How can traffic predictions help drivers avoid traffic?
More and more drivers are relying on navigation applications and devices to guide them through the fastest routes and avoid hitting congestion. The best navigation devices use advanced traffic prediction services for accurate estimated times of arrivals (ETAs) and optimized routes during a driver’s journey.
So how does TomTom calculate accurate traffic predictions?
TomTom Traffic delivers two kinds of information in real time: traffic flow speeds and traffic congestion/incidents.
Updated every 30 seconds, our service generates a true picture of traffic for unmatched road network coverage. This information helps users plan trips and daily commutes for a faster and more relaxed journey.
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. 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.
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). On top of this, unpredictable events such as bad weather conditions or unplanned large protests pose challenges to traffic prediction.
