| Abstract: | This paper carries on a deep discussion about the approach of rural highway network layout. From the characteristics of rural highway network, we can get the optimization tree based on importance degree of crunodes, section and route. Combined with expert system, highway network planning layout can be decided. Optimized based on two quantum index-accessibility and detour coefficient, final highway network planning layout can be gotten. The method is applied to the instance of Xinjiang Yili state rural highway network planning, and good result is gotten. |
