Traffic information doesn't interfere with FM or satellite radio reception, so you can continue to listen to either source while you receive traffic signals. The traffic information comes from a variety of sources, including commercial traffic data providers, departments of transportation, police and emergency services, road sensors, traffic cameras, and even aircraft reports. These providers work with the two main companies behind map data for the U.
In terrestrial FM applications, the traffic signals are broadcast over the FM Radio Data System RDS , a special application of the radio band for sending small amounts of digital information.
Most car stereos support FM RDS signals, which is how you can see radio station call letters or artist and song title information on your display when tuned to certain stations. HD Radio signals broadcast traffic data in a similar fashion, but since HD Radio signals are able to carry more information, they can provide real-time updates more rapidly — up to four times more quickly than FM RDS in some cases. To use the service, simply program a destination into your navigation system.
As you drive, your system will receive and deliver alerts whenever a traffic incident comes up. You'll get both an audible warning and a visual indicator on the navigator's map, which shows you where along your route the incident has occurred.
Many systems will automatically suggest alternate routes that enable you to steer you clear of the incident ahead. Traffic incidents include accidents, emergencies, construction, scheduled road closures, and traffic diversions for occasions such as sporting events. Some services even offer detailed information about traffic flow and the average speed along your programmed route in certain high-traffic areas of select cities.
Your primary benefit is time. More often than not, you'll get warnings of traffic incidents along your route with time enough to avoid them. And since you're using the traffic data in conjunction with a navigation system, you'll get suggestions for the most efficient alternate routes. And that means less time spent sitting in gridlock. Traffic-information services also let you get the most out of your navigation system. Normally, you wouldn't use a GPS unit to guide you to work, or to get you back home along familiar roads.
But with real-time traffic info, you'll find that your navigation system becomes an invaluable traveling tool you'll use daily. Basically, all you need to enjoy real-time traffic information is a traffic-ready navigation unit and, usually, an antenna satellite radio antennas can pick up traffic-information signals as well, if you're using a compatible satellite radio receiver. For most portable GPS navigators, the antenna is contained within a special power cable that comes with the device or can be bought separately.
But not all navigators will show traffic reports even when connected to that type of cable — they also need to have compatible built-in software and a receiver to translate those signals. As mentioned above, some newer portable GPS units and in-dash navigation receivers include either a limited or lifetime subscription to a traffic data service, typically for free and in some cases supported by on-screen advertising.
Other devices or sources require a subscription to their service. Currently, the most popular traffic-information services are provided by:. Pricing depends on the source. Coverage currently includes many metropolitan areas. However, the number of cities covered has expanded quite a bit over the last few years.
Rather than try to keep up with the list of cities, here are links to the coverage areas for the three providers listed above. SiriusXM satellite radio NavTraffic. As the in-dash receiver is seen more and more as an extension of the driver's phone or tablet, there has been a noticeable move toward incorporating specialized traffic apps, whether within the navigator or through a connected device. Both apps rely on a combination of map-based traffic data and crowd-sourced reports from vehicles within nearby cellular networks to generate their traffic reports.
If those signals are not present, the apps may be rendered next to useless. App compatibility varies depending on the stereo manufacturer, the phone, and operating system. After calls to Sirius tech support and getting nowhere, I asked about it when I took my car into the dealership for service. They told me that there's nothing wrong with my navigation system, it's SiriusXM not providing the data.
It took half an hour on the phone today with two Sirius representatives before I was transferred to a supervisor. She finally admitted that was the case and refunded my subscription fees.
It's a shame, because the Pioneer U Navi system is very powerful and flexible, far more so than Google Maps. It just doesn't have traffic information very much of the time.
Michael, Fiat is correct. If you add an aftermarket SiriusXM tuner, you'll need to use an aftermarket radio in place of the factory radio. If you decide that's what you'd like to do, give us a call. We can help you with that. Can anyone help me. Just bought a brand new Fiat with a Tom Tom nav system. Fiat says I am stuck as it is factory installed. Is there any way at all to add traffic. Via an antenna or whatever. Any help will be appreciated. Joel, if you need help with your factory navigation, that would be a question for your Toyota dealer.
All the information is merged and evaluated to generate precise real-time traffic information to help you make better decisions on the road. You will know where the congestion is and how long it will take you to get through it. Knowing of the delay is good, but this feature is far more useful than that. You will also receive automatic faster route suggestions so you can take an alternate route to avoid the traffic jam.
This not only saves your time but also optimizes the traffic flow as you do not contribute to making the congestion even worse. Have a look at the infographic below to get a better idea of how this sophisticated system works:. A pretty convenient feature, right? Head over to our e-shop to find out about the pricing options. For example, if lots of data comes in showing cars moving at 20mph on a section of the M1, there is obviously a holdup.
Similarly, if cars are queueing for twice as long as usual at a major road junction, it is obviously more congested than usual. On the other hand, if a city centre road is running at the speed limit during rush hour, this might be a good alternative route for commuters stuck in nearby queues.
The final task is to try and create faster routes for individual drivers who are already on their journey. For some people, this will be impossible, but for many users, it will be possible to take an alternative route that may be longer but quicker. They can then choose to accept the alternative or carry on as they are. You might say that routing lots of extra vehicles away from a queue and onto a quiet road will just result in two roads getting busy.
Secondly, it makes good sense to try and even out traffic distribution across as many roads as possible. The next question is — what type of real-time data is transmitted between a satellite and a receiver built-in a GPS tracker? After that, this type of information longitude as well as latitude is transformed into the address. Bear in mind that the Global Positioning System comes with the databases that contain different types of important information including length of roads, length of roads as well as the average speed of vehicles on roads and other types of data.
This is something that helps a GPS receiver calculate the best possible route for your car and show it to you on Google Maps.
If this is the case, a receiver built-in your GPS system will also need such an important parameter as the height above the earth. What does it mean for a driver? As you can see, drivers can benefit from using a GPS tracking device in a number of ways.
However, using a GPS tracking device also has many other significant benefits for drivers. Most importantly, the innovative GPS tracking devices provide car drivers with the information on the current rout traffic and traffic jams. Use the power of a GPS tracking system to figure out when there is traffic on roads and avoid jams successfully. So can a GPS Tracker be wrong?
