The Estimated Traffic layer displays the "estimated" traffic data.
The estimated data is collected from different data providers.
These data providers can be selected from the LAYER OPTION area.
You can select:
- One provider
- All the providers at once
The collected data is used to get a specific measurement of the ratio V/V0, which gets associated to a specific color.
The different colors represent different partitions of the V/V0 ratio.
V is the measured speed, while V0 is the free flow speed - that is, the speed that you can reach on a specific street or link without traffic constraints (free flow).
