This 90 minute workshop will discuss the effectiveness of various work zone countermeasures used to reduce speeds and address crashes in work zones.  General countermeasures, such as dynamic speed feedback signs and  transverse rumble strips, are presented along with the impacts of other work zone features on speed and driving behavior.  The workshop highlights information gained from a recent project which utilized the SHRP 2 data to evaluate driver behavior in work zones.
