摘要
通过分析驾乘人员在高速行车过程中的视觉行为与心理感知,借助车载数码相机等距自动拍照控制系统对珠三角地区高速公路相对高程较高的高架桥段进行取样试验,根据控制系统自动连续拍摄的大量相片,计算和分析高速行车条件下驾乘人员视觉空间的围合程度及其分配比例,发现其视觉空间环境特征以开敞空间和空旷空间为主.针对上述试验结果,提出了适用于高架桥段空旷空间的景观整备方法,以避免高架桥内驾乘人员出现不良的心理感知.
By analyzing the visual behavior and psychological perception of drivers under high-speed driving conditions,the sampling test of the viaduct section of freeway in the Pearl River Delta was implemented with the help of Car Camera Equidistant Automatic Shutter System.Then,the spatial interface enclosure and its distribution proportion of drivers＇ visual space were calculated and analyzed according to the photos continuously taken by an automatic control system.The results show that the visual-spatial environment of drivers is characterized mostly by open and empty features.Based on the above-mentioned details,some landscape improvement essentials for the empty space of elevated bridges are presented to avoid the adverse psychological perception for people driving on the viaduct.
