• Abstract:
  Traffic congestion is a prevalent issue during peak hours on United States roads. In growing cities such as Charlotte, North Carolina, efficient congestion management is essential to ensure a good level of service for the mobility of people and goods. Maintaining speed variation below a certain level based on road functional class, time of day, and day of the week is crucial for smooth traffic flow—which, in turn, efficiently and safely gets people and goods where they need to be. This study focuses on identifying road links in Charlotte suitable for implementing variable speed limit (VSL) signs. The objectives are to compute and evaluate traffic speed measures by day of the week and time of the day, to explore their association with the speed limit or reference speed by road functional class, and to provide guidance on identifying road links susceptible to variations in traffic speeds for implementing VSL signs.
