| 摘要： | A transferable methodology has been developed for public sector investment that facilitated quantitative evaluations of projected ITS costs and benefits in concert with various conventional improvements. The methodology is called the Process for Regional Understanding and Evaluation of Integrated ITS Networks (PRUEVIIN), pronounced "proven". PRUEVIIN is not a model itself or a software product, it is a technique featuring the combined application of both regional travel demand models and commercially available traffic simulation software in an innovative scenario-based framework. The feasibility and capabilities of an analysis based on the PRUEVIIN methodology were demonstrated with a case study analysis of a broad freeway corridor within the Seattle, Washington metropolitan region. A variety of realistic alternative solutions for the target year 2020 were analyzed, each representing different combinations of conventional and ITS components. This report summarizes the key findings from the Seattle case study and the development of the PRUEVIIN methodology. The Seattle case study demonstrates that current analytical tools and data can be utilized to address key limitations of the current transportation planning process. Although requiring additional effort beyond current practice, analyses based on PRUEVIIN can reveal important positive and negative characteristics of proposed alternatives that contain a range of ITS technologies. |
