Abstract:This research project aims to ease the process of Roadway Sign asset management. The project utilized handheld computer and global positioning system (GPS) technology to capture sign location data along with a timestamp. This data collection effort was designed to replace the handwritten forms used to collect sign information. This technology potentially can reduce the amount of time it takes to collect sign location and inventory data. Desktop software was developed to process the collected data. Reports are available, which look identical to the handwritten reports. The software records coordinates of the sign, and the road location and other components. These data elements allow managers to determine if signs have not been maintained for extended periods of time. This lets them generate a list of signs that should be replaced or reviewed. To complete this project continued development should occur. The second phase should contain tasks to integrate the inventory system with the statewide inventory system and provide additional software functions for the users.
Results from this study show that all districts in the NDDOT can benefit from a program that automates the sign inventory process. Data from the program can be used to generate locations of signs and mark signs that need to be examined. This could lead to efficient methods for sign replacement.
