Method for evaluating guide marker spatial arrangement based on view superpose analysis

Abstract

Disclosed is a guidance sign space arrangement evaluation method based on sight overlay analysis, which performs effect analysis on a visual area of human through overlay of dynamic sights of pedestrians in space to quantificationally evaluate the reasonability of the 'space arrangement'of the guidance sign. Firstly, the sight of a pedestrian is abstracted into a sector, the farther the distance, the larger the declination, and the worse the effect of space vision, secondly, a pedestrian flow line is obtained according to spatial prediction or in-situ observation, and a vision sector is formed according to each unit time to perform an overlay analysis of a sector sight of a single flow line, finally the flow rate of the pedestrian flow line is utilized as a weight to compute the vision effect of the multi-flow-line pedestrian visual area via weighting. The method makes up for the shortage that the guidance sign design is lack of evaluation tools, provides a quantitative basis for the 'design evaluation' and the 'post implementation review'of the space arrangement of the guidance sign, and has the advantages of coinciding with the cognitive law of pedestrians and being easy to be realized.

Description

technical field [0001] The invention belongs to the field of optimization design of walking space, and relates to the design evaluation of guide signs, especially the rationality evaluation of space layout of guide signs, so as to optimize the guide system of complex spaces and improve the safety and utilization rate of walking spaces. Background technique [0002] The guide sign design includes three aspects: (1) content and size; (2) space layout; (3) relationship with the surrounding environment. Regarding the spatial layout of the guide signs, the national standard "(GB / T 15566-1995) Principles and Requirements for the Use of Graphic Signs" puts forward relevant principles and requirements: "Signs should be placed where people can see them most", "Should be used as much as possible The observation angle of the sign is close to 90 degrees", "The guide sign should be set at a place that is convenient for people to choose the direction of the target, and it should be arrang...

Problems solved by technology

[0006] The method proposed by Lv Yi divides the passenger’s wayfinding process into several stages, and each stage studies the rationality of the guide sign design. However, the research focuses on the guide sign design elements, and compares the successful cases abroad. for qualitative evaluation

Although the visual visibility index proposed by W.H.K.Lam et al. has realized the quantitative evaluation of the guide sign design, "visual visibility" focuses on whether the sign is visible or not, and lacks the analysis of the visual effect of the sign
