Dedicated Short Range Communications - Portable Changeable Message Signs for Work Zone Warnings
Date Posted:	3/12/2013
Description:	The University of Minnesota Center for Transportation Studies has released a report that explains a hybrid traffic-information system for snow plow operations and work zones that combines dedicated short-range communication (DSRC) technology and portable changeable message signs (PCMS) to improve traffic mobility and driver safety. The system uses DSRC-based vehicle-to-infrastructure and vehicle-to-vehicle communication to identify work maintenance vehicles in the area, acquire information such as travel time and the starting location of congestion, and then disseminate this information to both DSRC-equipped vehicles and DSRC-equipped PCMS located overhead or alongside the road. It communicates with drivers of DSRC-equipped vehicles, as well as other drivers via the PCMS, to warn them they are approaching work operations (road construction or plowing) on or near the roadway ahead or areas of congestion.
