A Traffic is a collection of traffic sources which may be queried to determine the speed of traffic along a given link. GeoBase provides support for INRIX and HERE traffic data (incident, predictive and real) as well as a HistoricalTrafficSource class. In addition to these supported data sources it is possible to create your own data source, simply by implementing the ITrafficSource interface.

The TrafficFetcher class is used to retrieve an up-to-date Traffic object based on traffic information from the Traffic's sources by providing the GetLatestTraffic(DateTime) method, which can be called synchronously, or asynchronously.

The TrafficInfo class describes a unit of traffic. A traffic unit knows only its speed. A TrafficRenderer may be used to render a specified Traffic unit on a map. The TrafficRenderer implements the IMapRenderer.

The TrafficRouting class may be used to route through Traffic. The class is used to route through Traffic using Directions.

Classes

	Class	Description
	GeostreamTraffic	A GeoStreamTraffic is a Traffic designed for use over GeoStream.
	HEREIncidentTrafficSource	This class supports HERE traffic incidents (such as an accident or road closure).
	HEREPredictiveRealTimeTrafficSource	This class supports HERE predictive real-time traffic
	HERERealTimeTrafficSource	This class supports HERE real-time traffic data
	HistoricalTrafficSource	This class supports historical traffic data, contained within GBHB files.
	InrixIncidentTrafficSource	This class supports real-time INRIX V1 incident traffic data.
	InrixPredictiveRealTimeTrafficSource	This Inrix V1 traffic source includes both current data and predicted data for the next hour.
	InrixRealTimeTrafficSource	This class supports INRIX V1 real-time traffic data.
	InrixV2TrafficSource	This Class supports Inrix V2 traffic data format
	LinkIdToTMC	This class is used to retrieve TMC (Traffic Message Channel) codes specific to a given link ID.
	NavteqIncidentTrafficSource	Obsolete. This class supports NAVTEQ traffic incidents (such as an accident or road closure).
	NavteqPredictiveRealTimeTrafficSource	Obsolete. This class supports NAVTEQ predictive real-time traffic
	NavteqRealTimeTrafficSource	Obsolete. This class supports NAVTEQ real-time traffic data
	TMCTrafficBase	Implemented by derived classes to support INRIX traffic data and prediction.
	Traffic	A Traffic is a collection of traffic sources which may be queried to determine the speed of traffic along a given link.
	TrafficFetcher	The TrafficFetcher class is used to retrieve an up-to-date Traffic object based on traffic information from the Traffic's sources.
	TrafficInfo	This class describes a unit of traffic.
	TrafficRenderer	A TrafficRenderer may be used to render a specified Traffic unit on a map.
	TrafficRouting	This class may be used to route through Traffic.

Interfaces

	Interface	Description
	IBatchTrafficSource	An IBatchTrafficSource provides bulk querying of traffic data.
	IGenericTrafficSource	Provides a common ancestor for all Traffic Source interfaces. Traffic Source interfaces are implemented to resolve a source of traffic data and a DateTime value to a TrafficInfo.
	ILinkTrafficSource	Implemented to resolve a given LinkId and DateTime to a TrafficInfo.
	ITrafficItem	An ITrafficItem object provides information about a single StreetLink. Implementors of IBatchTrafficSource should call ITrafficItem.SetSpeed to specify traffic speeds.
	ITrafficRequest	An ITrafficRequest provides access to or more ITrafficItem objects each containing traffic information for a single link. ITrafficItem.SetSpeed should be used to set the speed of each ITrafficItem as appropriate.
	ITrafficSource	Implemented to resolve a given TMC code and DateTime to a TrafficInfo.

Enumerations

	Enumeration	Description
	TrafficDirectionType	Describes the direction of travel along a street link.
