Google Maps Rival Explains Why Navigation Apps Can’t Provide Fully Accurate ETA
The key word here, however, is “estimate”, Because the ETA you see on the screen is not always 100% accurate. And all of this for a number of very good reasons.
TomTom, one of the leading navigation software companies and the developer of several alternatives to Google Maps, recently discussed the challenges of getting a fully accurate ETA, explaining that more often than not being 100 percent is extremely difficult. .
One of the reasons is the traffic itself, which is difficult to predict despite the AI-based systems that have been launched recently. Accidents, traffic jams, and construction zones could all slow down drivers, thus affecting ETA and ultimately making the navigation app look silly.
Then it is the perception of ETA, as TomTom explains that a navigation app cannot provide an estimate based on how each person drives. Some are quick and aggressive, others just go for a more conservative driving style, so ultimately ETA could be different again for the same route and destination, it all depends on how we drive.
These challenges can still be met, says TomTom, although it all comes down to a mix of next-gen systems that include detailed road information (such as curvature, grade, speed limits, traffic lights, rules and lane information), historical, live and predictive traffic systems to anticipate what is happening on the road, as well as more advanced routing algorithms.
But at the end of the day, every little thing that happens on the road can affect ETA. And that’s why it’s always important to keep in mind what ETA stands for. This is the estimated time of arrival, and an estimate is pretty much a rough calculation that is more of a guess than a precise number.
