Appendix: User Satisfaction Survey and Results

The following questions were by Caltrans to judge the highway users’ reaction to the I-15 rehabilitation project.

1. How often do you drive through the project location?
   1. More than once a week
   2. Weekly
   3. Monthly
   4. Less than once a month
2. Have you driven through the project site during a weekend closure?
   1. Yes
   2. No
3. What is your preferred method for getting road conditions and traffic information?
   1. Newspaper
   2. Radio
   3. Television
   4. E-mail
   5. Internet
4. When using the Internet to plan your drive, what is your primary online source?
   1. Google
   2. Caltrans Web site
   3. Facebook
   4. Twitter
   5. I don’t use the Internet to plan my drive
5. How often do you seek or receive Interstate 15-ONTFIX traffic-related information?
   1. Daily
   2. Weekly
   3. Biweekly
   4. Monthly
   5. Never
6. How helpful are the Interstate 15-ONTFIX project information updates in planning your commute?
   1. Not helpful
   2. Somewhat helpful
   3. Adequate
   4. Very helpful
   5. Not applicable
7. Please rate the importance (1–5) of the following information sources: (1 = Least Important; 5 = Most Important)
   1. Project brochure
   2. Project rack card
   3. E-mail alert
   4. Twitter update
   5. Radio advertisement
   6. Newspaper advertisement
   7. Public meeting
8. Extended (55-hour) weekend closures help Caltrans build a longer lasting pavement. They require significantly fewer closures than if the work is only done at night. Thus, fewer extended weekend closures are preferred over many more nighttime closures.
   1. Strongly disagree
   2. Disagree
   3. Neither agree nor disagree
   4. Agree
   5. Strongly agree
9. This project widened bridges and paved the median to avoid reducing the number of lanes during construction and to allow replacing deteriorated pavement with a longer lasting concrete. Thus, the 20 percent additional cost was worth it.
   1. Strongly disagree
   2. Disagree
   3. Neither agree nor disagree
   4. Agree
   5. Strongly agree
10. Caltrans is testing the use of a precast pavement (Super Slab®) on a small portion of this project. This product has an estimated 30 to 40 year pavement life, and can be placed during nighttime closures. Traditional pavement placed in similar closures has an estimated 10-year life. Although this product costs 1.5 to 2 times more, Caltrans should use this product in pavement work for areas of very high traffic.
    1. Strongly disagree
    2. Disagree
    3. Neither agree nor disagree
    4. Agree
    5. Strongly agree
11. Please indicate your agreement or disagreement with the following statement: I support the measures Caltrans took to minimize impacts to traffic for this project.
    1. Strongly disagree
    2. Disagree
    3. Neither agree nor disagree
    4. Agree
    5. Strongly agree
12. Please indicate your agreement or disagreement with the following statement: I am satisfied with the rehabilitation of the pavement constructed in this project.
    1. Strongly disagree
    2. Disagree
    3. Neither agree nor disagree
    4. Agree
    5. Strongly agree
