复合型城市街道空间信息化布局规划研究

Study on information layout planning of street space in compound urban

传统城市街道布局规划方法忽略了对三维空间的数字化重建,缺乏空间描述能力,导致规划结果与理想效果相差较大。为此,提出基于数字技术的复合型城市街道空间信息化布局规划方法。三维数字化重建复合型城市街道空间,构建出行效用满意度目标函数,分析机动车、非机动车、行人通行空间需求,确定街道空间出行能力,计算街道通行效率,满足最低空间需求情况下,完成街道合理性规划。实验结果表明:该方法街道规划结果与理想配置方案一致,能够保证交通畅通、行人安全出行。

The traditional urban street layout planning method neglects the digital reconstruction of three-dimensional space and lacks the ability of spatial description,which leads to the great difference between the planning result and the ideal effect.Therefore,this paper puts forward the method of urban street spatial information layout planning based on digital technology.The compound urban street space is reconstructed by three-dimensional digital,the traveling utility satisfaction objective function is constructed,and motor vehicle,non-motor vehicle,and pedestrian traffic space demand is analyzed.Then,the street space travel capacity is determined,the street traffic efficiency is calculated to meet the minimum space demand,which completes the rational planning of the street.The experiment results show that the street planning results of this method are consistent with the ideal configuration scheme,and can ensure smooth traffic and safe pedestrian travel.
