• Abstract:
  Maryland State Highway Administration (SHA) has a rich data archive of the messages posted to the ; Dynamic Message Signs (DMS) and the time stamps when they were posted and taken down. The archive ; also contains traffic information surrounding the DMS signs, such as traffic volumes and speeds from ; various point or probe-based sensors. In this project, the research team used this data archive to study the ; impact of DMS messages on traffic conditions. Multiple Bluetooth sensors were deployed on a major ; travel corridor in the Baltimore Metropolitan Area to determine vehicle travel times and to monitor traffic ; diversions.
