Abstract

Guide signs are important traffic management measures to ensure fast and safe passage on highways. With the gradual construction of China's highway network, the transportation mode has shifted from the early single line travel to network travel with the interchange between multiple highways. However, the content form and combination layout of traditional guide signs are difficult to match the real environment, which is not beneficial for drivers to recognize information quickly and safely. This paper systematically summarized the current status, research hotspots, existing problems, optimization measures, utility evaluation methods, and future development trends of standard specifications for highway guide sign systems at home and abroad from the four aspects, including the layout design, information content, position setting, and utility evaluation of guide signs. The review shows that from the perspectives such as ergonomics, psychology, physiology, and cognitive science, it is possible to analyze the influence of the selection and arrangement of information elements in guide sign layouts on the legibility of drivers. The research on the information content threshold of guide signs and information release process of guide systems should comply with the information processing characteristics of drivers. Meanwhile, the technologies including the adoption of diversified data collection and aggregation, driving simulation and human factor testing, multi-dimensional data mining modeling, and immersive mechanism analysis were employed to study different scenarios for guide sign setting, thus providing theoretical support for scientific and reasonable guide sign setting. By adopting the methods such as descriptive statistical analysis, multi-objective weighting, and comprehensive quantitative evaluation, a comprehensive evaluation of the setting effect of the guide sign systems can be achieved.
