The Florida Standard Urban Transportation Model Structure (FSUTMS) specifies that models use an attribute referred to as UROAD, which is the ratio of the practical to absolute capacity of a model link. This memo demonstrates the role that UROAD plays in the Florida modeling context by examining the impact of different UROAD parameters on total assigned trips, congested trip times, and congested speeds. The UROAD factors currently used in Florida models are listed, along with other associated variable factors, like the alpha and beta parameters and the peak-to-daily capacity ratio attribute.
