SPR-4628: Exploration of Color Patterns for Improving Work Zone Safety and Perception

Indiana Department of Transportation (INDOT) had 5,470 collisions every year on average between 2015 and 2019, with many occurring in Indiana work zones and causing significant loss to both construction workers and vehicle drivers.
