The District Department of Transportation (DDOT), like many transportation agencies in the United States, needs a comprehensive system for inventory purposes and maintaining records of traffic signs, especially for trucks and buses. To address this need, state highway departments around the country have, or are beginning to develop truck or bus restriction/limitation sign inventory systems that allow their personnel to count, locate, and monitor the maintenance and condition of their sign inventories. The database can also be used by construction, maintenance, and engineering personnel to monitor sign condition, track performance changes over time, determine locations where additional signs may be needed, monitor field maintenance and replacement programs, and locate unwarranted or “exception” signs while helping in making necessary planning decisions. The database may also be integrated into existing geographic information systems (GIS) to form more robust asset management systems that can include statistics on a variety of highway features such as signs, guardrails, traffic signals, pavements, bridges, survey markers, etc. This project is primarily focused on developing a comprehensive database or list of truck and bus restrictions or limitations signage in the District of Columbia.
