This appendix provides additional information on the public's satisfaction with the attributes of major highways. It begins with a recap of the findings on overall satisfaction with major highways for the reader's convenience.

Overall Satisfaction with Attributes of Major Highways

Highway travelers were asked to rate their satisfaction with the major highways they used most often in 1995 and 2000. There was a substantial 15 percentage point increase in satisfaction since 1995. There was also a 6 percentage point increase in dissatisfaction. Compared with attitudes five years ago, fewer travelers have neutral attitudes about the major highways they use.

Travelers gave the major highways that they use most often high marks-much higher in 2000 than in 1995-on the attributes of visual appeal, safety, bridge
conditions, travel amenities, and pavement conditions. However, there has been minimal improvement in the ratings of maintenance response time and a decrease in ratings for traffic flow. In addition, there was a 20 percentage point increase in dissatisfaction with traffic flow from 1995 to 2000.
