The Harmonized Traffic Measurements layer displays "harmonized" real-time traffic data.
The real-time traffic data are collected from different data sources and automatically harmonized.
The data is used to get the 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 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).
