Respondents at freeway management, arterial management, and transit management agencies were asked to assess the benefits of
specific ITS technologies. In each case, only those agencies actually deploying a technology were asked to provide a ranking,
and the ranking was to be made based on individual operational experience with the technology. Respondents were asked to rate
the technologies on a scale of 1 (No Benefit) to 5 (Significant Benefit). The chart shows the results for freeway management
agencies. The average scores are shown in parentheses and the percentage of responses in each category are shown by different
colors in the bars for each technology.
