Evaluation of Land Saving Effect for Highway Construction based on Composite Index Model

In order to realize a comprehensive effect assessment of highway construction of different levels, the thesis builds up a system of evaluating indicators in a meso-level, which consists of three criteria land saving amount, function and service level and comprehensive return of land usage. Moreover, it nails down the standard value of the land saving index, and determines practical value of each index by taking the actual situation of HengShui-DaMing section in DaQing-GuangZhou expressway into consideration, then carries out non-dimensional treatment to the index and builds a comprehensive index model by employing the multi-factor evaluation method based on entropy method empowerment. Multi-factor composite index model is a feasible approach to assess the land saving effect of a certain highway construction project, thus realizing the definition and comparative evaluation of land saving level.
