摘　　要：在虚拟交通视景中,为了使交通标志标线能拥有各种属性最优,建立了各种交通设施、交通标志模型,在通过一系列的场景整合后,通过改变标志标线的材质以及贴图属性(RGB染色、反射、高光级别、自发光、凹凸等)渲染出多个场景效果。随机选择若干驾驶人对场景进行纵向及横向比较,确定各渲染场景中的最优材质以及贴图属性,然后根据各属性渲染出最优视景。In the virtual traffic scene, a variety of transportation facilities, traffic sign models were established in order to make the attributes of traffic signs and markings optimal. Through a series of scene integration, several scenes were rendered out by changing the materials and map attributes （ RGB dyeing, reflection, highlights level, spontaneous light, bump, etc. ） of the signs and markings. Several drivers were selected in the random to compare the senses in longitudinal and transverse. The optimal materials and map attributes were determined in various scenes. At last, the optimal scene were rendered out according to these attributes.
