Data
Capture Challenge: Bandwidth Overload
§Issue:
Potential data explosion due to new forms of data will likely over-burden the computational and communication
systems
□Large
volumes of data with connected vehicles, infrastructure, and travelers
▪Approximately 1.2 MB of accelerometer data generated per vehicle per
mile (Source: Cooperative Transportation Systems Pooled Fund Study on Pavement
Assessment by Auburn
University)
▪Translates to 2 TB of data per day just for pavement assessment for
Washington, DC
□Capturing,
transmitting, cleaning, and storing large volumes of data can over-burden the system and be cost-prohibitive
§Innovation:
Dynamic Interrogative Data Capture (DIDC)
