Lesson Learned

Temporary roadway configuration changes, such as, work zones, temporary traffic control, traffic incidents, and unplanned incidents can be challenging for Connected and Automated Vehicles to navigate. Solutions that allow CAVs to automatically detect changes in a roadway configuration should be supplemented with a standardized data solution to be safer and more effective.
  • If deploying applications that use DSRC to provide work zone and roadside worker support, workers must update the data constantly for the applications to be effective.
  • If deploying DSRC applications that require absolute lane-level positioning accuracy, an RTCM correction can be utilized to improve vehicle localization.
