| Summary | In recent years, numerous constructions and plans for road systems have been implemented to improve the transportation convenience. However, this has resulted in complex guide sign information. Ergonomic engineering is commonly applied in numerous research fields, and visual ergonomics substantially affects transportation safety. Relevant studies have contended that over 90% of information for drivers is obtained visually. Thus, this study adopted visual ergonomics and practical research findings to the designs of diagrammatic guide signs, thereby increasing road users' ability to identify and comprehend guide signs, enabling road facilities to comply with visual ergonomics, and decreasing information confusion and disorientation. Consequently, the benefits of driving are enhanced and energy consumption is mitigated.
This study first analyzes current problems regarding diagrammatic guide signs. To enhance the samples of diagrammatic guide signs on highways, relevant regulations in the United States, the United Kingdom, Germany, Japan, South Korea, and Taiwan are collected, and visual ergonomics, as well as Gestalt psychology, is then applied to the design of diagrammatic guide signs as reference for practical research and experimental designs. The evaluation of the experiment process is divided into two parts as follows: (a) Preliminary analysis, which involves static examinations of guide signs, is conducted to complete information collection and a questionnaire survey for guide sign preferences. (b) Driving simulation, where the previously evaluated guide signs are screened and adjusted to determine differences between the cognition of road users in the driving simulation. Finally, a summarization of the literature review and experiment results was conducted. We anticipate that the findings of this study can serve as a reference for management authorities in developing superior diagrammatic guide sign design. Following are the four primary findings of this study: (a) A comparative analysis between the regulations of diagrammatic guide sign in the United States, the United Kingdom, Germany, Japan, South Korea, and Taiwan (b) Design criteria for enhancing the effectiveness of diagrammatic guide signs on highways (c) Optimal designs for diagrammatic guide signs on highways (d) The process of designing diagrammatic guide signs |
