Potential Payoffs From Ivhs: A Framework For Analysis

The purpose of this study is to provide a logical framework for the identification and evaluation of alternative Intelligent Vehicle Highway Systems (IVHS) functions, to sort by importance, and to specifically relate the various IVHS functions with the public sector goals they might serve. Toward this goal, an analytical sensitivity study was performed to estimate the benefits of those functions associated with modifying the speed-density-flow curves through the application of vehicle automation. Some analysis was also carried out to assess intersection throughput when signalization is coordinated with automated vehicles. A new computer tool called DEMOS was used in these analyses. Second, an extensive literature search was carrried out to gather the results of studies of benefits performed.
