SiriusXM Traffic collects data from departments of transportation, police and emergency services, traffic sensors and cameras, airborne reports and other sources. Accurate incident information is dependent on locating, verifying and reporting the incident as soon as it occurs, and then transmitting it to your navigation system’s display.
Proper maintenance of traffic sensors is essential in creating accurate traffic information. Many of the sensors have inherent reporting delays up to 20 minutes. We transmit updated incident and traffic flow info as soon as we receive it. Then it typically takes less than two minutes for traffic data to appear on your navigation system screen.
