SPR-4545: Alternate Interchange Signing Study for Indiana Highways

Current highway interchange signs are designed based on established standards, but some drivers have expressed that signing is confusing, not intuitive or perhaps not explanatory enough. This project is to develop possible recommendations for the better design of interchange signing in Indiana to improve the safety and efficiency of highway traffic operations. Naturalistic driving data collection and driver survey will be the means to collect information.
