Local calibration builds defensible AADT estimates by training volume models on an agency's own ground-truth counts instead of generic regional data, strengthening HPMS/MIRE reporting, corridor studies, and safety analyses along the way. From gathering count records to calibration, validation, and delivery through iNode, the full path to locally accurate volumes is laid out step by step.

Bluetooth and radar sensors measure different things and are most effective when used together. Combining roadside sensors with probe-based mobility data gives agencies both location-specific detail and broader network coverage.

Traffic data collection has evolved from manual studies and fixed sensors to large-scale mobility data, with each method offering different strengths and limitations. The most effective approach today is integrating these data sources to achieve more accurate, scalable, and comprehensive insights into transportation networks.

Accuracy in big data isn’t a single number, it’s context-dependent, metric-specific, and only meaningful when validated against the purpose it’s meant to serve.
