Throughout the years, Dr. Moses has been in the forefront of conducting research with practical implications to the driving public. In 2004, through a grant from the Florida Department of Transportation, Traffic Operations Office, Dr. Moses led a research team that evaluated the relevance of the 40 MPH minimum speed limit that was back then applicable on Florida rural freeways. The field data showed that a higher minimum speed limit may decrease speed variability that was evident in the field data. The Florida Department of Transportation implemented a higher minimum speed limit, i.e., 50 MPH as shown in this field photograph.

Dr. Moses was also the principal investigator of a research aimed at developing uniform statewide policy for truck restriction signing. The existing truck lane restriction sign (shown on the left) was thought to be overly long in text and reading time, particularly on high-speed highways. A simple design which tells truck drivers which lane they are restricted from using rather than which lanes they are allowed to use was proposed for statewide use in Florida. The change has since been implemented on the I-75 corridor in Central Florida.
