About the research

Abstract:

In this project, an alternative work zone warning sign for a lane split with two lanes around one side and one lane around the other side of the work area will be tested. The evaluation will incorporate field data, stakeholder interviews, and driver surveys from a bridge rehabilitation project. The travel time data will also be analyzed to assess the effects of work zone and work zone signage.
