HERE Real-Time Traffic leverages two types of data: flow data and incident data. Flow data analyzes the speed and congestion levels, while incident data covers road closures, collisions, roadworks and more.

HERE Real-Time Traffic is a comprehensive, global traffic service that uses up-to-the-minute information about traffic flow, incidents and road works to support drivers in reaching their destinations efficiently and stress-free.

How HERE Real-time Traffic measures congestion

Our congestion score provides a value for the amount of traffic in a specific radius around each venue for highways and arterial roads. The value, between 0.0 and 10.0, indicates the expected quality of travel:

• 0 to <4 = free traffic flow 

• 4 to <6.3 = minor congestion through heavier traffic, but not yet considered slow 

• 6.3 to <8 = heavy and slow traffic 

• 8 to <9 = heavy and queuing traffic 

• 9 to <10 = stationary traffic 

• 10 = reserved to represent a blocked roadway
