3. INTERNET DATA ACCESS TOOL The HTDC Internet Data Access Tool provides access to a web-based catalog of archived data files of heavy-truck operations in real-world driving environments. This tool allows the user to retrieve data collected during the FOT. The application has the capabilities to locate and summarize data files for downloading purposes based on user-selected parameters. 3.1 PURPOSE This application (Fig. 28) was developed to provide data mining capabilities of the extensive data set collected during the FOT. This tool enables the user to search the database for parameters to extract data meeting certain criteria (e.g., road conditions, tire type, road grade, weather conditions, etc.), and download the zip files for analysis.
