GIS-BASED MANAGEMENT SYSTEM FOR PAVEMENT MARKINGS AND MARKERS

The management of pavement markings and markers is critical to public agencies responsible for roadway operations and traffic safety. Geographic information systems (GIS) technology has been adapted by an increasingly large number of agencies to plan and manage their resources in this regard. This paper describes the development and application of an innovative GIS-based management system for pavement markings and markers. The system facilitates developing and maintaining an inventory of pavement markings and markers for individual links on a road network and performing various queries and analyses using this information. It is based on a set of standard cross-sectional lane design configurations for links. Quantities of materials required for each design category and installed unit costs of the materials are maintained in a master spreadsheet that is linked to the GIS program. The user selects a link or a set of links from the road network using the point and click features in a GIS interface. Using information such as link length maintained in the GIS environment, the user input is kept to a minimum. Each link is assigned a unique identification number. It is coded based on the type of materials used and its cross-sectional design. The GIS program is linked to a series of spreadsheets that are used to calculate the quantities of materials used and their costs. The application of the system is demonstrated using a portion of the road network maintained by the Department of Public Works, Clark County, Nevada. The system provides assists managers and policymakers in evaluating safety, fiscal planning, and allocation of resources. It also helps compare the performance of various materials used on the road network.
