direction and step size, avoiding deficiency or surplus of input and output factors as well as wasting of resources.
