With a relatively high proportion in disabled people, the visually impaired population faces the double demands of general travel and necessary work. At present, there are many problems in the construction of guide space in China, such as nonstandard and non-complete, resulting in the travel inconvenience for the visually disabled people. In order to meet the travel demands of the visually impaired population, the public spaces around the blind massage parlors within the Fourth Ring Road of Beijing are selected as the research samples. In view of three spatial dimensions, i.e. geographical point (crossing space), line (blind sidewalk space) and surface (entrance square space), the visually impaired population safe travel evaluation system is established through the Fuzzy Analytical Hierarchy Process and the Multi-factors Fuzzy Evaluation Method. The results reveal the existing problems:in point space, low degree identification of the blind people; in linear space, serious encroachment of the blind sidewalk core space, in surface space, poor guidance to the entrance of the blind facilities. The overall evaluation of the guide environment tends to be at an "General" level, in which the evaluation scores of safety, standardization and continuity are relatively low, the comfort and identification scores are medium, and the accessibility scores are high. Based on the evaluation results, three suggestions were proposed for the block guide environment optimization to improve the guide space friendliness for the visually impaired population in Beijing, and to provide references for the improvement of the urban guide space in the future.
