Which term best describes flow facilities that have controlled and uncontrolled access points?

• A. Intermittent flow facilities
• B. Interrupted flow facilities
• C. Constant flow facilities
• D. Restricted flow facilities

Answer: (B)

Flow facilities are described by whether traffic can move through them without stops or if it is regularly interrupted by control devices or access points. When a facility includes points where entry and exit are managed (controlled) and other points where access is open (uncontrolled), vehicles will be stopped or slowed at these points, causing the flow to be interrupted. That’s why the best term is interrupted flow facilities. Intermittent flow would imply flow happens in bursts for reasons other than deliberate access control, constant flow means no interruptions at all, and restricted flow refers to limited capacity without specifically capturing the presence of control points that interrupt movement.
