Appendix D: Amplifying Questions

The scan team developed the following amplifying questions to assist the hosting organizations in focusing their presentations on specific areas of interest within the main topic of this international scan. The questions represent the most essential elements or issues within the topic of safety applications of ITS technologies and should not be considered all inclusive. Simply stated, they were drafted both to provide an outline of the scan team's major areas of interest and an opening point in the discussion on this very important and multidimensional subject.

1. Automated Enforcement of Speed Limits and Traffic Signals
   1. What technologies are deployed in vehicles and/or the infrastructure to achieve automated enforcement?

4. Identification and Prioritization of Safety Problem Areas
   1. What ITS technologies are used to assist public agencies in identifying safety problem areas, and how are they utilized to establish priorities for improvements?
   2. How has the use of ITS technologies assisted your agency in more effectively addressing safety-related problems in your transportation system?
   3. What public involvement processes are in place to allow public input into establishing priorities?
   4. How have you measured your success in this process?
5. Selection of ITS over Traditional Countermeasures for Safety Problems

   3. How have performance measures been used to determine the success of the pedestrian and bicycle safety measures that have been deployed?
9. Navigation, Traveler Information, and Signage Issues Related to Safety
   1. What ITS technologies are being utilized to improve the navigation, traveler information, and signage components of your transportation system?
   2. How are these technologies identified, prioritized, and deployed?
   3. How have performance measures been used to determine the success of the navigation, traveler information, and signage elements?
10. Collection of Safety-Related Data Elements
    1. What safety-related data elements are deemed critical to the decisionmaking process when it comes to deploying ITS technologies to enhance safety on your transportation system?
    2. What privacy issues have resulted from efforts to collect safety-related data and how have they been addressed?
    3. What jurisdictional issues have had to be addressed in deploying collection systems for safety-related data elements?
