Geographic Coverage

Tranzia calculates routing risk using hyperlocal safety data. We transparently list every dataset used in our scoring algorithms.

Policy for Uncovered Areas

For any location outside our designated coverage zones, Tranzia applies a standard baseline risk score. We do not impute safety data where we lack verified sources.
