Abstract:

We select 12 objective indexes to construct an index system of evaluation and analysis of highway traffic development. We initially employ the attribute reduction theory of a rough set to reduce the index system, removing its redundancy index. Models C2R and BC2 of data envelopment analysis (DEA) are then applied to the evaluation for 31 provincial and municipal highway development. We analyze their highway traffic development from scale and technology. Results show that only 11 provinces and cities are effective in scale and technology. Most of them are in progressive decrease of scale and technology.This shows that national sustainable development efficiency of highway traffic is not high, especially for scale efficiency. We not only improve utilization efficiency of domestic highway network, but also highlight the introduction and application of technology in future highway traffic development.
