The Port Orange Pavement Management System (POPMS) was developed cooperatively by the city of Port Orange, Florida, and the Center for Urban Transportation Research (CUTR). This subject is timely for local municipalities contemplating the development of a pavement management system (PMS). Recent FHWA policies now require that each state have an operable PMS by January 1993 in order to receive federal aid funding. It is anticipated that the states will establish similar requirements for local municipalities to continue receiving state matching funds. In particular, the system "customizing" process serves as a valuable guideline and case study for local governments seeking to investigate and implement a small-scale PMS. This project was set in motion to provide a rational basis for determining the financial deficiencies of roadway maintenance and rehabilitation to be met by a proposed transportation utility fee (TUF) as a means of generating much-needed revenue. The city of Port Orange, with a population of 35,000, initiated an investigation to develop a simple but comprehensive PMS for its 142-mile (228.62 km) street newtork. Very minimal street inventory data, limited field staff time availability, and only elementary knowledge of PMSs were all considerations. Before a pavement condition survey was carried out by the city, CUTR conducted a training session on city street network sampling strategy, visual condition survey techniques, development and completion of conditions survey forms, and pavement surface-distress-type classification guidelines. CUTR prepared a customized Pavement Conditions Survey Manual to facilitate city staff training. Upon the city's completion of the field condition survey, the pavement condition data were cataloged into a microcomputer assessment model. A total of 386 sample segments, or about 6% of the total city street surface area, were identified and evaluated. (The POPMS model is a modified version of a program being utilized by Carson City, Nevada. The modifications reflect specific maintenance and rehabilitation decisions by Port Orange.) A POPMS Evaluation Report and "report card" were prepared by CUTR to translate the results of the assessment model to city policy makers, to quantify and set priorities for specific pavement maintenance and rehabilitation project costs, and ultimately to predict and combat the effect of delayed expenditures more effectively. |
