Though the study on the tendency of expressway expansion at home and abroad, the paper analyses expressway reconstruction Project from macro levels of highway net optimization and micro levels of comparing with construction and expansion. And it finally raises some suggestions about optimizing reconstruction projects of expressway by making conclusion of current cases of existing expressway. © (2013) Trans Tech Publications, Switzerland.

Though the study on the tendency of freeway expansion, the paper progressive analyses freeway reconstruction programme from macro levels of highway net optimization and micro levels of comparing with construction and expansion, and provides the frame for determining Freeway Expansion plan, by using AHP-fuzzy method to provide quantized objective basis for subjective decision of freeway expansion.

In order to understand the construction and operation of rural highway in Chinese countryside, this paper analyzed the principle of DEA method and the characteristics of rural highway, and selected no pavement rate, road network density, town access rate, rural highway PCI(pavement condition index) as the evaluation indexes of rural highway. A comprehensive post-evaluation model of the road network was established by using DEA and applied to the construction and operation evaluation on the rural highway of 31 provinces. The results show that the classification of comprehensive effective indexes of rural highway construction in different provinces indicates that the comprehensive indexes of Shanghai, Shandong, Zhejiang, Sichuan, Xinjiang, Liaoning, Gansu, and Beijing are excellent or good and rural highway construction is achieved; other provinces should improve their deficiencies according to their own characteristics; the evaluation process indicates that the range of mileage cannot fully display the rural highway construction is good or bad, and thus the pavement rate and access degree of rural highway should be improved; the DEA method can not only display the evaluated unit level, but also reflect the reasons and the gap of the backward unit in the form of numerical values. This model can effectively guide the construction and management of rural highway. ©, 2015, Editorial Department of Journal of Chang'an University (Natural Science Edition). All right reserved.
