Introduction to HERE Traffic API v7

The HERE Traffic API is a REST API that provides real-time traffic flow and incident information. This document introduces the HERE Traffic API and explains key concepts, while providing examples and information on resources, query parameters, response structures, and data types.

The HERE Traffic API supports the following use cases:

• Provides access to real-time traffic flow data in JSON, including information on speed and jam factor for the region(s) defined in each request. The HERE Traffic API can also deliver additional data such as the geometry of the road segments in relation to the flow.
• Provides aggregated information about traffic incidents in JSON, including the type and location of each traffic incident, status, start and end time, and other relevant data. This data is useful to dynamically optimize route calculations.
