A priority rating system for highway maintenance

The purpose of the project was to design a system of computer programs to store and manipulate data concerning the physical characteristics and measurable defects of the roads in Durham County, based on the recommendations of the Marshall Committee on Highway Maintenance. From the extent and severity of defects present, in conjunction with the physical characteristics of the section of road, remedial treatments and priority rating points can be assigned. Thus listings can be produced giving remedial treatments necessary for sections of road making up the highway network, in order of urgency. The system will eliminate from the listings those sections of road requiring no remedial work and indicate where a greater cost effectiveness is given by replacing remedial work by a minor improvement scheme (e.g. realignment of the road).
