GIS Based Integrated System for Analysis, Planning, and Visualization of Transportation Infrastructure, Safety, and Equity in Urban Area

The goal of transportation asset management is to maximize the performance of available assets. Adequate visualization of assets, traffic demand, safety, and other conditions gives a better understanding of the complexity of the existing situation; however, most agencies lack a single tool to visualize such transportation-related information and prepare improvement plans. A prototype data visualization and analysis tool has been created for the city of Columbus, Ohio. It leverages GIS and other reporting tools to capture and show information that is relevant and matters to the people being served. This study demonstrates data visualization examples that utilize data from multiple sources throughout the city to support asset management, enhance the quality of life, and improve traffic safety (as part of the city’s Vision Zero initiative), among other things. It demonstrates the use of tools to visually present transportation assets, their valuation, safety, equity; prepare work plans; and envision the effect of the recommended work plan on predicted transportation network conditions.
