All This Data, Now What?
- Are we installing devices where they can be of the most impact?
- Are we staging HEROs and CHAMPs appropriately for incident response?
- How do we find out about incidents more quickly and ultimately clear the
roadway more quickly?
- What is the true impact of a crash on delay?
