For how long does the computer save AVL data, specifically vehicle tracking coordinates?

The correct answer reflects the policy regarding the retention period for AVL (Automatic Vehicle Location) data, specifically vehicle tracking coordinates, which is set at 180 days. This timeframe allows for adequate data availability for operational needs, such as analysis of vehicle use, response times, and tracking of activity patterns over a significant period.

Maintaining AVL data for 180 days also strikes a balance between operational requirements and data management considerations, such as storage limitations and privacy concerns. This retention period ensures that law enforcement agencies have sufficient historical data to review incidents or patterns of interest, while also allowing for the regular purging of outdated data to maintain system efficiency.

Other options present varying lengths of time that do not align with the established guidelines for AVL data retention. Shorter time frames, like 30 and 90 days, would limit the ability to conduct extensive reviews or analyses, while a longer duration, such as 365 days, may not be practical due to storage capacity and policy constraints regarding data retention.
