| 摘要： | Variable Message Sign (VMS), one of the key Intelligent Transportation System (ITS) components, provides access to realtime traffic information on the road network, which helps choose the best route and mitigate traffic congestion. However, the compliance behavior of the drivers depends on various factors such as size, font, color, light intensity, vertical and horizontal position, the distance of the VMS installation site from the displayed event, message display duration, etc. Given the limited funds and resources available, it's crucial to concentrate the investments on only the most highly effective VMS. Hence, there is a need for a thorough VMS assessment methodology that analyzes installation techniques, applications, and deployment strategies for these signs. This paper provides a comprehensive overview of methodologies used for assessing the effectiveness of VMS and proposes a framework for selecting the assessment methodology suitable for the particular design aspect, intended use, and operational practice. This proposed framework takes into account all three-assessment aspects i.e., design, application, and operation, both qualitative and quantitative VMS effectiveness measures, and the most commonly used assessment methods i.e., survey methods, driving simulation methods, and field study methods. Assessment of the effectiveness of VMSs is expected to improve VMSs' operational practices and allocation of resources by investing in effective VMS practices. |
