Development-of Evaluation System of Aesthetics of Landscape with Bridge Using Artificial Neural Networks

本研究以人工神经网路为工具，建立桥梁景观美学评价系统。主要研究结果如下：1.以一座拱桥为例，考虑了43个桥梁景观美学评价项目，确定了影响桥梁景观美学的20个项目。该系统中使用的神经网络成功地训练的基础上进行了问卷调查的结果，使用94个黑白白色照片的拱桥。通过敏感性分析，探讨了这20个项目对拱桥景观美学的影响。2.为了考虑色彩对拱桥景观美学的影响，对25对彩色和黑白白色拱桥照片进行了问卷调查。以某拱桥为例，选取了包括色彩效果在内的53个评价项目，成功地训练了神经网络。对彩色和白色照片进行了敏感性分析。阐明了色彩效果对桥梁景观的美学效果有着重要的影响。

In this research, an evaluation system of aesthetics of landscape with bridge was developed by using artificial neural networks. The main results are as follows :1.For an arch bridge 43 evaluation items of aesthetics of landscape with bridge were considered, and then 20 items which affect aesthetics of landscape with bridge were determined by the use of the developed system. The neural network used in this system was trained successfully based on the results of questionnaires which were performed using 94 black-and-white photographs of arch bridges. Carrying out the sensitivity analysis, the effects of these 20 items on aesthetics of landscape with arch bridge were discussed.2.In order to consider the color effects on aesthetics of landscape with bridges, 25 pairs of color and black-and-white photographs of arch bridges were used for questionnaires. For an arch bridge 53 evaluation items including color effects were selected, and the neural network was trained successfully. The sensitivity analysis was carried our for both color and black-and-white photographs. It was clarified that the color effects strongly affect the aesthetics of landscape with bridge.
