Traffic data

The term traffic data, or road traffic data, means information about passages on a road section. The data usually contains information about the number of vehicles, speeds and vehicle types during a certain period and is collected using sensors in or by the road. Collection and analysis of traffic data is a must for virtually all municipalities, cities and national traffic authorities in the world.


Traffic reports

The traffic report is a key tool in the work with traffic data. Based on collected data, a report is created that describes either the general traffic situation or focusing on a certain aspect of the traffic, e.g. speeds. The traffic report is used for decision-making, during planning of changes and for follow-up of changes already implemented.


Real-time data and ITS

ITS, or intelligent transport systems, is an area with a focus on smarter and more efficient use of the transport network. By controlling traffic and providing better information to road users, trips can be made both shorter and safer. A basic building block in ITS is the availability of real-time data to create information for road users and make decisions.
