The importance of roadway pavement markings to motorists and pedestrians needs no reinforcement among the staff at the Iowa Department of Transportation (Iowa DOT). With an annual pavement marking program of approximately $2 million dollars and another $750,000 invested in maintenance of durable markings each year, the Iowa DOT is seeking every opportunity to provide all year markings in acceptable condition under all weather conditions. The goal of this study was to analyze existing pavement marking practices and to develop a prototype Pavement Marking Management System (PMMS). A practical and integrated PMMS would allow for more accurate development of annual marking needs, as well as provide guidance on durable pavement marking applications and overall marking strategies on a statewide basis.
