How do you gather the traffic data?
How do you gather the traffic data? We use many methods for gathering traffic information in the area including (but not limited to) DoT and Proprietary Traffic Cameras, DoT Speed Sensors, INRIX GPS Sensors, Airborne/Mobile Spotter Vehicles, Digital Scanners that cover many local emergency services, Police Callouts, and Traffic “Tip Lines”. The local operations center staff use their resources to locate and verify the traffic data before entering it into our system.

What roads are covered?
The RDS-TMC service is designed to be primarily a freeway service, used on limited access highways in your local region. Secondary roads may have coverage for some incidents, but not with flow or congestion information.

How does FM Traffic work?
The data channel runs concurrently with the audio channel, and you don’t need to have your radio tuned to any particular station for your TMC receiver to pick up signal. Your GPS tunes using its own FM receiver, completely in the background, and will automatically select the best station in your area. You can find a list of stations in Navigation Coverage Areas.

Do I need to tune my radio to a specific station?
No. This is completely independent of your car or portable radio. The FM receiver is inside of the antenna on most personal navigation devices and wired into most automobiles with real-time traffic.

Will I hear live traffic reports on my radio?
No, this is completely independent of your car or portable radio. Our product is raw traffic data that is sent to your device. Different devices have different applications that use this data, and some may have audible alerts. Check your device’s manual to see what it offers.

How can I increase the signal strength to my receiver/antenna?
First, make sure you have connected your device to the internet and checked for the latest updates for your device. Second, make sure you have followed your manual’s instruction regarding setup. Most devices must be connected to both the outlet and the device in order to get a signal since the antenna/receiver is built into the power cord. Also, some devices must be fully docked in order to work. Finally, try to expose the antenna to as much “sky” as possible and do not use a “splitter” device to share the power outlet with another device (like an iPod) as this may cause interference with the receiver.

Where can I ask specific questions about my traffic data?
The best way to get information for a specific event is to note the date, time, highway name and direction and nearest cross street. We have extensive data archives and can answer your queries much easier with specific data. For those questions and any not answered in this FAQ send your request/question to info@totaltraffic.com.
