The aim of this project is to develop the evaluation methods for the design of overhead structures in urban areas; elevated highways, pedestrian decks at station plaza and so on, aided by the computer graphics simulation.In the first year, software of computer graphics was improved for the simulation of overhead structures, especially, in order to improve efficiency of data entering of three dimensional shapes of structures. By employing this system, two type of analysis are carried out.First, the effects of dimension factors of RC-pier of elevated highways upon their landscape are analyzed. From the viewpoint of sense of pressure and stability, the essential factor of landscape is the area ratio of structure and overhead clearance. The evaluation sense is changeable between 40% and 50% of this index.Second, the effects of change of eye point upon the landscape evaluation of the pedestrian decks at station plaza are analyzed. The image of alternative plans of pedestrian decks are changeable by the movement of eye point. For example, the sense of pressure of structures is decreased in general when the height of decks are increased, but it is not clear on the distance view.In the second year, animation system of computer graphics is developed. The animation and the still presentation methods are compared by evaluation tests of landscape design of pedestrian decks. It is cleared that the animation is appropriate for the evaluation of psychological sense of pressure due to the perception of shapes and volumes of objects, but is has little advantage for evaluation of such as sense of picturesque beauty.

该项目的目的是开发用于设计市区架空结构的评估方法；在计算机图形模拟的帮助下，高速公路上的高速公路，车站广场的行人甲板等。在第一年，计算机图形的软件得到了改进的模拟架空结构，尤其是为了提高结构的三个维度形状的数据效率。通过使用该系统，进行了两种分析。首先，分析了高速公路升高的尺寸因子对其景观的影响。从压力和稳定感的角度来看，景观的基本因素是结构和高架间隙的面积比。评估意义可在此指数的40％至50％之间变化。第二，眼点变化对站点广场行人甲板的景观评估的影响。行人甲板的替代计划的形象可以通过眼点的移动来改变。例如，当甲板的高度增加时，结构压力感通常会降低，但是在距离视图上尚不清楚。第二年，开发了计算机图形的动画系统。通过对行人甲板的景观设计的评估测试比较动画和静止的演示方法。可以清楚地看出，由于对物体的形状和体积的感知，该动画适合评估心理压力感，但是评估诸如风景如画的美感之类的评估几乎没有优势。
