What is the difference between TomTom Traffic Index and Area Analytics?

Our Traffic Index, free and updated annually, is ideal for broad, comparative insights across 500+ global cities. It delivers key metrics like congestion levels, travel speeds, and travel times per 10 km, alongside seven-day trends, and annual benchmarks for a quick, standardized view.

Area Analytics is an advanced traffic analytics tool for cities, governments, and organizations that need precise, tailored data. Area Analytics enables you to define any custom area, analyze traffic for specific dates, months, years, or even hourly timeframes. You can also refine your analysis by specific days or road classes and conduct direct comparisons between user-defined zones. It puts the power of detailed traffic analysis directly in your hands.

How does TomTom calculate congestion levels?

Congestion levels are calculated by comparing travel times with the baseline travel time (when traffic is in a fluid, free-flowing state). Congestion levels are expressed as a percentage, which is representative of the increase in travel time due to congestion. For example, a congestion level of 40 means that, on average, journey times are 40% longer than when traffic is free-flowing.

How many countries does Area Analytics cover?

We provide coverage in 77 countries worldwide, and the number is growing.
