Journal of Traffic and Transportation Engineering (English ed. Online), 2021 This paper evaluated the significance of the posted differential speed limits (DSL) on traffic safety and operation along interstate highways in South Carolina. This paper defines DSL as the difference between the posted maximum and minimum speed limits.
