Note: I've posted Becky's use cases here.

A prototype of the Traffic Cop is here
A user accesses the techniques repository via the "traffic cop", which is has a condensed list of all the guidelines, and summary sentences of the success criterion. The user scrolls to the guideline and success criteria they want to fulfill and selects the technology (or technologies) that they would like to use to fulfill that criteria. The Traffic Cop then directs the user to appropriate techniques in the repository. Each page on the repository will have XSLT generated text of only those techniques the user selected along with the text of the Guideline and Success Criteria that they want to fulfill. There will also be a link on the repository page that will allow the user to enter the original techniques document at that point. (i.e., HTML Technique 1.1)

Option 1 for "Assistant Traffic Cop": Prototype of Traffic Cop Helper (menu)
Option 2 for "Assistant Traffic Cop":Techniques Repository for those coming from the guidelines (checkbox driven)
A user is reading the WCAG 2.0 Guidelines and wants to find techniques that can fulfill the success criteria they are reading. The guidelines document will have a link after the success criteria that will bring the user to the Assistant Traffic Cop. The Assistant Traffic Cop presents a page that contains the Guideline and Success Criteria that came from in the WCAG 2.0. The "Assistant traffic cop presents a menu (or list of check boxes) of technologies that can help fulfill that success criteria. The user selects the technology (or technologies) that they would like to use to fulfill that criteria. The Traffic Cop then directs the user to appropriate techniques in the repository. Each page on the repository will have XSLT generated text of only those techniques the user selected along with the text of the Guideline and Success Criteria that they want to fulfill. There will also be a link on the repository page that will allow the user to enter the original techniques document at that point. (i.e., HTML Technique 1.1)
