![]() TomTom's historical traffic database has 2,800,000,000,000 (2.8 trillion!) kilometers of trip data, shared by our community of drivers since 2008. To ensure drivers have the most up-to-date and accurate traffic information, we process billions of anonymized data points every 30 seconds. ![]() What is the traffic data collection process?įor the best traffic predictions, data is key. On top of this, unpredictable events such as bad weather conditions or unplanned large protests pose challenges to traffic prediction.Ī representation of real-time traffic in the TomTom Go Mobile navigation app. However, much like weather forecasts, the longer the time horizon, the bigger the challenge to achieve highly accurate predictions ahead of time (except during nighttime periods where free-flow speeds are most common). If a driver has an important meeting planned for the next morning, TomTom Traffic gives the user the option to plan ahead to avoid peak hours and arrive on time. TomTom calculates traffic flow speeds and congestion in real-time, and users can also use this information to predict what the traffic will be up to 24 hours ahead of time. This information helps users plan trips and daily commutes for a faster and more relaxed journey. Updated every 30 seconds, our service generates a true picture of traffic for unmatched road network coverage. TomTom Traffic delivers two kinds of information in real time: traffic flow speeds and traffic congestion/incidents. So how does TomTom calculate accurate traffic predictions? The best navigation devices use advanced traffic prediction services for accurate estimated times of arrivals (ETAs) and optimized routes during a driver’s journey. ![]() More and more drivers are relying on navigation applications and devices to guide them through the fastest routes and avoid hitting congestion. How can traffic predictions help drivers avoid traffic? Highly accurate traffic information also helps governments by supporting the development of smart and sustainable mobility systems to reduce overall congestion levels.Ī visual pattern of congestion comparing a normal weekend day to a public holiday. You can’t always avoid traffic but with accurate traffic predictions you can make smarter choices that can save you money, time and increase overall road safety. However, the largest increase in global traffic congestion is due to one main cause: there are too many vehicles for a road network with a limited capacity. Bad weather conditions also result in lower-traffic flow speeds, while poor traffic signal timing limits capacity on smaller inner roads. Road incidents such as accidents and roadworks often cause unexpected delays. ![]() The most common causes of traffic congestion are known by any driver who has come across a traffic jam on their journey. Congestion is a global problem that impacts all levels of society. At the same time, large amounts of congestion impact governments who need to keep traffic flowing for the movement of goods, reducing pollution in certain areas, and for the safety of those on the road. Traffic congestion costs people valuable time, fuel, and frustration every single day. Have you ever sat in traffic wondering how much time you could have saved if you weren’t stuck in gridlock? What about if you had taken the left turn at the junction instead of continuing on the highway only for a never-ending queue of vehicles to greet you? Traffic prediction is the task of forecasting real-time traffic information based on floating car data and historical traffic data, such as traffic flow, average traffic speed and traffic incidents.
