Abstract

The aim of this study is to develop usability evaluation indicators to analyze factors that affect user convenience, such as easily recognizing intelligent vehicle speed warning systems for drivers and pedestrians passing through the pedestrian safety zones, understanding expressed information, and actively reducing speed. For empirical and scientific usability evaluation from a user's point of view, this research defines evaluation items and establishs 13 evaluation indicators and a survey questionnaire was designed for user survey evaluation through the expert Delphi analysis and detailed indicator evaluation. The usability evaluation indicator was categorized into Usefulness and Satisfaction, each derived into four evaluation areas, and the detailed evaluation items were derived into 3 Perceptibility, 5 Functionality, 2 Sensibility, and 3 Trust. The outcomes of this indicator analysis and development are anticipated to be useful as a universal evaluation criterion for the usability evaluation of smart traffic safety signs, and by improving the system interface based on this, it is expected to contribute to supporting citizens' pleasant walking environment and spreading awareness of safe driving in the future.

数字交通安全标志可用性评价指标开发研究——以智能车速预警系统为例

本研究的目的是制定可用性评价指标，分析影响用户便利性的因素，如易于识别驾驶员和行人通过行人安全区域的智能车速预警系统，理解表达的信息，主动减速等。为了从用户的角度进行实证科学的可用性评价，本研究定义了评价项目，建立了13个评价指标，并通过专家德尔菲分析和详细指标评价设计了调查问卷进行用户调查评价。可用性评价指标分为有用性(Usefulness)和满意度(Satisfaction)，每一个都衍生出四个评价领域，详细的评价项目衍生出3个感知性(perceptability)、5个功能性(Functionality)、2个敏感性(Sensibility)和3个信任(Trust)。该指标的分析和开发结果有望成为智能交通安全标志可用性评价的通用评价标准，并在此基础上改进系统界面，为未来支持市民舒适的步行环境和传播安全驾驶意识做出贡献。
